Boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy in fuel, electric energy, heat energy of high-temperature flue gas and other forms. After boiler conversion, steam, high-temperature water or organic heat carrier with certain heat energy are output. It is mainly used in thermal power plants, ships, locomotives and industrial and mining enterprises.
