GAO Yuan;GAO Jinhao;Nanjing Ruilin Environmental Protection Technology Co.,Ltd.;
The drawbacks of the current denitrification unit are analyzed,and the solid urea direct injection SNCR denitrification technology is proposed.The comparison between the solid urea direct injection SNCR denitrification unit and the conventional SCR unit,and the economic benefit from the application of the two units has been carried out.The results show that the solid urea direct injection SNCR denitrification unit has the advantages of low investment and low total operation cost. The technology can be applied not only in thermal power plants,also the cement industry which usually generates basic soot,and the glass industry.
