摘要
本文通过对烟气测试中流速计算公式的比较分析,结合实际监测数据处理,认为烟气流速计算中,使用通用公式与简化公式的误差,虽然与R_s和B_s有关,但主要误差来源于B_s。而R_s不必用精密仪器测出烟气中各组份后求算。只要用简易仪器测得烟气中的X_(o_2)和X_(sw)的百分含量,即可求出R_s近似值,用于烟气流速计算。
Through the comparision of flow velocity formulae in flue gas measurement and combining with monitoring data processing, it concludes that the main error comes from B_s even though errors caused by conventional formula or simplified one are related to R_s and B_s. R_s can be calculated approximately by Xo_2 and X_(sw) contents which can be measured with simple instrament.
