Title:
PRESSURIZED COAL GASIFICATION FUEL DISTRIBUTION, FEED, AND BURNER SYSTEM
Document Type and Number:
WIPO Patent Application WO2004094568
Kind Code:
A3
Abstract:
A Pulverized Coal Pressurized Gasifier (PCPG) including a gasifier chamber, a fuel (18) chamber and at least one flame retention burner (100). The flame retention burner (100) prolongs high temperature exposure of coal (18) to the hot flame by combining actions of Coanda effect traverse swirl (51) through the flame (54) and induced circulation eddy (53) of combustion gases (52). The Coanda effect is created by swirling air and/or steam flow (48) emerging from air nozzle (14) and following a curved surface (50). The circulation eddies (53) are also induced by curved flow (51).
