ABSTRACT OF THE DISCLOSURE A coal slagging gasifier is improved by providing an improved slag removal orifice. The orifice is located centrally within the hearth of a gasifier of the type in which hot burner gases are directed up through the orifice to retain the slag in molten condition on the hearth and in which the slag is periodically discharged through the slag removal orifice. The slag removal orifice is formed as a substantially vertical passageway through the removable slag tap member which comprises a solid cast mass of high thermal conductivity metal having an integrally formed metal tube for circulating liquid coolant through the cast mass. The upper tundish surface of the slag tap member slopes downwardly and inwardly and merges with the slag removal orifice. The coolant tube is capable of retaining its shape without any appreciable distortion during the casting of the surrounding metal mass, extends through the cast mass and forms a coolant conduit adjacent to the tundish surface and to the surface of the orifice passageway and spaced from these surfaces a distance of 0.25 to 1.5 inches. The ends of the tube project out from the mass to provide a coolant inlet and outlet. In operation, coolant is circulated through the tube such that the surfaces of the cast mass in direct contact with slag and burner gases are maintained at a temperature of from 50°C. to 400°C.
