Abstract

Abstract: Discusses the optimization experiments for supercritical boilers,according to the distribution of NOX,we adjust ammonia system,reduce the amount of injecting ammonia,the distribution uniformity of NOX at SCR outlet is improved,ammonia escape concentration is reduced,the impact of ammonium hydrogen sulfate to the air preheater is reduced and denitrification efficiency is improved.

Key words: mmonia spraying optimization, NOx distribution, SCR, ammonia escape
