The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high temperature water or organic heat carrier with certain thermal energy.The original meaning of pot refers to a water container heated on a fire, and a furnace refers to a place where fuel is burned. A boiler includes two parts: a pot and a furnace. The hot water or steam produced in the boiler can directly provide the required heat energy for industrial production and people's lives, and can also be converted into mechanical energy by a steam power device, or converted into electrical energy by a generator. Boilers that provide hot water are called hot water boilers, which are mainly used in daily life, but there are also a few applications in industrial production. The boiler that produces steam is called a steam boiler, often abbreviated as a boiler, and is mostly used in thermal power stations, ships, locomotives, and industrial and mining enterprises.

Boiler: It is composed of a boiler and a furnace. The upper water-holding part is the boiler, and the lower heating part is the furnace. The integrated design of the boiler and the furnace is called the boiler.Boiler is a kind of energy converter. It is a device that uses heat energy or other heat energy released by fuel combustion to heat working fluid water or other fluids to certain parameters.The boiler is divided into two parts: "boiler" and "furnace". "Boiler" is a pressurized part that contains water and steam, which heats, vaporizes, and separates water. "Furnace" is a place for fuel combustion or other heat release. It has combustion equipment, combustion chamber, furnace and heat release flue. Wait. Both the pot and the furnace are undergoing a heat conversion process, and the interface between heat release and heat absorption is called the heated surface. The boiler heats water into steam. In addition to pots and furnaces, there are auxiliary equipment such as frames, platforms, escalators, combustion, slag discharge, flue ducts, pipes, and furnace walls.The "Special Equipment Safety Law" defines equipment that uses various fuels, electricity or other energy sources to heat the contained liquid to certain parameters and provides heat energy in the form of external output media. The scope is specified as normal design Pressure-bearing steam boilers with water level greater than or equal to 30L and rated steam pressure greater than or equal to 0.1MPa (gauge pressure); pressure-bearing steam boilers with outlet water pressure greater than or equal to 0.1MPa (gauge pressure) and rated power greater than or equal to 0.1MW Hot water boiler; organic heat carrier boiler with a rated power greater than or equal to 0.1MW.
