Through test and analysis, the influence of putting auxiliary air of the double inlet and double outlet coal pulverizer into operation upon ecomomic behavior of the boiler for 300 MW unit in one power plant has been obtained.

• 摘要通过试验分析了某电厂300mw机组锅炉所配双进双出钢球磨煤机辅助风投运对锅炉排烟温度的影响，结果表明，锅炉运行期间只要磨煤机一次风管不堵管，就无需投入磨煤机辅助风，辅助风仅在启动前和停磨煤机后吹扫管道时投入即可。
