ABSTRACT:
A reactor for gasifying a carbonaceous fuel to produce usable gas, and comprising an insulated outer shell. A reaction chamber within the shell which receives a fuel mixture from an injection burner. The products or effluent of gasification include hot produced gases which are passed through a constricted throat to be cooled in a liquid bath. A dip tube which guides the hot effluent into the bath is provided with a stream of coolant from a quench ring. The latter is supported below the reaction chamber and includes a toroidal body which communicates with a pressurized water source. A narrow channel formed in said body carries a rapidly moving flow of the water to uniformly cool the effluent guide panel whereby to stabilize the latter and reduce the development of thermal strains due to contact with the hot gases.
