A gasifier (10) for partially combusting a carbonaceous fuel mixture in the combustion chamber (13) of the gasifier (10). The latter includes a water bath (26) into which the hot effluent or the products of combustion are immersed, including a synthetic gas. The products of combustion are directed into the bath (26) by way of a constricted throat section (31). To avoid excessive erosion action and/or thermal shock to the throat section (31) as a result of exposure to the effluent's high temperatures, the throat section (31) is structured with an internal framework of pipes (32). The framework (32) is communicated with a pressurized source of a cooling fluid (42), preferably water, whereby to cool the throat section (31) sufficiently to counteract the ill effects of exposure to contact with the high temperature effluent.
