Pulverized coal fineness detection based on double-D optical sensor
Abstract：Based on the theory that the received light of the high concentration particle group is mainly influenced by particle distribution, wavelength and refractive index, the functional relation between particle size and backscattering light intensity was studied. The double-D optical sensor was settled on the round roller, and how it detected the coal par- ticles＇ s screen residue was emphasized. After analyzing the detection data disposed by 1st order filtering algorithm, the results show that the particle group whose screen residue is large,its backscattering fluctuates severerly;when the screen residue turns small,the data become stable, and the detection data are linear with the particle group＇ s distribution.
