The principle of operation of a coal boiler

How to heat a solid fuel boiler with coal? The coal boiler is an extremely simple installation, divided into two compartments. The first is a firebox, where they put the fuel. At the time of its burning, ash and slag are released that fall into the lower compartment.

How to heat the boiler with coal in the house? Modern models are often equipped with automation, through which the consumer can activate the autonomous operation of the furnace or control traction.

Which coal can be used

Coal is a plant product. It includes carbon and non-combustible impurities. Of these, ash and slag are formed during combustion.

Today, several types of coal can be distinguished. The youngest is lingitis. Its structure is quite loose, and you can break a piece with a light effort of the hand. Presented coal is usually used in thermal power plants. But for the kindling of residential buildings, this option, alas, will not work.

In addition to lingitis, there is also brown coal, as well as an option such as anthracite. They vary in humidity. In brown, she stopped at around 50%, and in anthracite, this figure does not exceed 7%.

And that is why anthracite will be the best option for the heating of a domestic boiler. In the combustion process, a little ash is released, which on the positive side affects the efficiency of the heater.
