Flow field measurement of three-passage combustion facility for cement pit

This paper introduces the test that was carried out in CARDC about the flow field measurement of three-passage combustion facility for cement pit.The results show that the attenuation law of the axis direction velocities of jet in the three-passage jetting coal pipe is reasonable,which can be used to analyze the inflow characteristics of combustion facility;The new jetting coal pipe designs reasonably.It is a better parameter that the ANGEL of WHIRL BLADE (AWB) is 45° for the new jetting coal pipe.
