摘要: Direct gasification of a high BTU content fuel gas from hydrocarbon solid waste material W which may include some glass is effected by preheating heat carrier solids HCS in flash calciner to temperature capable thermally cracking the directly into gas. The are separated products combustion and fed sealed refractory lined horizontal axis rotary kiln retort concurrently with W. Momentary contact mixing absence oxygen sufficient crack product. Separated returned for reheating. A trommel, coupled output having trommel screen mesh openings smaller than agglomerates, but sized larger HCS, permits separation discharging agglomerates downstream end prevent shut down direct unit. steel industry water treatment plant sludge, automobile shredded refuse ASR, municipal MSW derived RDF oil mill scale effectively achieved, irrespective contaminant.
