OI^2-SCR烟气脱硝技术及其工程应用

Engineering Application of OI^2-SCR Flue Gas Denitrification Technology

文章介绍了江苏苏源环保工程股份有限公司开发的具有自主知识产权的OI2SCR烟气脱硝技术在国华太仓2×600MW机组中的应用情况,以及为了实现锅炉系统与烟气脱硝系统的优化兼容,对空气预热器、引风机、烟道等主要设备进行的技术改造。OI2SCR烟气脱硝技术工程应用表明脱硝效率达到90%,残氨逃逸率小于3×10-6,SO2氧化率小于1%,工程总投资成本仅为国外的30%,工程建设周期缩短3~5个月。

OI^2 - SCR flue gas denutrufucation technology with intellectual property right was developed by jiangsu suyuan Environmental Protection Engineering Co.Ltd.This technology has been applied to 2 × 600 MW units of Guohua Taicang Electric power Co.Ltd.For realizing the option and compatibility of SCR with boiler system,the main equipment, such as air preheater,drafffan,duct etc.were renovated.OI^2- SCR flue gas denitification project of Guohua Taicang Electric Power Co.Ltd. indieates that, NOx removal ≥ 90%, ammonia slip 〈 3 × 10^ -6, SO2 oxidation 〈 10% ,the total capital cost is only 30% of foreign equipment and the constraction period is shorten by 50%.
