国电泰州电厂2×1000MW二次再热机组NOx、SO2超低排放技术应用
Applications of NOx and SO2 Ultra-Low Emission Technologies for the 2×1000 MW Double Reheat Units in Guodian Taizhou Power Plant
摘要
Abstract
In order to realize the ultra-low emission of NOx and SO2 in the flue gas,the eddy-mixing technology and the single tower with dualloop desulfurization technology are used in the SCR de-NO.x system and the flue gas desulfurization system respectively in the 2×1000 MW ultra-supercritical coal-fired generating units of Guodian Taizhou Power Plant Phase Ⅱ Project.In this paper,the principles of the eddy-mixing technology and the single tower with dual loop desulfurization technology are introduced,and the design scheme and the implementation effect of the flue gas desulfurization and denitrification of the units are presented as well.The practical results show that by adopting these two technologies,the ultra-low emission of NOx and SO2 in the flue gas has been achieved with the removal effieiencies of 90.3％ and 99.6％ and the emission concentrations of 31 mg/m3 and 15 mg/m3,respectively,which are far below the national ultra-low emission limits,and even better than the emission level of gas turbines.关键词
