The boiler that produces steam is called steam boiler, which is usually referred to as steam boiler for short. Electric steam boiler refers to a steam boiler that generates rated pressure by heating with power supply. Boiler is a mechanical device that uses the heat energy of fuel or other energy sources to heat water into hot water or steam. The original meaning of a pot refers to a container for holding water heated on a fire, and a furnace refers to a place where fuel burns. A boiler consists of two parts: a pot and a stove. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy by steam power devices or converted into electrical energy by generators. Steam boilers are mostly used in thermal power plants, ships, locomotives and industrial and mining enterprises.
