| Abstract: | The structural design and distribution of wind caps in air distributor of circulating fluidized bed(CFB) are closely associated with the jet characteristics of air out of the wind caps in dense phase zone.The real bed material for CFB boiler was used in a visible cold-state experimental platform to research the jet characteristics of air out of different-diameter small hole in dense phase zone.The definition of jet range of air out of small hole in dense phase bed material was put forward and verified.The e... |
