Volume Concentration and Phase Distribution Measurement of Pulverized Coal in the Pneumatic Conveyor

Abstract:

This paper proposed the design and experimental evaluation of a radiometric instrumentation system which was developed for measuring the volume concentration and phase distribution of pulverized coal in a pneumatic conveying pipeline.The system employed point γ-ray source with 180° plane angle of emergence source collimator, γ-ray detector multi-element independent each other annular arrayed out of the sensor conduct wall,every detector element was standardized singly,in order accommodate the inhomogeneity of the pulverized coal distribution in the pipeline.the instrument system would be able to determine the volume concentrition independently of the flow pattern while obtain the distribution information of pulverized coal in the conveying pipeline cross section. The static experment improved that the solution was correct in principle.
