    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.

    Abstract: An evaporator, which includes a water chamber for receiving water to be evaporated. A plurality of evaporator tubes which when heated, and when water is on an inner wall of a tube, evaporates at least a portion of that water. A plurality of distributors spatially connecting the water chamber with the evaporator tubes in a manner so that each distributor uniformly and distributes the water from the water chamber to an inner wall of a corresponding evaporator tube. A heat source, which heats the plurality of tubes to an evaporation temperature. Apparatus distills the water vapor resulting from the water evaporation to provide distilled water.

    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.
