火力发电厂300MW机组烟气脱硫方案选择

THE SELECTION OF FLUE GAS DESULFURATION PROGRAMS OF 300MW UNIT THERMAL POWER PLANT

火电厂排放的二氧化硫已严重危害人类生存环境,我国把解决烟气脱硫问题纳入国家大计之中,强制要求火电厂必须安装烟气脱硫装置,但是,烟气脱硫的关键技术和设备要靠进口,这样,一方面造成巨额资金外流,另一方面又会因备品备件问题影响生产,为此,文章分析了火力发电厂烟气脱硫多种工艺方案、技术市场现状和目前设备供货情况,结合实现国产化烟气脱硫技术和设备是今后的必然发展方向等。对主流烟气脱硫工艺方案进行了分析和比较,根据技术成熟可靠、运行业绩和实现国产化、降低投资及运行费用、维护方便等原则,认为300MW机组工程烟气脱硫方案应选择石灰石-石膏湿法烟气脱硫方案。

The technique programs of flue gas desulfuration of thermal power plant,status quo of technological market and current e- quipment supply situation are analyzed,it points out that development direction of domestic flue gas desulfuration and equipment.The princi- pal technique programs of flue gas desulfuration are analyzed and compared.According to principles of reliable and ripe technology,operation records,domestic product,low investment and operation cost,convenient maintenance,it believes that programs ...
