  • Waste Heat Recovery from Packaged Incinerators*

    Type 1 waste is assumed with a heat recovery percentage of 55 (low value) being used to calculate net fuel worth. Net worth of fuel is determined by deducting the auxiliary fuel required for the incineration process and figuring the equivalent fuel oil represented by the recovered heat at an 80% boiler efficiency.
