<p>To a fluidized combustor bed (1) there is passed particulate fuel via a fuel flow distributor (8) which comprises a vessel (9) for receiving a particulate fuel from a fuel storage (10). The fuel is fed into the vessel (9) of the fuel flow distributor (8) from the fuel storage (10), whereupon the fuel is fluidized in a bed (14) above a bed bottom (15) in the vessel of the fuel flow distributor. The fuel flow distributor (8) comprises at least two feed pipes (7) with associated inlets (18) located adjacent the surface (19) of the bed (14) in the fuel flow distributor, where fluidization gas (16) which leaves the vessel (9) via a feed pipe (7) feeds out fuel to at least one nozzle (6) in the bed (1) of the combustor (2), extra gas (20) being supplied to the feed pipes (7) at the inlets thereof, such that the flow of fuel through an individual feed pipe (7) can be controlled by controlling the gas flow (20) supplied to the inlets of the respective feed pipe.</p> |
