Title:
FLUIDIZED BED FURNACE AND WASTE PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2011/161948
Kind Code:
A1
Abstract:
The disclosed fluidized bed furnace is characterized by: forming a first fluid region (15), which is fluidized to a degree that waste (18) at the top of fluid particles (12) can be retained, by means of blowing fluidization gas in from the periphery of a mixture discharge port (29); forming a second fluid region (16) that has a higher degree of fluidization of fluid particles (12) than the first fluid region (15) does by means of blowing fluidization gas in between the first fluid region (15) and a reverse-side wall (25) at a high flow rate, and as a result the fluid particles (12) mix with the waste (18) and cause said waste (18) to be gasified; and supplying the waste (18) from a supply-side wall (24) to the fluidized bed (14) in a manner such that the waste (18) is retained over the first fluid region (15) and the retained waste (18) progressively advances into the second fluid region (16).
