The boiler is an energy conversion device. The energy input to the boiler is chemical energy and electric energy in the fuel. The boiler outputs steam with a certain heat energy, high temperature water or organic heat carrier.
The original meaning of the pot refers to the water container heated on the fire, the furnace refers to the place where the fuel is burned, and the boiler includes two parts of the pot and the furnace. The hot water or steam generated in the boiler can directly supply the required heat energy for industrial production and people's life. It can also be converted into mechanical energy by steam power plant, or converted into electrical energy by a generator.
The boiler that supplies hot water is called a hot water boiler, and is mainly used for living, and there are also a small number of applications in industrial production. Steam generators are called steam boilers, often referred to as boilers, and are used in thermal power plants, ships, locomotives, and industrial and mining enterprises.
