[0002] A boiler is an energy conversion device that uses the heat energy released by fuel combustion or other thermal energy to heat working medium water or other fluids to certain parameters. The fuel burns in the "furnace" and releases heat. This heat is transferred to the water or other working medium in the "pot" through the heating surface, raising the working medium temperature. When it reaches a certain parameter, it outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. For example, in a coal-fired boiler, coal burns in the furnace, and the high-temperature flue gas generated transfers heat to the water in the water pipe or boiler shell, turning it into steam or hot water.
