What is a boiler? What is the boiler used for?

Boiler is an energy conversion equipment, is also one of the special equipment. The boiler works by other energy heating the water inside the boiler to produce hot water or steam. Here, other energy refers to the fuel of the boiler, such as gas combustion, oil combustion, coal combustion, etc., which is the energy required after combustion.
 

1, depending on the fuel, different fuels will lead to different boiler operating costs. Generally speaking, coal-fired boilers are very economical, but with the improvement of the environment, coal-fired boilers are banned. At present, the common boilers on the market are oil, gas, biomass boilers and electric heating boilers. However, electric heating boilers are expensive to run. For example, a ton of electrically heated steam boiler consumes 700 KWH of electricity per hour. Therefore, enterprise users considering electric heating boilers need to consider carefully. However, the main advantage of electric boilers is their high thermal efficiency and absolute pollution-free.

2, according to the use of boilers can be divided into steam, hot water and boiling water boilers. Hot water and boiling water boilers are common in our lives. Hot water boilers are widely used, such as winter heating, bathing, etc., which require hot water boilers, and boiling water boilers are usually used in schools and hotels. Boiling water boilers for direct drinking are usually electrically heated boilers. Steam boilers are mainly used for industrial needs.

3, it can be divided into vertical boiler and horizontal boiler according to the shape. The obvious difference between them is that one is a vertical boiler and the other is a horizontal boiler. Generally speaking, the vertical type is mostly a small boiler, and the horizontal type is a large boiler.

Boiler is a kind of energy conversion equipment, belongs to the pressure vessel. It is the working process of producing steam, boiling water, high temperature or hot water by transferring the heat energy to the water in the boiler after burning other chemical fuels to produce heat energy. As the name suggests, the boiler consists of a "pot" and a "furnace". The boiler is a water holding device, while the furnace is an combustion device, that is, the water contained in the boiler is heated by burning it in the furnace. In particular, what are the components of a boiler?

1, boiler composition:

There are many types of boilers, which can be subdivided according to fuel type, product type, working pressure, etc. The composition of different types of boiler products is different, but in general, its main components are two main parts, one is the main body of the boiler, and the other is its auxiliary machinery.

2, coal-fired boiler composition:

The coal-fired boiler consists of the main engine and auxiliary engine of the boiler. Auxiliary machinery includes cylinder (cylinder), blower, governor, induced draft fan, slag removal machine, coal loader, chimney, flue, electric control cabinet, water pump, water treatment, softening water tank, valve instrument, etc.

3. Composition of gas boiler:

The gas boiler is composed of the boiler main engine and the burner, and the auxiliary engine includes water treatment, auxiliary cylinder (auxiliary cylinder), computer control cabinet, valve instrument, chimney, energy-saving device, etc.

4, electric boiler composition:

Its auxiliary equipment includes computer control cabinet, sub-cylinder (sub-cylinder), valve instrument, expansion water tank, etc.

5. Composition of heat conduction oil furnace:

The auxiliary machine of heat conduction oil furnace is composed of circulating pump, fuel injection pump, filter, separator, chimney, control cabinet, expansion box, oil storage tank, valve instrument, etc.
