Title:
CIRCULATING FLUIDIZED BED-TYPE GASIFICATION FURNACE AND FLUID MEDIUM FLOW RATE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2012/176726
Kind Code:
A1
Abstract:
A gasification furnace (110) of a circulating fluidized bed-type gasification furnace (100) turns a flow medium into a fluidized bed and gasifies, with the heat of the fluid medium, an injected gasification raw material, generating a gasified gas. A combustion furnace (102) heats the fluid medium drawn from the gasification furnace. A flow amount adjustment unit (106) distributes the fluid medium heated in the combustion furnace to the gasification furnace and a buffer unit (112). In this way, regardless of the flow amount of the fluid medium in the entirety of the circulating fluidized bed-type gasification furnace (100), by the buffer (112) bypassing the fluid medium to the combustion furnace (102), a desired flow amount of the fluid medium can be maintained in the gasification furnace (110).
