摘要
文章阐述了不同蒸汽参数机组的应用现状,分析了主蒸汽压力增加对锅炉、汽机等的影响,介绍了两种典型的垃圾焚烧发电超高压机组系统配置方案,分别是中温超高压机组的炉内再热、中温超高压机组的炉外再热方案.将两种方案进行了技术及经济性对比,同时以(2×750)t/d规模的炉排炉垃圾焚烧项目为例,与普通中温中压、中温次高压、中温超高压方案进行了对比.通过各种方案的技术经济对比分析,为垃圾焚烧电厂选择蒸汽参数及再热方案提供了参考.
Abstract
This paper expounds the application status of units with different steam parameters,analyzes the influence of the increase of main steam pressure on the boilers,steam turbines,etc.,and introduces two typical configuration schemes for waste-to-power super-high pressure unit system,which are the reheating inside the furnace of medium temperature super-high pressure unit and the reheating outside the furnace of medium temperature super-high pressure unit.The technical and economic comparison of the two schemes is carried out.At the same time,the(2×750)t/d grate furnace waste incineration project is taken as an example to compare with the ordinary medium temperature medium pressure,medium temperature sub-high pressure and medium temperature super-high pressure schemes.Through the technical and economic comparative analysis of various schemes,it provides a reference for the selection of steam parameters and reheating schemes for waste incineration power plants.
