Background

The boiler is an energy conversion device, the energy input to the boiler comprises chemical energy and electric energy in fuel, and the boiler outputs steam, high-temperature water or an organic heat carrier with certain heat energy. The boiler is a water container heated on fire, a furnace is a place where fuel is combusted, and the boiler comprises a boiler and a furnace. The hot water or steam generated in the boiler can directly provide heat energy for industrial production and people life, and can also be converted into mechanical energy through a steam power device, or the mechanical energy is converted into electric energy through a generator. The boiler for providing hot water is called a hot water boiler and is mainly used for life, the boiler is simultaneously carried out on a boiler and a furnace, and after water enters the boiler, the boiler heating surface in a steam-water system transfers absorbed heat to the water, so that the water is heated into hot water with certain temperature and pressure or generated steam, and the hot water or the generated steam is led out for application. In the combustion equipment part, fuel is combusted to continuously release heat, high-temperature flue gas generated by combustion transfers the heat to a boiler heating surface through heat propagation, the temperature of the high-temperature flue gas is gradually reduced, and the high-temperature flue gas is finally discharged from a chimney.

Flue gas is a mixture of gas and smoke dust and is the main cause of atmospheric pollution in residential areas.
