Research on Industrial Waste Heat Recovery and Multi-energy Coupling System

Aiming at the demand for efficient energy utilization and energy saving and carbon reduction in the industrial field, this paper investigates the synergistic mechanism of waste heat gradient utilization and multi-energy coupling system under the framework of thermal management through case studies in the iron and steel and chemical industries, and puts forward a heat recovery scheme based on the coupling system to realize a more efficient and energy-saving recycling and utilization of industrial waste heat. In the future, it is necessary to promote the development of waste heat recovery towards integration and low-carbonization through intelligent control, efficient material research and development and policy support, so as to provide technical support for industrial energy transformation.
