ABSTRACT:
A process for cooling and cleaning a hot fly ash containing synthesis gas wherein the gas is first passed through a cooler, the bulk of the fly ash being separated from the cooled gas in a cyclone, whereupon the gas is further cleaned in a water scrubber. At least a part of the fly ash/water slurry obtained in the scrubber is injected into the crude synthesis gas and the fly ash particles are agglomerated in the hot crude gas and/or in the slurry by adding a binder, e.g., water glass.
