[0002] A boiler is an energy conversion device. The energy input into the boiler includes chemical energy and electrical energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's lives, or it can be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator.
