How to transfer a gas boiler to propane

Transfer of a boiler to liquefied gas alteration and reconfiguration of a boiler for cylinder fuel

The main difference between natural and liquefied gas is that the first is supplied and burned at higher pressure. Automation of ordinary equipment, configured for indicators equal to 6-12 atm. With a decrease in the indicators, a pressure sensor is triggered, turning off the burner.

The work of the heating boiler on the propane-butane mixture requires a change in the configuration and parameters:

  • It is necessary to change the speed of gas.Air mixture.
  • It will be necessary to install a set of jackets for liquefied gas.
  • Configure automation for other work parameters.

Modern single.Circuit and double.Circuit heating boilers are designed to work on liquefied and main gas. Re.Equipment requires the replacement of nozzles and switching the boiler to another mode.

Technical conditions, for the use of liquefied gas in individual boilers not intended for this type of fuel, are significantly different. In addition to replacing nozzles, complex reconfiguration of automation and regulatory reinforcement will be required.

Correctly adjust the supply of gas to the boiler when switching to liquefied gas, set the minimum pressure limit and perform other work yourself, without special skills, is difficult. According to applicable standards, all work must do exclusively licensed specialists.

The technical documentation of heating equipment indicates the minimum pressure in which the burner continues to work. The lower this indicator, the more propane-butane mixture it will be possible to use from refuel fuel capacity. Usually, the container remains from 15-30% of the total volume.

In the section, how to transfer the heating boiler to the consumption of a gas boiler on liquefied gas, it was mentioned about the need to replace nozzles or nozzles. Re.Equipment is required for several reasons:

  • The difference between nozzles for liquefied and main gas lies in different diameters of the exhaust hole. As a rule, nozzles for propane-butane mixture already.
  • After installing a set of nozzles for transferring a heating boiler from natural gas to liquefied gas, the pressure in the system increases slightly.
  • Reduced diameter of the nozzle, leads to a decrease in the supply speed of the gas-air propane-butane mixture. For normal operation, 10 kW of the unit requires that the pressure is not more than 0.86 kg/h.

Nozzles or nozzles are sold with sets. Some manufacturers, in the basic configuration, attach all the necessary reinforcement necessary for converting. In other cases, the kit will have to be purchased separately.

The volume of consumption of liquefied gas in gas heating boilers is indicated in the technical documentation provided by the manufacturer. All models have different and depends on several factors:

The technical characteristics of liquefied gas consumption are also affected by how much the selected model is adapted for this type of fuel. On average, for 10-15 kW of the unit, it will take 2 per week and a month, 9 cylinders.

Theoretically, it is not difficult to reconfigure the heat generator, the main thing is to replace the nozzles responsible for gas consumption in the boiler. After that, it is necessary to configure the gas valve in accordance with the instruction manual. Plus the controller configuration when the unit is automated. A good specialist with tools and equipment for everything about all for half an hour. Maximum.

Instructions for the product may include a section for service masters, where everything is described in detail. But you need to have a pressure gauge for setting gas pressure. The first thing to do is change the nozzles on the ramp of the burner. To do this, remove the front panel or open it. Next, the smell group is unscrewed and removed, and then. The ramp. Jicks are screwed from its inside, which should be replaced.

Currently, total gasification is taking place in our country. In this connection, gas heating equipment is in great demand. Now gas boilers are widespread. Of these, 99% use natural gas as fuel.

What to do if there is no way to use natural gas as a fuel for any reason?

In this case, most gas boilers lend to reconfigure for work on liquefied hydrocarbon gas (LPG). A proponent mixture is used as a LSG.

Props-button mixture-a mixture of liquefied under pressure from hydrocarbon gases. It is delivered to consumers in cylinders under a pressure of 15 bar in a liquid phase or in tanks. When the pressure decreases, it goes into a gaseous state.

For burning a proponent mixture, more air is needed than when burning natural gas.

How to prepare a boiler for work on liquefied gas?

You need to decide on the amount of liquefied gas that you need. With small volumes, liquefied gas can be stored in cylinders. With more significant volumes, it will be necessary to mount the gas tank.

Gazgolder is a special storage tank for liquefied gas.

In the gas boiler, the gas is supplied to the burner through special nozzles, due to which it is sprayed and mixed with air.

