垃圾焚烧余热驱动ORC发电系统的循环工质优化选择

摘要

垃圾焚烧余热利用不仅有助于降低能源消耗，还能实现固体废弃物处理与能源回收的双重目标。在有机朗肯循环（ORC）发电系统中，循环工质的选择是决定能量转化效率与系统经济性的关键环节。通过对不同循环工质的热力学性能、环境友好性及运行稳定性进行比较，可以发现合理的工质优化能够显著提升垃圾焚烧余热的发电效率，并兼顾设备安全与寿命。本文以垃圾焚烧余热特性为基础，结合ORC系统运行需求，探讨工质优化选择的原则和评价方法，提出适合的工质匹配策略，为垃圾焚烧余热驱动的高效清洁发电提供参考。

Abstract

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.
