Abstract
A gasifier for partially combusting a carbonaceous fuel mixture in the combustion chamber of the gasifier. The latter includes a water bath into which the hot effluent or products of combustion are immersed, including a synthetic gas. The products of combustion are directed into the bath by way of a constricted throat section. To avoid excessive erosion action and/or thermal shock to the throat section as a result of exposure to the effluent's high temperatures, the throat section is structured with an internal framework of pipes. The framework is communicated with a pressurized source of a cooling fluid, preferably water, whereby to cool the throat section sufficiently to counteract the ill effects of exposure to contact with the high temperature effluent.
