Title:
GAS DIFFUSING NOZZLE DEVICE FOR FLUIDIZED BED FURNACE
Document Type and Number:
WIPO Patent Application WO/1988/002839
Kind Code:
A1
Abstract:
A gas diffusing nozzle device for a fluidized bed furnace having high thermal resistance and durability especially, in a high-temperature environment and capable of being manufactured at a low cost, fluidizing a fluid layer uniformly using a fluidized gas jet with a low pressure loss and controlling the flow rate of the fluidized gas jet at the outer circumferential and central portions of the interior of a retort (11) in an arbitrary and individual manner. This device is provided with a circumferential gas supply pipe (19), a central gas supply pipe (24), and a circumferential gas diffusing nozzle section (14) and a central gas diffusing nozzle section (15) respectively connected to these two gas supply pipes. Each of the gas diffusing nozzle sections has a plurality of nozzle pipes (16b, 22) with a plurality of downwardly directed fluid gas ejection ports (17) formed in the lower surfaces thereof, and at least one ring-shaped nozzle pipe (16a, 21) joined to the free ends of these nozzle pipes.
