Process for production of gaseous mixture of carbon monoxide and hydrogen and melter-gasifier system for carrying out the process.

摘要

An improved method of removing molten slag from the surface of a molten iron bath (12) in a pressurized melter-gasifier (10) for producing a gaseous mixture of carbon monoxide and hydrogen from coal. The molten slag (14) is continuously removed from the meltergasifier (10) and quenched in a water bath (28). The resulting granular slag is separated from the quenching water (28) and the slag (14) and quenching water are separately removed from the pressurized system. Water economy is achieved by cooling the separated quenching water at atmospheric pressure and then pumping it back into the pressurized system.
