ABSTRACT:
A proces for separation of dry particulate matter, such as molten slag droplets and/or solid particles, from a hot gas is disclosed in which the gas is first cooled to a temperature in the range from 50.degree. to 500.degree. C. The greater part of the particulate matter is removed from the cooler gas by means of at least one cyclone separator. The gas is then scrubbed with water in a scrubber. Cooling of the hot gas to the lower temperature range is performed by injecting into the hot gas at least part of a purified product gas formed by the process and at least part of an aqueous suspension of particulate matter obtained during scrubbing.
