This patent describes a gasifier for the high temperature gasification of a carbonaceous fuel mixture to produce a hot effluent stream comprised of at least one usable synthetic gas, which gasifier comprises a shell having a reaction chamber in which the fuel mixture is at least partially reacted at an elevated temperature and pressure. A quench chamber in the shell holds a liquid bath for cooling the hot effluent stream, means forming a throat communicating the respective reaction chamber and quench chamber, and an elongated dip tube positioned adjacent to the means forming the throat, having a contact face which defines an effluent guide passage for conducting the hot effluent stream toward the bath. The improvement consists of: a quench ring positioned downstream of the throat and comprising a toroidal shaped body including means forming an annular liquid conducting manifold having an inner wall with an appendage extending outwardly therefrom in a direction toward the effluent guide passage, a liquid distribution ring depending from the toroidal shaped body, being spaced from the appendage to define a constricted, annular liquid circulating channel therebetween, cross passage means communicating the liquid circulating channel with the liquid circulating channel with the liquid conducting manifold, and means forming at least one discharge port in the liquid distribution ring being aligned with the dip tube contact face to direct a stream of liquid coolant thereagainst.
