This paper proposes a method to measure the dense-phase bed height by edge-detection of Charge Coupled Device based on flame image processing technique in Circulated Fluidized Bed (CFB) boiler. The detection system was installed in a 480t/h CFB boiler, image processing model has been built,and in-situ experiment was carried out. Real-time bed height is reliable and meets the bed pressure drop exac...Show More
