Description:
A plant-scale demonstration was conducted on 8 sewage sludge incinerators at Indianapolis, Indiana to reduce fuel consumption. More efficient operating mode of operation was developed, instrumentation and controls were added and an operator training program was conducted to reduce fuel consumption. Over an 8-month demonstration period the fuel usage was reduced 34% for a savings of over $900,000 per year ($1.00 gal fuel). A short demonstration, when technical personnel were present at all times, indicated that the fuel savings could be 75%. It was estimated that all plants in the U.S. could reduce 20-50% of their fuel usage if a similar program were used for sludge incineration. Additional savings of $3,000,000 were realized for air pollution abatement equipment. Particulate emissions were sufficiently reduced so that this additional equipment was not required.
