略谈火电厂无旁路烟气脱硫脱硝系统电气一次设计

A Brief Discussion on the Electrical Primary Design of Flue Gas Desulfurization System without Bypass in Thermal Power Plant

在城市化进程的推动之下,我国生态文明建设日益推进,脱硫系统在火力发电中占据着关键地位,尤其是火力发电厂的日常运作过程中,烟气脱硫装置需要和主机组同时投运工作。加强对烟气中有害物质的处理,使其达到国家和行业相关标准,可以改善当前大气环境,协调经济发展与环境保护之间的关系。本文分析了有旁路烟气脱硫电气系统及无旁路烟气脱硫电气系统的特点,提出无旁路烟气脱硫电气系统的设计原则,探索无旁路烟气脱硫电气系统的设计方法。

With the promotion of urbanization,the construction of ecological civilization in China is advancing day by day,and the desulfurization system occupies a key position in thermal power generation,especially in the daily operation of thermal power plants,the flue gas desulfurization unit needs to be put into operation at the same time as the main engine group.Strengthening the treatment of harmful substances in flue gas to meet the relevant national and industrial standards can improve the current atmospheric environment and coordinate the relationship between economic development and environmental protection.This paper analyzes the characteristics of FGD electrical system with bypass and without bypass,puts forward the design principle of FGD electrical system without bypass,and explores the design method of FGD electrical system without bypass.
