The trommel through-put, the majority of which is combustible, is transferred to another inclined steel pan, cleated conveyor, which deposits the fuel product on the incinerator feed storage floor. At this point, a front-end loader either stockpiles the fuel prod- uct or feeds the incinerator charge boxes. The incinerator feed storage area has a minimum capacity of 4 days of processed refuse. The steam or electric power generating section is designed to operate 24 hours per day, 7 days per week. From their charging boxes, the fuel product is fed into a primary chamber where it is burned under controlled air conditions. The resulting; gases are passed through a second chamber, where excess air is injected to complete combustion. Auxiliary fuel is required in minimal quantities to maintain proper combustion temperatures. Combustible particulate matter burns off, and the hot cases are passed through a waste heat boiler to produce steam, which may be sold directly or, if electricity is to be produced, piped to a turbogenerator, then through a condenser in which heat transfer is accomplished by cooling tower water. The condensate is then piped back to the boiler. Makeup water is required for the boiler because of blowdown and evaporation losses and is also required for the cooling tower because of evaporation losses. Cooling tower makeup water is subjected to chlorination. The flue gas train in- cludes fans and a baghouse. Residue remainingafter combustion soon is dropped into an ash pit where it is water-quenched and mechanically conveyed to a storage bin to await truck transport to a landfill. Electricity, if generated, will be produced at a maximum of 13 , 800 volts, 3 phase, 60 Hz. Generated electricity is used for both in- plant processing and export as an energy product. Power will be provided at 13 , 800 volts to the electrical distribution network for transformation (if required) and transmission. The package incinerator units utilize No. 2 fuel oil for start-up, temperature maintenance and as a back-up fuel should the supply of refuse be cut off. Sufficient on-site storage has been provided for a minimum of 5 days of operating only on fuel oil. The capa- bility to transfer wastes directly to long-haul vehicles for deliv- ery to the landfill will be maintained as a back-up in the event of a total process shutdown. Basic Design Parameters Parameters used to design the package incinerator/power plants are listed below in Table 5-1. 20,
