METHOD AND DEVICE FOR PRODUCTION OF REDUCING GAS FROM PRODUCE GAS

摘要

FIELD: oil-and-gas industry.SUBSTANCE: invention relates to production of reducing gas for recovery of iron ore by cooling and dry dedusting of producer gas (20) produced in gasifier (3) for production of iron and to device to this end. Note here that producer gas (20) after its withdrawal from gasifier (3) and before its dry dedusting is cooled by injection of water via atomisers and by heat exchange. Note here that heat exchange is performed with at least one liquid heat exchange medium.EFFECT: cooling of producer gas without cooling gas circuit, dust cooling and low thermal load at dry dedusting unit.13 cl, 3 dwg
