The coking process of the CO combustion energy recovery system in the coking unit of Taizhou Petrochemical usually exhausts exhaust gas at about 300 ℃. The exhaust gas temperature is reduced to below 120 ℃ by setting up a low-pressure waste heat boiler or air/gas preheater.

Waste heat power generation is mainly used in dry quenching waste heat power generation, sintering machines and cooling machines, cement kilns, glass kilns, and sulfuric acid projects.