To transfer the boiler to liquefied gas, it is necessary to replace standard nozzles with nozzles with a smaller diameter of the conditional passage.

Also, it is necessary to install a gas reducer at the gas inlet in the boiler and configure it to the gas pressure indicated in the boiler passport. After all these events, the boiler will be able to work on liquefied gas.

But it should be remembered that when working on liquefied gas, the boiler loses from 10 to 20 % of its power.

If you need a gas boiler that can work on liquefied gas, then our experts can help you in the selection of such a boiler.

The package will include jetting for working on liquefied gas. In the future, if you decide to switch to natural gas, then you just need to put standard nozzles in place.

Autonomous gas supply to the LPG

Having stopped your choice on LSG, the next step is the question of the actual location of gas tanks and the gas supply of heat.Generating plants.

Two types of containers are used: gas cylinders and gas tank.

Gas cylinder-a steel welded cylinder for liquefied hydrocarbon gases (propane) GOST 15860-84 is designed for transportation and storage of propane with various capacities of 50, 25, 12 and 5 liters (working pressure-1.6 MPa).

The installation of gas supply using small containers should be performed by the number of cylinders of at least 3 pieces. This allows you to increase the surface of evaporation and reduce the risk of freezing freezing

It is important to use pressure regulators with the parameters required for a given boiler and the type of gas. It is not allowed to use regulators not intended for LPG!

Gazgolder-a reservoir intended for storage, regaling of liquefied hydrocarbon gas during gasification of residential buildings, communal and household objects. Gas boards are distinguished by volume (from 0.25 to 100 m2). Unlike cylinders, they provide a large surface of evaporation and a larger storage of LPGs and, as a result, fewer refueling.

In any case, to obtain safe use of LSG, the design of gas supply to the house will be required. The complex and laborious process consists not only in the development of the optimal gas supply scheme of the house, but also includes obtaining a number of permits and registration of the autonomous gas supply system. In some cases, LSG is used as backup fuel, but a number of operations must be carried out to translate the boiler.

When choosing a heat generator, you should pay attention to the possibility of working on a LPG. Not all boilers manufacturers allow a transfer to another type of fuel

Baxi equipment operating on natural gas can also be used as a heat generator on a LPG. To transfer atmospheric boilers and BAXI water heater to a LPG (in the instructions G31), the master-owner is enough to perform three important operations: 1. “Inform” the board that the boiler is now working on the G31 (SUG) (change a number of parameters F, or translate the position of the jumper/tooth.To.Beler GPL); 2. Replace existing nozzles with nozzles with a smaller passage (are acquired separately. Table. 2); 3. Reconfigure the gas valve (according to the G31 parameters).

For condensation boilers, the operation occurs without additional costs: 1. Replace the gas diaphragm located at the output of the gas valve (included in the kit); 2. Install parameters n using the control panel display; 3. Configure the gas valve if necessary.

The use of LPGs with condensation boilers reduces not only the level of emissions into the environment, but also significantly reduces gas consumption.

How to carry out re.Equipment

In order to convert ordinary gas heating equipment into a boiler on propane, it will be necessary to perform the following actions:

  • Replace the nozzles or the entire burner. In modern condensation models, sometimes there is enough ordinary replacement of the cartridge. All these actions should be carried out by professionals with appropriate tolerance. The only way to ensure safe operation of the system after connecting.
  • Perform the installation of the gearbox. A converter that reduces pressure. This step is necessary in order to adapt the boiler to work on the LPG. If there are several cylinders, each of them can be connected to a separate gearbox or general converter.
  • If necessary. Replace the gas valve.
  • If you are supposed to be connected from cylinders, you should take care of installing a mating ramp that allows you to connect them into a single system (up to 10 containers at the same time). Thus, it is possible to maintain a stable level of pressure in the system, reduce fuel consumption and refueling frequency.
  • In boilers with electronic controls equipped with a switch of the type of fuel, it is also required to set the parameter G31 corresponding propane (the default is installed by G20).

In any case, regardless of whether you connect HBO or plan to supply fuel from a gas tank, only professionals can carry out installation or re.Equipment of existing equipment. Otherwise it will be impossible to guarantee the safety of its operation.

Nuances of operation of gas boilers with liquefied gas

Jicks are screwed from its inside, which should be replaced.

