Obtaining consistent and predictable heat recovery from industrial incineration depends on design selections
Industrial waste incineration today is cost-effective only in the context of waste-heat recovery and energy production. (One exception is hazardous waste incineration, but that is outside the scope of this paper.) The energy savings gained by substituting plant waste for natural gas and oil, combined with savings in landfill and waste-hauling charges, can, over time, more than offset the costs of construction and capital equipment financing, operation, and maintenance. The economic benefits are contigent on efficient and reliable heat release and heat recovery from waste incineration. Operating problems result in lost energy production, as well as increased labor, material, and auxiliary fuel costs. The problems can be minimized, if not totally prevented, by proper selection of an incineration system design suitable to the particular characteristics of an organization's current and future anticipated waste. These characteristics include waste volumes, chemical composition, combustion properties, and others. The heating values of autogenous combustible industrial wastes start at 4,000 Btu/lb and go up to 18,000 Btu/lb. Moisture can vary from 0% to 75%, with 55% being the typical practical limit for incineration. Inerts and ash can total as much as 35% to 50%. A combination of all or some of these three waste constituents should result in an average heating value of 4,000 Btu/lb to 18,000 Btu/lb to burn successfully without the need for additional fossil fuel energy. The system that can successfully burn products through this entire range with consistent reliable heat recovery and low emissions with low maintenance offers the purchaser the opportunity to successfully amortize his equipment. The more limitations in a system design which cannot perform to the preceding criteria, the greater risk in purchasing the system.
