Analysis For Sampling Tube’s Head of SCR DeNOx Reactor’s Inlet Flue

The sampling tube is always used to collect flue gas in the field of CEMS,However,the inlet of SCR DeNOx reactor system always with more than 300℃ , velocity comes to about 14m/s,as well as dust with high concentration.All these factors could reduce the life of sampling tube.In this paper,using software ANSYS to analyze the sampling tube.Resulting the dangerous areas,we could take some measures to extend the life of sampling tube.
