<p>Distributor equipment comprising at least one lower and/or one upper stationary distributor device (15, 16) for distribution of fuel in the form of gas and particles in a fluidized bed (5), which distributor device is arranged above fuel feed nozzles (13) 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, over a large area in the bed and more evenly distribute the fuel in the bed as well as to create turbulence above the bed. This is achieved by designing the distributor device with a mid-portion (19) or a mid-section (23) and, directed out from this mid-portion/mid-section, a distributor part in the form of obliquely upwardly-inclined wing-like members (17, 18, 21, 22) or an obliquely upwardly-directed funnel-shaped cone (30) or some other body where the wing-like members or the cone and the body bring about the mentioned distribution of fuel by forcing the fuel to follow an outwardly-directed horizontal or obliquely upwardly-rising flow of fuel, seen from the mid-portion/the mid-section.</p> |