Note. The operation of disassembling the burner and replacing nozzles in various models of the units is carried out differently and may be much more complicated. In addition, when switching to another type, fuel boilers require intervention not only in the gas, but also in the electronic part.

Further configuration is carried out using a pressure gauge. You should know that the use of liquefied gas in gas boilers requires adjusting the pressure in the highway leading from an automatic valve to the burner.

Having carefully studied the instructions, you need to find the appropriate fitting and put a hose on it from the manometer, and then, having launched a heat generator, adjust the minimum and maximum gas pressure by a special valve.

Difference of boilers for natural and liquefied gas

  • Less pressure-the supply of the gas-air mixture, is carried out when pressure, not higher than 3-4 MBAR. The supply of main gas is carried out with a pressure of about 0.8-1 bar or 6-12 atm.
  • The need to convert liquid fuel into gaseous-usually a propane-butane mixture is in a liquid state. To turn liquefied “blue fuel” into gaseous, it is necessary to create the necessary conditions.To ensure the stable operation of the boiler, it is necessary to provide constant pressure in the pipeline. All these functions are performed by a gearbox installed between the boiler and the fuel capacity.
  • Efficiency-gas boilers of heating on liquefied gas-butan gas, have a useful coefficient, not lower than 92-95%. For equipment of this type, this indicator is critical due to the high cost of liquefied gas.
  • Nozzles. In their technical characteristics, nozzles differ from those used in boilers working on main fuel.

A gas boiler for burning liquefied propane-butane gas, in most cases, is universal and after reconfigure, can be connected to a main pipeline.

Features and nuances of the installation, connection rules

When performing installation, it is important to strictly observe and take into account a number of requirements. In principle, at 80%, all work is performed as in the case of installing a conventional gas device, but there are some differences:. Installation of the device, which operates from LSG, should be carried out in a room with an area of ​​at least 8 m2; The height of the ceilings in the boiler room is at least 2.3 m; The distance from any side (not the front) of the boiler to the wall from 0.7 meters;

The room should have high.Quality natural ventilation, at least one opening window, a wide passage.

  • Installation of the device, which operates from LSG, should be carried out in a room with an area of ​​at least 8 m2;
  • The height of the ceilings in the boiler room is at least 2.3 m;
  • The distance from any side (not the front) of the boiler to the wall from 0.7 meters;
  • The room should have high.Quality natural ventilation, at least one opening window, a wide passage.

Provided that all the requirements regarding the choice, installation and connection of the heating device are clearly observed, the further operation of the device on liquefied gas will be pleased with stability and safety, efficiency and efficiency in operation.

How to redo the boiler for propane from cylinders

In order for the gas boiler to work on propane, it is necessary to perform some actions to re.Equip the device. However, not every device can be converted, in the technical documentation it should be written that it can work with gas pressure at 3-4 MBAR.

So, if everything is normal with the documentation, we will consider how to remake it to work with propane (G 31):

  • You need to replace nozzles or burners. However, some devices are already manufactured by the manufacturer to work on different types of gas, and for the transition you just need to replace the cartridge. Bound gas nozzles
  • Install a gearbox. During refueling the cylinder, the gas is supplied under pressure, this converts it from a gaseous state into a liquid. In order to return the gaseous state, a gearbox is used, gas consumption should be about 1.9-2 m3 per hour.
  • It may be necessary to replace the gas valve.
  • It is not allowed to store or install cylinders in the same room with a boiler. They must be installed on the street or in the neighboring room in an equipped cabinet, at a distance of at least two meters from the boiler.
  • It is forbidden to store empty containers in the building.
  • When freezing of cylinders is not allowed to heat them with fire. It is necessary to perform insulation measures of the cabinet with non.Combustible heat.Insulating materials.
  • Once every four years, you need to take the cylinders for verification.

Types of boilers on propane

Three types of units are presented in the household equipment market. These are single.Circuit, double.Circuit and condensation boilers. They perform similar tasks, but differ in terms of the principle of device and functionality.

Features of single.Circuit devices

The boiler with one contour is intended only for heating the room and is usually placed where water heating is solved in some alternative way.

The module is equipped with a closed combustion chamber, and during the operation the flame of the boiler is enriched with oxygen coming from the room where the equipment is placed. The materials worked out during combustion are diverted through the vertical chimney specially equipped for this purpose.

