350MW等级超临界机组氨区扩容改造方案探讨

近十年,国内对电站锅炉燃煤污染物的控制进行了大量工作,为了脱除烟气中的NO,,在工业生产中作为N0*重要排放源的燃煤电站锅炉均配备了SCR脱硝装置。由于还原剂制备系统是SCR脱硝装置的重要组成部分,因此本文针对液氨还原剂将重点介绍其制备系统如何增容与扩建。

Investigation on the capacity expansion and reconstruction scheme of ammonia area in the supercritical pressure unit with 350MW level

In the past decade,a large amount of work has been done on the control of the coal-fired pollutants in power station boilers.In the industrial production,the coal-fired power station boilers,as an important source of NOX emission,are equipped with the SCR denitrification devices to remove the N0x in the flue gas.Since the reductant preparation system is an important branch of SCR deni・trification equipment,the main emphasis in this paper is on how to increase the capacity and expand the construction for the preparation system aimed at the liquid ammonia reductant.
