Abstract: Slagging gasifier (10) for the gasification of coal and organic waste materials. The gasifier includes a vertical blast furnace (12) having a hearth section (18) at the bottom thereof. A slag tap hole (30) is formed in the hearth section and opens into a quenching vessel (36). A honeycomb structure (56) is formed on the inner surface of said hearth section (18) in the area surrounding said slage tap hole (30), ant the inner wall of the hearth section. A plurality of tuyeres (42) extend into the hearth section (18) and feed the furnace with steam and oxygen so as to permit the oxidation of coal and organic waste materials fed into the furnace. As a result of the oxidation, gas and molten slag are formed in the furnace. The slag is collected in the hearth section (18) and exits the hearth section via the tap hole (35). One or more conduits (58, 62) are provided for recycling (either internally or externally) the gas exiting the top of the gasifier with the tars, oils, and particulates entrained therein to the partial combustion zone of the gasifier where the oils and particulates are converted to non-condensible gases. A portion of the tar-free product gas is removed from an intermediate point in the gasifier below the Pyrolysis and Coking zone.