Using gas boilers on cylinder gas

Currently, natural gas is the most optimal fuel for heating the house. The only negative. It is not always possible to connect the heating system to the main gas pipeline. In this case, you can pay attention to an alternative in the form of liquefied gas. Boilers using cylinder gas in our country are not uncommon.

Classification

Liquefied gas boilers are single.Circuit and double.Circuit. A single.Circuit boiler is intended only for heating, while a dual.Circuit is capable of heating the house and ensure hot water supply in it.

Consumers are offered wall, floor gas boilers with open and closed combustion chambers. In addition, you should pay attention to the power of this heating device. A variety of modifications often complicates the choice of the user, so you should dwell on the most important characteristics in more detail.

Pressure

For liquefied gas boilers, the ability to function at low pressure is fundamentally important.

The constant supply of the cylinder gas will be carried out at a pressure of 3-4 mbar. Therefore, when choosing a boiler, you should pay attention to this parameter.

Efficiency is one of the most important parameters of the heating system. Liquefied gas is more expensive than the mainstream, and the cost of transportation should be added to its cost.

Therefore, when buying a boiler, you need to calculate the consumption of cylinders, taking into account the effectiveness of the entire heating system.

Efficiency of modern serviceable equipment can reach 90-95%. To calculate the gas consumption for heating, you need to know the total area of ​​the room: 10 kV.M is spent about 1 kW of power.

For heating and heating of water in a country house in 100 square meters.M will require about 2 cylinders per week and 8-9 cylinders per month. You can connect the cylinders into the group: according to the rules, it is allowed to use the cylinder system up to 15 pcs. In this case, gas containers should be in a closed metal cabinet.

Installation equipment

To install the heating system, you will need:

Ballon gas burners are distinguished by their configuration from ordinary ones, and are usually included in the standard equipment of gas boilers. If necessary, they can be purchased separately. Controversial reinforcement and necessary gearboxes can be bought from a company or directly at the stations of cylinder gas station.

Connecting

A cylinder or group of cylinders is connected to a boiler through a gearbox with a bandwidth of about 2 m3 /h. Gearboxes for home plates are designed for lower throughput. They are not suitable for the heating system. The gas tank system can have one common gearbox or a separate regulator for each cylinder. The second option is more costly, but it is recommended by the masters. Individual gearboxes ensure maximum safety.

Liquefied gas cylinders cannot be installed on the street: the cold will provoke a pressure reduction, and the heating pad may refuse to work. An ideal place for installation is a warm, ventilated room. It is important to remember that the cylinder gas is heavier than the air, and in the case of leakage it will accumulate in the lower part, increasing the likelihood of an explosion. Therefore, the room should be chosen separately from living rooms. It should not have basements and underground!

Gas cylinders are connected to the boiler burner using a metal corrugated pipe. This reduces the likelihood of gas leaks due to vibrations of the system.

Expandation adjustment

Using automatic sensors and correct settings, you can reduce the norms of propane consumption by 3-4 times. If we are talking about a country house, then the gas consumption will be even less: for the period of the absence of people, the automation will maintain a temperature at the level of 6-9 ° C, which will reduce propane consumption to 0.7-0.8 cylinders per week. Liquefied gas heating is not the cheapest option, but in some cases it is the most optimal if there is no problem of delivery of cylinders.

The gas boiler perfectly performs its functions when connecting to the main gas pipeline. In this case, it is quite easy to switch the equipment to a constant source of fuel supply. Just change the burner.

But if there are no prospects for connecting the building to the gas pipeline, you should once again calculate the feasibility of installing a gas boiler. For a house with a total area of ​​more than 100 m2 and maintaining a temperature of about 25 ° C, it is worth considering the possibility of installing a solid.Fuel boiler or another heat generator and heating water.

Refueling

Cylinders every 3 year undergo mandatory certification. This is necessary for the user’s own security. Such containers can serve about 10 years. The standard house consumes about 10-12 cylinders per month, so you will have to refuel them weekly-you cannot transport more than 3 cylinders at a time without a special resolution.

Before refueling, the vessels need to be prepared. To do this, you need to remove condensate, which artificially reduces useful volume and harms the steel walls. Removing condensate. The prerogative of specialists, carry out such work with your own hands. Always risk.

