Abstract: With the rapid development of social economy, the status of energy conservation and environmental protection has
gradually improved. As a very typical secondary energy, waste heat is largely produced in industrial production. The use of key
technologies can realize the recovery and reuse of waste heat, and can effectively achieve energy conservation and emission
reduction. Based on the visual threshold of carbon neutrality, this paper summarized the characteristics of industrial waste heat,
and discussed the key technologies of industrial waste heat recovery and utilization in detail, hoping to provide a reference for the
development of industrial waste heat recovery and utilization technology.

Key words: carbon neutrality; industrial waste heat; heat exchange technology; heat power conversion technology; refrigeration
and heating technology
