International ClassF22B 001/00Foreign Application Priority Data1991-01-15 SEAbstractDistributor device comprises at least one lower and/or one upper stationary distributor device for distribution of fuel in the form of gas and particles in a fluidized bed and is arranged above fuel feed nozzles in the bed, or at or above the upper limit of the bed. The task of the distributor device is to spread fuel, rising upwards in the bed, more evenly over a large area in the bed and to create turbulence above the bed. This is achieved by designing the distributor device with a mid-portion and upwardly-inclined wing-like members or the cone to bring about even distribution of fuel by forcing the fuel to follow an outwardly-directed horizontal or obliquely upwardly-rising flow of fuel. | |
