Field Test Using Coal: dRDF Blends in Spreader Stoker

pelletized 1/2-inch-diameter by 3/4-inch-long dRDF was co-fired with coal in spreader stoker boilers rated at 7.6 and 9.9 kg/sec (60,000 and 75,000 Ib/hr) of 1034 kPa (150 psig) saturated steam. The field tests were designed to investigate (1) the material handling characteristics of dRDF, i.e., storage in warehouses, drop boxes, and open

A FIELD TEST USING COAL:DRDF BLENDS IN SPREADER STOKER

Dec 22, 2005 · The results indicate that coal:dRDF blends up to 1:2 can be handled and burned in conventional spreader stoker-fired boilers without major equipment modification. As more dRDF was substituted for coal, the flame volume increased, the opacity decreased, the fly ash carbon burnout improved, and the turndown ratio of boiler operation increased.
