Title:
FLUIDIZED BED SYSTEM AND METHOD FOR OPERATING FLUIDIZED BED FURNACE
Document Type and Number:
WIPO Patent Application WO/2014/175208
Kind Code:
A1
Abstract:
A fluidized bed system equipped with: a main nozzle group (a first nozzle group) (144) provided within a fluidized bed furnace (130); an auxiliary nozzle group (a second nozzle group) (154) provided within the fluidized bed furnace; a first supply unit (160) that supplies gas to the interior of the fluidized bed furnace through the first nozzle group; a second supply unit (180) that supplies gas to the interior of the fluidized bed furnace through the first nozzle group and the second nozzle group; and a control unit (190) which, during a startup operation, controls the second supply unit to supply gas to the interior of the fluidized bed furnace, thereby forming a fluidized bed of a fluid medium in the fluidized bed furnace, and which, during a normal operation, stops the supply of gas by the second supply unit and controls the first supply unit to supply gas to the interior of the fluidized bed, thereby forming a fluidized bed of the fluid medium in the fluidized bed furnace.
