摘要
针对目前国内基于单个探头的单点在线测试烟气流量与参比方法监测比对合格率不高的问题,提出一种新颖的基于平均差压皮托管法的多孔流速仪,通过对不同的安装位置及安装数量的多孔烟气流速仪的烟气在线流量监测结果与手工监测结果进行比对,验证在适当位置安装一定数量的多孔烟气流速仪可以确保与手工监测比对结果满足要求。
Currently, pass rate of the monitoring of domestic single point measurement of flue gas flow monitoring system based on the single probe with the reference method monitoring is not high. The paper proposes a novel porous flue gas flow meter based on the average differential pressure of pilot tube method. The comparison of the results between manual monitoring and flue gas flow monitoring through different installation location and number of porous flue gas flow meter, verified that a certain number of porous flue gas flow meter installed in appropriate place could satisfy the requirements.
