A large amount of lowtemperature waste heat generated in the industrial production process dissipates in the atmosphere through flue gas and cooling media. Recovering and utilizing such heat is of a great significance for improving energy efficiency and promoting the achievement of "dual carbon" goals. With a detailed review of cases of utilization of lowtemperature waste heat by existing factories, this paper compares heat exchange schemes and energy conservation effects under different heat source conditions, deriving that lowtemperature waste heat has a wide range of applications from waste heat heating, raw material preheating and antifreezing, waste heat refrigeration to waste heat power generation. It is pointed out that when utilizing lowtemperature waste heat resources, attention should be paid to heat source characteristics and factory needs and utilization approaches adapted to enterprises should be selected. Further, this paper also presents a prospect of the important effect of lowtemperature waste heat in energy conservation and emission reduction.
