FLOW RATE CONTROL UNIT AND CONTROL METHOD FOR CONTROLLING SOLID FLOW BETWEEN FLUIDIZED BED FURNACE AND CYCLONE, AND CIRCULATING FLUIDIZED BED BOILER INCLUDING FLOW RATE CONTROL UNIT AND OPERATING METHOD THEREFOR

WIPO Patent Application WO/2019/168211

A1

The present invention relates to a flow rate control unit and control method for controlling a solid flow between a fluidized bed furnace and a cyclone, and a circulating fluidized bed boiler including the flow rate control unit and an operating method therefor. More specifically, the present invention relates to a flow rate control unit disposed in a horizontal connection part, through which solid particles and a combustion flue gas discharged from a fluidized bed furnace generating combustion flue gas are introduced into a cyclone, to control a solid flow between the fluidized bed furnace and the cyclone, the flow rate control unit comprising: a slope member disposed on a lower inner surface of the horizontal connection part to discharge residual solid particles into the fluidized bed furnace or the cyclone; and a control member for changing the flow cross sectional area of the horizontal connection part.
