Gas generator is a production equipment that converts coal into flammable gas - gas (main components are CO, H2, CH4, etc.). The working principle is: after screening the coal that meets the gasification process specifications, the coal is added to the gas furnace by a stoker, and a mixture of self-produced steam and air is blown from the bottom of the furnace as a gasification agent. Coal undergoes sical and chemical reactions in the furnace to generate flammable gases. It is widely used in various thermal furnaces such as steel rolling furnaces, annealing furnaces, forging furnaces, steel tube furnaces, glass furnaces, aluminum melting furnaces, copper furnaces, and ceramic building furnaces. Various furnace shapes within the required temperature range.
