Title:
METHODS OF COOLING PRODUCER GAS FROM HIGH-TEMPERATURE SWIRL FURNACE AND OF ARRESTING ENTRAINED SLAG MIST
Document Type and Number:
WIPO Patent Application WO/2001/045824
Kind Code:
A1
Abstract:
Gas produced in the reaction chamber (1) of a high-temperature swirl furnace is blown through a downcomer (4) into a quenching chamber (2) having a quenching bath, whereby the producer gas is cooled and slag mist entrained in this gas is arrested. Cooling water from a cooling water pouring part at the top of the downcomer is allowed to flow circumferentially of the downcomer along the inner wall surface to form a swirling water membrane. The pouring of the cooling water is effected tangentially as seen in the horizontal section of the downcomer so that the swirling water membrane may be in a direction that is the same as or opposite to that of the swirling flow of the producer gas in the downcomer. The cooling water pouring part can employ an overflow weir system from a trough formed in the outer periphery of the downcomer or a guide plate system having an annular flow channel formed in the inner periphery of the downcomer for direct downflowing.
