摘要:

随着环保排放指标的提高,原有火电环保设施已经无法满足新的污染物排放限值,需要对环保设施的供/配电系统进行增容改造。环保岛电源的引接方案是改造的重点研究方向之一。通过对比、分析某电厂环保岛电源引接方式和脱硫系统改造方案,给出了合理的改造技术方案。

Abstract:

With the improvement of the environmental emission index, the original environmental protection facilities of thermal  power plants have been unable to meet the requirement of new pollutant emission limits. Retrofitting on power supply and power distribution system has to made for environmental protection facilities, in which the power supply connection scheme for the simultaneous removal of multipollutant system(SRS) becomes the main research area. Through the comparison and analysis on power supply scheme for SRS and the retrofitting scheme for desulfurization system,a reasonable technical scheme was given.
