摘要

为解决现阶段常规垃圾焚烧电站污染物排放高、能量利用率低、初始投资成本高等问题，结合燃煤电站机组绿色转型发展需求，提出了燃煤锅炉耦合垃圾发电技术思路，搭建了30t/d燃煤锅炉耦合垃圾发电中试试验系统，采用热风、烟气及汽水3种耦合方式实现了垃圾在大型燃煤锅炉上的高效清洁处置，并针对系统运行对燃煤锅炉效率、污染物排放的影响以及垃圾处理能量利用效率进行了分析研究。研究结果表明：3种耦合方式对于实现垃圾的高效、清洁燃烧是完全可行的；热风耦合可提高垃圾焚烧处置效果，降低飞灰及大渣含碳量；烟气耦合能够保证常规污染物SO_2、NO_x及粉尘达到燃煤电站机组排放水平，且不会增加锅炉机组二噁英排放；汽水耦合能够提高垃圾焚烧能量利用效率。该技术的提出为我国垃圾等有机固废的处置提供了新的技术路线，具有广泛的应用前景。

Abstract

In order to solve the problems of high pollutant emission mass concentration

low energy utilization rate and high initial investment cost of conventional waste disposal power station

combined with the green transformation development needs of coal-fired power station. This paper proposes the technical ideas of coal-fired boiler station coupled with waste. A 30 t/d coal-fired boiler station coupled waste was built to analyze and study the impact of system operation on the efficiency of coal-fired power station

pollutant emissions and energy efficiency of waste disposal. And this paper uses three coupling methods of hot air

flue gas and steam water to achieve efficient and clean disposal waste on large coal-fired power station. The results show the three coupling methods are completely feasible to achieve efficient and clean disposal waste. The coupling of hot air can improve the effect of disposal waste and reduce the carbon content of fly ash and slag; the coupling of flue gas can ensure conventional pollutants such as SO_2

NO_x and dust reach the emission level of coal-fired power station without increasing the emission of dioxins. The coupling of steam water can improve the energy efficiency of disposal waste. This technology provides new technical ideas for the disposal of organic solid waste and has a broad application prospect.
