[0002] A boiler is a device used to heat water or produce steam, usually consisting of one or more burners, water pipes and gas pipes. The burner releases energy in the fuel (such as coal, oil or natural gas), transfers heat to water or other fluids, and turns it into high-temperature and high-pressure steam. This steam is then used in heating systems, factories or other purposes. Boiler waste heat reuse refers to the phenomenon that a large amount of heat generated during the combustion of fuels such as coal, oil or gas is not effectively utilized and is wasted after the boiler is finished working. This phenomenon will lead to energy waste and environmental pollution.
