火电脱硝百度百科

火电脱硝是指火力发电为防止锅炉内煤燃烧后产生过多的NOx污染环境，应对煤进行脱硝处理。分为燃烧前脱硝、燃烧过程脱硝、燃烧后脱硝。即脱去烟气中的NOx（氮氧化物 2020年4月21日目前，我国针对烟气脱硝处理的措施主要分为：燃烧过程控制和燃烧后烟气脱硝技术处理两种。前者主要是以低NOx燃烧、燃烧优化调整、再燃技术等来控制。后电厂脱硝方法有哪些？知乎脱硝是指：燃烧烟气中去除氮氧化物的过程，防止环境主流的脱硝工艺：比较主流的工艺分为：scr和sncr。这两种工艺除了由于SCR使用催化剂导致反应温度比SNCR低外，其他并无太大区别，但如果从建设成本和运行成脱硝及脱硝系统介绍知乎2010年4月1日本标准适用于机组容量为200mw及以上火电厂燃煤、燃气、燃油锅炉同期建设或已建锅炉的烟气脱硝工程。机组容量200MW以下的燃煤、燃气、燃油锅炉及其他工火电厂烟气脱硝工程技术规范选择性催化还原法中华 2020年2月29日当机组负荷较低时,脱硝装置入口烟气温度可能低于催化剂的正常使用温度,导致脱硝系统无法运行,造成排污超标等环保问题。基于此本文就火电厂 (PDF) 火电厂全负荷脱硝技术探讨 ResearchGate
