Title:
FLUIDIZED BED TREATMENT FURNACE
Document Type and Number:
WIPO Patent Application WO/2022/003748
Kind Code:
A1
Abstract:
A fluidized bed treatment furnace (10) is provided with a primary combustion chamber (11), a secondary combustion chamber (13), and a furnace pressure stabilization chamber (12). The primary combustion chamber (11) has a primary combustion region. The primary combustion region is for performing primary combustion of waste in a state in which a gas for fluidization is supplied to a fluidization medium, and the fluidization medium is fluidized. The secondary combustion chamber (13) has a secondary combustion region. The secondary combustion region is for performing secondary combustion to combust primary combustion gas which includes uncombusted gas produced during primary combustion. The furnace pressure stabilization chamber (12) is a space connected to the primary combustion chamber (11), has a larger volume than the required volume for connecting the primary combustion chamber (11) and secondary combustion chamber (13) without primary combustion or secondary combustion occurring, and stabilizes gas pressure in a furnace.
