Document Type and Number:
WIPO Patent Application WO/2019/168211
Kind Code:
A1
Abstract:
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.
