摘　　要：介绍了限流孔烟气采样器的设计原理、主要技术指标、设计指标说明及采样器的主要性能。通过测定SO2标准气体和比对试验，表明限流孔烟气采样器控制流量稳定，计量采气体积准确，应用结果满意。The design principle,the main technical indices,the specification of design indices and the ~ pro~ Of the stact gas sampler with critical orifice are described in the paper. Through experiments with determining the standard gas of SO2 and comparing with other instrument,it shows that the stact gas sampler controls the rate of now steadily and calculates the volume of gas accurately,Th result of application is satisfying.
