ABSTRACT

Equipment sizing is determined by conducting mass and energy balances around each unit operation, using actual waste quantities and characteristics. Examples of this sizing process are presented for two markedly different technologies: rotary kiln with afterburner and wet scrubber and circulating bed with dry filters. Dry gas and moisture weights that are produced by combustion of the volatile component, which equals the weight of the volatile component plus the weight of the air provided. Likewise, the air requirement is equal to the sum of the dry gas and moisture of combustion less the volatile component. A heat balance was also performed for the proposed incineration system. This balance assumes that the heat entering a system minus losses equals the heat exiting the system. The result of a heat balance is a determination of the incinerator outlet temperature, outlet gas flow, supplemental fuel requirement, and total air requirement.
