火电厂“超洁净排放”改造应对策略研究及问题分析

The strategy research and problem analysis of “ultra clean emission”transformation for power plant

随着环保减排政策的不断收紧,火电企业进行"超洁净排放"改造势在必行。介绍了能够实现"超洁净排放"改造的可行性技术措施,并分析了改造特点及注意事项,涉及内容包括脱硝方面的低氮燃烧技术和低负荷投运改造方案、脱硫方面的增容改造方案和单塔双循环技术、除尘方面的湿式电除尘技术和高频电源技术。最后,对火电企业今后面临的热点问题进行了展望。

Along with the environmental policy tightening, the reform of ultra clean emission in thermal power en-terprise is imperative.The feasibility of the technology was introduced in this paper which can realize super clean emissions, the characteristics and the matters needing attention were also analyzed, including the low ni-trogen combustion technology and the reform project of low load operation in denitrification, the reform project of capacity-increase and the double dual cycle technology in desulfurization, and the wet electrostatic precipitator device technology and the high frequency power supply technology in dust removal.Final y, the hot problem in the thermal power enterprises facing in the future was prospected.
