摘　　要：针对某公司2号锅炉由烧贫煤改为掺烧烟煤后出现的制粉系统"放炮"(爆炸)、主蒸汽温度偏低、SCR反应器入口烟气氮氧化物含量高等问题,采用制粉系统掺混低温炉烟技术,有效解决了上述问题,提高了制粉系统的安全性和机组的经济性、环保性,达到了预期目的。In order to solve the problems occurring after No.2 boiler burning lean coal instead of bituminous coal,such as pulverizing system"blasting"(explosion),low temperature of main steam and high content of nitrogen oxides in flue gas at the entrance of SCR reactor,the company adopts the technology of mixing pulverizing system with low temperature furnace flue gas",which improves the safety of pulverizing system,the economy and environmental performance of the unit.

关 键 词：低温炉烟 制粉系统爆炸 氮氧化物 主汽温度
