The City of Indianapolis, Indiana, demonstrated that 34 to 70% of the fuel used for sewage-sludge incineration could be saved. These savings were the result of study of how sewage sludge incineration in a multiple hearth incinerator works, adding instrumentation and controls to the furnace system and training the operators in the technical aspects of sludge incineration. This program saved Indianapolis about $1,000,000 in fuel and maintenance repairs. This fuel-efficient mode of operation also reduced the air pollution from sewage sludge incineration and allowed the city to cancel a $3,000,000 construction program for air-pollution-abatement equipment for sewage-sludge incinerators. Other cities - Nashville, TN; Hartford, CT; and Buffalo, NY - have also adopted the fuel-efficient mode of operation and realize a savings from 40 to 50% less fuel usage for sewage-sludge incineration.
