Decribed is a method of cooling partial oxidation gas exiting at a temperature between 1,000 DEG and 1,700 DEG C. from a conically converging outlet portion of a reactor vessel into a subsequent tubular cooling zone. To prevent deposition of sticky molten impurities entrained in the gas stream on the walls in the transition region between the reactor vessel and the cooling zone, the outlet portion of the reactor vessel is provided with a ring-shaped slot for injecting at an angle between 0 DEG to 90 DEG a frustoconical stream of cooling fluid. Another ring-shaped slot is provided in the cooling zone to inject at an angle between 70 DEG to 90 DEG another frustoconical stream of cooling fluid into the cooling zone.
