Abstract
Air distributor is one of the most important devices to maintain stable and high-efficient operation of circulating fluidized bed boilers. And the pressure drop of the air distributor determine the effect of air distribution and efficiency. The wind caps are the essential parts of air distributors, whose structures determine the pressure drop. Therefore, predicting the resistance of wind caps is one of the most important issues in CFB boiler design. At present, there is little study and theoretical inference about the pressure drop prediction when the diameters of internal structure change. In this study, cold-modelling experiments were made to study the flow characteristics and the resistance regulation as geometry parameters changes qualitatively.