If the master is hard to find for some reason, then you will have to carry out the procedure on your own. The cylinder is taken to the open space without sources of fire, grounded and then removed the gearbox. Leave for 2 hours in order to disappear the remnants of gas.

After a two.Hour downtime, the vessel turns over, and the water flows into the ground. Can be taken to a gas station.

It is worth choosing a tanker who organizes both transportation and work guarantee. It is better not to contact the automobile stations, because their equipment does not have a special cutter, which regulates the filling of household cylinders with gas. They also do not have a special connector for connecting the cylinder to station equipment.

Choose a boiler on liquefied gas

An important criterion is the power measured in kW. Heated area, as a rule, 9-10 times more than this value. That is, choosing a boiler with a capacity of 11.3 kW, you will reproduce a room with an area of ​​about 100 m2.

However, it is necessary to make an amendment to the fact that with prolonged and severe frosts, the equipment of such power will not be able to maintain a given temperature. Therefore, experts recommend choosing a boiler unit with a margin.

Gazgolder for heating on propane

It is a hermetic capacity of a large volume with the system of receiving and transmitting propane. Gazgolder can be installed on the surface or underground. In the latter case, only the cover of the operational hatch will be visible. This design will provide a large volume of gas for heating not only garage on propane, but the whole house.

For its installation, the following conditions must be met:

  • The minimum distance from the Gazagolder to the foundation of the house is 10 m;
  • The outer line should have safety elements, while it is necessary to use special pipes for gas transportation;
  • When planning heating a house with a propane using a gas tank, ways of entering the gas station for a car are provided;
  • To perform self.Filling the container is prohibited. To do this, use the services of a specialized company.

The advantages of using the gas tank include a long service life of structures. It is also recommended to select a container of such a volume that the refueling is carried out once within 2-3 years. Compared to the cylinder heating which method of storage of propane is more expensive. This is due to the initially high cost of equipment and the cost of its maintenance. To reduce them, two or three houses can be connected to one gas tank.

Proper use of gas cylinders

The containers for storing and transporting liquefied gas should undergo annual verification if they are constantly operated, if only in the heating season. 1 time every 2 years.

Cylinders cannot be installed both in basement and basement. Where the cylinder will be installed, a whole floor should be mounted, without cavities, and free space. This requirement is due to the fact that the gas is heavier than the air, and with the insufficient tightness of the system, its accumulation leads to the possibility of an explosion.

Capacities should not be operated in an inclined position or lying. Only vertically, having previously fixed it with the wall with a special clamp. The clamp prevents the random fall of the capacity. So that the cylinder can be checked or quickly replaced, it should be installed separately from the main equipment. Near the product used, for better practicality, you can mount fasteners for spare containers.

Four gas cylinders with a capacity of 50 liters and a gas.Tank installation are placed in the street cabinet. With a closed cabinet, an accidental fall of cylinders is excluded

Details about the cabinets for cylinders are described in the video below.

Gas.Ballon equipment in cars and private houses is identical, and when operating it should be guided by the basic rule. Not to fill out the cylinder in full. For products that are filled by more than 90 %, the operational period is sharply reduced, and the possibility of an explosion is increasing.

transfer, boiler, propane

Gas cylinders should not be left under direct sunlight. Gradual heating of the outer surface of the product can also lead to explosion.

Using the heating system in the house built on the use of gas cylinders, one must not forget about the periodic maintenance. Usually, users try to do it before the heating season, or immediately after its end.

Alternative heating gas from cylinders: make the right choice

If you have a boiler for heating, which works on propane, then the consumption of the gas necessary for it is definitely very difficult to determine. Often this indicator depends on the method of insulation of the room. If the winter is severe, then the figure, of course, will grow. If you insulated your house well and there are no fierce frosts outside the window, then you will use gas with great savings.

Fuel consumption by a gas boiler working on propane will delight you much more than you would have to pay for heating the same house with the help of electricity. The use of trunk gas is considered the most economical, but it will not always be possible to connect to the general centralized gas supply system. In this case, heating the room with a boiler working on propane will be the most reasonable idea. When buying an unit for heating, you will definitely ask users reviews, consult with specialists, and ask consultants to give you a full description of the device and the possibility of its re.Equipment for liquefied cylinder gas. Before you finally make a decision, in favor of installing gas equipment, be sure to carefully weigh all the important arguments, calculate the fuel consumption, and only then proceed to the installation actions.
