Measurement of Dense-Phase Bed Height in CFB Boiler Based on Flame Image Processing Technique

摘要：

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 exactly in furnace. The monitoring equipment, the flame image processing theory of recognition algorithm, and the choice of the threshold value of gray, are introduced in the paper. This image processing technique can provide CFB boiler with the safe, economic and clean operation in practical industry application.
