Description:
A field demonstration project was conducted at Hartford, Connecticut, which showed that the supplemental fuel usage for sewage sludge incineration could be reduced 83%. This was accomplished by using a belt press filter for dewatering which reduced fuel usage 65% and then fuel efficient burning procedures and operator training further reduced that amount 51%. The Hartford plant originally used 122 gallons of fuel per ton of dry sludge burned, now it uses about 22 gallons of fuel per dry ton burned. Essentially all the 22 gallons of fuel are used to keep the incinerators warm on the weekend when sludge is not burned.
