Title:
COMBUSTION FLUE GAS SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/169126
Kind Code:
A1
Abstract:
A combustion flue gas supply device includes a furnace body. A combustion chamber (5) is arranged in the furnace body. A combustion tray (6) is provided in the combustion chamber (5). A lower air cavity (7) for air intake is arranged at the underside of the combustion tray (6). A perpendicular material feeding device (12) is arranged at the bottom of the furnace body. The inlet of the perpendicular material feeding device (12) is connected with the outlet of a horizontal material feeding device (10). The outlet of the perpendicular material feeding device (12) is communicated with the combustion chamber (5) at the lower air cavity (7) and the combustion tray (6). The side wall of the combustion chamber (5) is composed of an outer wall (21), a middle wall (23) and an inner wall (24). An inner layer air channel between the inner wall (24) and the middle wall (23) is connected with main air intake fans (3, 22). Multiple air intake nozzles (20) with vertically distributed air spraying axes are arranged on the inner wall (24) to communicate with the inner layer air channel and the combustion chamber (5). An outer layer air channel between the outer wall (21) and the middle wall (23) is connected with an air curtain fan (8), and the inlet of the air curtain fan (8) is arranged at the lower portion of the outer layer air channel. The upper end of the outer layer air channel is communicated with the top of the combustion chamber (5), and a de-slagging device is arranged corresponding to the combustion tray (6). The device is used for generating hot flue gas. The furnace body has small volume, flexible arrangement, sufficient combustion, and high thermal efficiency, and automatic fuel supplying and de-slagging can be achieved.
