METHOD AND DEVICE FOR ACCELERATED REFORMING OF FUEL WITH OXYGEN

摘要

FIELD: method and devices for production of reformed gases. SUBSTANCE: natural gas and oxygen are burnt in burner at first stage for production of carbon dioxide and water. Combustion products are fed to elongated mixing tube for second stage. Mixing tube is open into reformed gas loop for furnace. Mixture of second flow of gaseous hydrocarbon and oxygen is introduced into second stage through injector for reaction with combustion products from first stage for production of reformed hydrogen carbon dioxide which escape from mixing tube and enter reformed gas loop. Gas and oxygen used for reforming are introduced into second stage and are mixed with combustion products for interaction with carbon dioxide and water at obtaining carbon monoxide and hydrogen. Proposed method and device are suitable as supplement for iron direct reduction unit where iron is reduced to iron in shaft furnace. Proposed method and device may be also used for production of heated enriched natural gas to be used as carbon source in shaft furnace for carburizing of iron. Besides that, said method may be used for control of temperature of reformed gases delivered to shaft furnace. EFFECT: increased productivity of plant. 29 cl, 6 dwg, 1 tbl
