Abstract
A gasification reactor has a mixing tube above it in a common pressure vessel and the mixing tube is provided with a gas cooling heat exchanger. A driving gas feeder draws a portion of the mixture of quenching gas and raw gas from the mixing tube, passes it through the gas cooling heat exchanger and feeds it as a quenching gas to the raw gas at the inlet side of the mixing tube. At least one further heat exchanger in the same pressure vessel or in another pressure vessel, receives the mixture of raw and quenching gas beyond the mixing tube.
