Waste heat refers to the sensible heat and latent heat that have not been rationally used in the original design of the energy-consuming devices of industrial enterprises that have been put into operation due to the limitations of factors such as history, technology, and ideas. It includes waste heat from high-temperature exhaust gas, waste heat from cooling media, waste heat from waste steam and wastewater, waste heat from high-temperature products and slag, waste heat from chemical reactions, waste heat from combustible waste gas and waste materials. According to the survey, the total waste heat resources of various industries account for about 17% to 67% of their total fuel consumption, and the recyclable waste heat resources are about 60% of the total waste heat resources.
