兖州矿业(集团)公司铁路运输处开展了锅炉运行负荷和过量空气系数对烟尘排放浓度影响的分析,对此类问题的进一步研究有一定的参考作用。烟尘浓度是随着负荷率的增加而直线上升的。不同的锅炉要求炉膛内的过量空气系数是不同的。除了炉膛过量空气系数外,还有过热器、省煤器等处的过量空气系数,在排烟处测到的过量空气系数实际上包括锅炉鼓风量、锅炉各部、除尘器及管道 Yanzhou Mining (Group) Company Railway Transport Department to carry out boiler operation load and excess air coefficient on the impact of dust emission concentration analysis, further research on such issues have some reference. Soot concentration increases linearly with load factor. Different boilers require that the excess air ratio in the furnace is different. In addition to the excess air ratio in the furnace, there is excess air coefficient at the superheater, economizer, etc. The excess air coefficient measured at the smoke exhaust actually includes the amount of air blown by the boiler, the boiler ministries, the precipitator and the piping
