Bottled gas convector gas flow rate

The issue of heating a living room today is solved by a number of different devices that are unique in design and operating principle. So, when heating country houses and country houses, the best for gas consumption is a convector for bottled gas.

The operation of a gas convector on bottled gas is based on the phenomenon of convection - the process of transfer of internal heat to the environment by flows of liquid or gas.

What the device consists of

To understand the principle of operation of the unit, you need to know what structural details it includes:

1. Gas-burner. In it, the supplied gas is burned and the received heat is transferred to the heat exchanger;
2. Heat exchanger. Air masses get here and then heat up;
3. Control module. Here is the temperature control and regulation of the volume of gas supply;
4. Chimney or coaxial pipe. From here, combustion products are released into the external environment.
5. Body.

Principle of operation and distinctive features

Air heating in the convector occurs due to the movement of air masses inside the heat exchanger under the action of forced or natural convection. In general, the operation of a heating apparatus can be described as follows:

1. Gas enters through the line or the attached cylinder into the burner, burns and heats the heat exchanger;
2. Cold air coming from below into the heat exchanger is heated and discharged through a special window or fan;
3. An exhaust manifold delays the combustion products and releases them through the chimney or coaxial pipe to the outside. From here, oxygen is also supplied in the reverse order, which is necessary to maintain the combustion process.

All gas convectors are built on these principles.

Attention! Various technical solutions and the development of new design features are designed to improve the quality of work and expand the scope of this device.

The market for heating equipment offers a wide range of gas heaters that differ from each other in certain ways. When choosing a gas convector, you should pay attention to the following criteria:

1. Material of which the heat exchanger is made. The life of the unit as a whole depends on what material the heat exchanger is made of. The main materials are steel and cast iron. Models with a steel heat exchanger are cheaper than cast iron counterparts. This is due to the low resistance of steel to rust and the simplicity of the production process. Correct operation of the device with a cast-iron heat exchanger guarantees continuous operation for a period of 40-50 years.
2. The amount of heat released. You need to choose a convector from the calculation, which, on average, is 10 m² 1 kW of heat energy is required. The larger the area of ​​the room, the higher the value of the efficiency and the amount of heat generated should be.
3. Type of combustion chamber. There are two options for the combustion chamber: closed and open. Today, more preference is given to the closed type. The difference between closed and open is that in the first case, instead of a chimney, a coaxial pipe is used. It allows you to bring the products of combustion to the street and produce fresh air intake for burner operation. Such a technical solution significantly increases the cost of the device. In the usual version, instead of a pipe, a regular chimney is used, which removes carbon dioxide to the outside, and fresh air is supplied by ventilating the room.
4. Energy characteristics. The amount of heat generated during the combustion of natural fuels also depends on its composition and chemical properties. The greatest demand is liquefied propane gas.
5. Mounting method. By the method of installation, all models can be divided into floor and wall. The first type is characterized by increased weight, since they have a fairly voluminous heat exchanger. The wall-mounted convector weighs less compared to the floor, it takes up less space and develops power up to 10 kW.
6. Type of convection. The use of additional fans in the design increases the speed of propagation of warm air masses in the room. The principle of forced convection is triggered here, when the fans artificially move air inside the heat exchanger. With natural convection, the heating rate is low, however, the operation of the device is practically not audible, eliminating possible irritating sounds from hearing.
7. Automation of device operation control. Many modern gas convectors are equipped with electronic control devices. With their help, you can adjust the air temperature and set the desired heating mode.

Important! When choosing a gas convector before buying, be sure to check the chimney or coaxial pipe for serviceability. When checking, no visible mechanical damage or signs thereof should be detected.

The calculation of power and gas flow depends on many parameters and factors related to both the characteristics of the device and environmental conditions.

Power

There is a special formula that allows you to calculate the average power of a gas convector. It looks like this: P = k * S, where:

• P-power;
• k is a coefficient taking into account the type of system and operating conditions. Also called a correction factor;
• S is the area of ​​the room.

The value of k for balloon heating is taken as 0.1. If the only heat source in the room is a gas convector, then this value is 0.12. In checkpoints and infrequently visited rooms, the coefficient is 0.15.

Consumption

When calculating the gas flow rate, parameters such as:

• room size;
• mode of operation;
• thermal insulation.

So, for 1 kW of output power during convector operation, usually 0.11 m³ natural gas or 0.09 kg of bottled gas (in our case).

Important! If we analyze the calculations, it turns out that the energy consumption of electric convectors is much higher than the consumption of gas convectors that consume gas through special pipelines, which is their distinctive advantage.

However, the benefits of using bottled gas convectors are negligible in terms of energy consumption. Such devices are recommended to be used for autonomous provision of premises with heat.
