What is a steam boiler?

- Aug 22, 2019-

The boiler is an energy conversion device. The energy input to the boiler is in the form of chemical energy in the fuel, electric energy, heat energy of high-temperature flue gas, etc., and is converted by the boiler to output steam, high temperature water or organic heat carrier having a certain heat energy. .

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.

A steam boiler refers to an industrial boiler that heats water to a certain parameter and produces high-temperature steam. The water is heated into steam in the drum, and the heat is emitted from the furnace, which is the principle of the steam boiler. The steam boiler belongs to special equipment. The design, processing, manufacture, installation and use of the boiler must be supervised by the technical supervision department. The user can only use the steam boiler if he obtains the boiler use certificate.

According to the fuel (electricity, oil, gas), steam boilers can be divided into three types: electric steam boilers, fuel steam boilers, and gas steam boilers. According to the structure, vertical steam boilers and horizontal steam boilers can be divided into small and medium-sized steam boilers. The double-return vertical structure and the large steam boiler are mostly three-return horizontal structures.
