Applications and characteristics of BS-I pitot tube

Abstract

Abstract:

It is recommended by a standards of electric power that BS-I pitot tube is a measuring device that can be directly used in gas velocity in pulverized coal pipes. The correction of measuring based on the mass concentration of coal powders is not required and it is not easy to deposit ash. Insitu test on the BS-I pitot tube indicated that the measurement performance and accuracy are in line with expectations. Numerical computations with CFD were then conducted to investigate the BS-I pitot tube’s characters and the effect of relative attitude (rotation, inclination) and the degree of main pressure pipe to the velocity coefficient under measurement. The results showed that the measuring accuracy of BS-I pitot tube was insensitive to these factors.
