摘要

针对垃圾焚烧电厂能量利用率低及余热潜力未被充分挖掘问题，引入余热梯级利用技术，提出一种考虑垃圾电厂与余热梯级利用技术的综合能源系统减碳协同优化模型。首先，构建含垃圾电厂的系统框架，分析垃圾电厂电热气联产可行性，构建电厂能流关系模型，并对渗滤液厌氧处理过程进行数学建模。其次，引入余热梯级利用技术设计余热回收系统，对底灰固体高温颗粒设计超临界 CO2布雷顿循环系统进行余热回收。然后，通过碳核算模型计算碳排放量并结合碳交易机制限制碳排放，建立以系统总运行成本最小化为目标函数的综合能源系统减碳协同优化模型。算例分析结果表明该模型不仅降低了购能成本和对外能源依赖程度，还实现了减碳效果，有效证明模型具备经济-环保效益。

Abstract

In response to the problem of low energy utilization and under-exploitation of waste heat potential in waste-to-energy plants

a carbon-reduction coordinative optimization model of the integrated energy system considering waste-to-energy plants and waste heat cascading utilization technology is proposed by introducing waste heat gradient utilization technology. Firstly

the system framework of a waste-to-energy plant is constructed

the feasibility of combined electricity

heat and gas production in waste-toenergy plants is analyzed

the energy flow relationship model of the plant is constructed

and the anaerobic leachate treatment process is mathematically modelled. Secondly

waste heat recovery system is designed by introducing waste heat cascading technology

and a supercritical CO 2 Brayton cycle system is designed for waste heat recovery of solid high temperature particles of bottom ash. Then

carbon emissions are calculated through a carbon accounting model and combined with a carbon trading mechanism to limit carbon emissions

and a coordinative optimization model for carbon reduction of the integrated energy system is established with the minimization of total system operating costs as the objective function. The numerical analysis results show that the model not only reduces the cost of energy purchase and external energy dependency

but also achieves carbon reduction

effectively demonstrating the economic and environmental benefits of the model.
