Title:
CYCLONE COMBUSTION APPARATUS, COMBUSTION DEVICE, AND COMBUSTION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/161633
Kind Code:
A1
Abstract:
A cyclone combustion apparatus, a combustion device, and a combustion method. The cyclone combustion apparatus comprises a cyclone cylinder (1), a primary air pipe (2), a secondary air pipe (3), and a flue gas discharging pipe (5). The cyclone cylinder (1) is vertically arranged and is provided with a cyclone combustion chamber, a primary air nozzle, a secondary air nozzle, a flue gas outlet, and a slag capturing port (4). The primary air nozzle and the secondary air nozzle are both located on the upper part of the cyclone cylinder (1), and the flue gas outlet is located in the top of the cyclone cylinder (1). The combustion device comprises the cyclone combustion apparatus and a supplementary combustion apparatus located in the downstream of the cyclone combustion apparatus. The supplementary combustion apparatus comprises a supplementary combustion chamber (6). The supplementary combustion chamber (6) is provided with a flue gas inlet a supplementary air nozzle (7). The other end of the flue gas discharging pipe (5) of the cyclone combustion apparatus opposite to the bottom end communicates with the flue gas inlet. The combustion method comprises: introducing primary air containing fuel powder to a cyclone combustion chamber through a primary air nozzle, introducing secondary air to the cyclone combustion chamber through a secondary air nozzle, introducing flue gas generated when the fuel powder is combusted in the cyclone combustion chamber, into a supplementary combustion chamber (6), and introducing supplementary air to the supplementary combustion chamber (6) through a supplementary air nozzle (7), so as to enable combustible matter in the flue gas to be completely combusted.
