Book Description
This report presents the results of a field evaluation of the operating prototype modular (package) augered-bed, heat-recovery, solid-waste incinerator (ABI) conducted on 23-28 May 1977. The ABI tested is a horizontal, cylindrical, cast refractory-faced combustion chamber fitted with a water-cooled auger to convey burning waste. Feeding and ash removal are continuous, and steam is produced in a coiled heat exchanger at the base of the stack from water preheated in the auger. The throughput capacity of the furnace is approximately 3.5 tons/hour (3.2 mt/hour), more than three times the capacity of currently marketed modular incinerators. The report furnishes a detailed description of the system evaluated, a critical appraisal of essential unit operations, and environmental and energy data. The satisfactory performance of the furnace, which is a major innovative aspect of the unit evaluated, indicated that it has potential for Army use. However, because of the unreliability of mechanical auxiliaries, inadequate materials of construction, and poor system configuration, the ABI as it presently exists cannot be recommended for immediate deployment for processing solid waste generated on Army fixed facilities and installations. It was concluded that re-engineering around the furnace using established methods could make a practicable heat-recovery solid-waste incineration system available. (Author).
