This paper analyzed the influence of SCR de-NOx equipment to the boiler system on theory. The problems are discussed such as the burning stability, furnaceimplosion and fan stability.
从理论上分析了SCR脱硝装置对整个锅炉系统的影响，包括稳定燃烧、炉膛内爆、风机的稳定性等方面。

The installation of SCR would lead to the increase of pressure fluctuation, do harm to the burning stability of the furnace, and give more chances to boiler implosion as well as induced fan surge.
