The utilization of waste incineration waste heat not only helps reduce energy consumption but also achieves the dual goals of solid waste treatment and energy recovery. In the Organic Rankine Cycle (ORC) power generation system, the selection of cycle working fluids is a key link that determines the energy conversion efficiency and system economy. By comparing the thermodynamic performance, environmental friendliness, and operational stability of different cycle working fluids, it can be found that reasonable working fluid optimization can significantly improve the power generation efficiency of waste incineration waste heat while taking into account equipment safety and service life. Based on the characteristics of waste incineration waste heat and combined with the operational requirements of the ORC system, this paper discusses the principles and evaluation methods for the optimal selection of working fluids, proposes suitable working fluid matching strategies, and provides a reference for efficient and clean power generation driven by waste incineration waste heat.
