Development of pilot plant gasification systems for the conversion of crop and wood residues to thermal and electrical energy
To facilitate the successful utilization of this energy at the farm, processing plant or lumber mill a simple, low-cost method of recovering thermal and electrical energy from these residues is required. Downdraft gasification is one such method. The downdraft producer is a moving, packed bed, vertical-flow reactor employing a cocurrent gas flow. A batch-filled, laboratory-scale producer (capacity of 40 to 90 fuel lb-h/sup -1/) has been used to study the gasification characteristics of residues and to test different designs of grate and firebox. A 10 Kw engine-generator set, fueled with producer gas, has been demonstrated, running continuously, for periods up to 4 hours. Two pilot plant proucers systems were designed and constructed to demonstrate gasification in actual application. One unit is supplying 10 million Btu-h/sup -1/ as hot, particulate-free gas, to the burner in a steam boiler, replacing natural gas. A second unit generates a fuel gas from corn cobs which is cleaned, cooled and supplied to a 180 Hp dual-fuel, turbo-charged, intercooled diesel engine that is direct-coupled to a 100 Kw generator.
