Abstract

This patent describes an improvement in a process for the partial oxidation of an ash-containing heavy liquid hydrocarbonaceous fuel, an ash-containing solid carbonaceous fuel, or mixtures thereof to produce an effluent gas stream having a temperature in the range of about 2000{degrees}F to 3000{degrees}F and comprising H{sub 2} + CO and entrained molten slag and ash; and cooling the effluent gas stream by passing the gas stream in succession through a radiant cooling zone, a metal gas transfer line with internal metal heat transfer surfaces, and a convection cooling zone. The improvement involves preventing the molten slag and ash from sticking to the metal heat transfer surfaces on the inside of the gas transfer line comprising: cooling the internal metal heat transfer surfaces of the metal gas transfer line where high gas turbulence occurs to a temperature in the range of about 150{degrees}F to below 700{degrees}F by noncontact heat exchange with a coolant.
