摘要
为了从烟道中取得有代表性的烟尘样品 ,需等速采样。在使用普通型采样管时 ,为了满足采样现场的要求 ,应有一个与之相适应的等速采样流量近似计算公式。本文在《空气和废气监测分析方法》中烟尘等速采样公式的基础上 ,进行了化简、近似等计算 ,得到了几个可用于不同情况下的简化式 ,计算简便、迅速 ,适合于采样现场使用。
It is necessary to have an equi-speed sampling for getting a representative soot sample from flue.When using a common sampling tube,a formula for approximate calculation of the flow in the sampling tube is needed to meet the request of equi-speed sampling.In this paper,some simplified formulas suitable to different conditions are presented based on the formula in Measuring and Analysis Methods of Air and Exhaust Gas.These formulas have the advantage of simple and quick calculation,and are easy to use in field.
