    Abstract: 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.

    Abstract: A selective deslagging operation is conducted in a partial oxidation reactor wherein a first predetermined portion of the reactor is selectively deslagged by derivatization while limiting derivatizing slag conditions in a second predetermined portion of the reactor. Selective deslagging can be accomplished by controlled oxidation conditions in the reactor that vary from one predetermined portion of the reactor to another. Thus, the slag present in one predetermined portion is derivatized and fluidized for removal from the reactor at a faster rate than the slag present in another portion of the reactor, which is not derivatized or is subjected to more limited derivatizing slag conditions. Derivatized slag can be differentiated from non-derivatized slag that does not flow or more limited derivatized slag that has a lower mass flow rate then the derivatized slag at conditions of controlled oxidation. The derivatized slag can then be selectively removed because it has attained a lower fluidizing temperature.
