燃煤烟气低浓度粉尘排放测试的研究
Studies on low concentration of dust emission test in coal -fired flue gas
摘要
Abstract
The traditional testing method mentioned in GB /T 16157-1996 only apply to stationary source with more than 50 mg/m3 particulate concentration.Pol ution control technologies and processes are maturing with the strict emission standards, the online data of some demonstration projects show the emissions of particulate are less than 1 mg/m3 .There are often occurring weightlessness phenomenon if fol owing the traditional testing methods, thus it cannot get real concentration of dust emission in flue gas.Through repeated experiments and practice, the weightlessness problem can be effectively solved by using one-piece sampling-head and high flow sampling pump, increasing the sampling volume, reserving blank samples, choosing high-quality filter membrane and heating sampling gun, and the accuracy and reliability have been greatly improved.The method has been applied in practical engineering, provided reference for practical engineering.关键词
