烟气林格曼数监测新探

Discussion on the method of smoke's Ringelman number monitoring

讨论了烟气林格曼数在监测时间选择和计算取值方面存在的问题。认为在一个加煤燃烧周期内按一定间隔时间取值，然后取最大值与平均值之和的１／２作为监测结果有一定意义。并提出了一个表达方式，时间—林格曼数Ｂ＝１／ＴΣｎｉ＝１（Ａｉ×ｔｉ）。

This paper discussed problems in sampling time choice of Ringelman number monitoring and selection of value. A formulae A=1/2 ( A max +A ave ) is suitable for smoke monitoring cycle from coal was put into a boiler to next coal added. The author proposes 2nd formulae so called time- Ringelman number to solve problem in Ringelman number monitoring.
