The gas solid interaction was studied, the solid concentration and particle size distribution contours downstream of the nozzle were obtained. The particle roping mechanism in a coal conveying pipe with large diameter was also studied with the fiber probe. The on-line coal concentration measuring facility is needed for NO〓 reduction. In this work, a set of on-line coal concentration measuring facility was developed and installed in the coal conveying pipes of a 660MW capacity utility boiler, which can give on-line accurate coal concentration information for the operator.
