-12-METHOD AND APPARATUS FOR OBTAINING MAXIMUMSPRAY FLOW LIMIT OF ATTEMPERATORSABSTRACT OF THE DISCLOSUREAn apparatus and method determines maximum spray flow limitfor an attemperator by using attemperator inlet pressure andtemperature to calculate enthalpy. The enthalpy contributedby water spray flow to the attemperator is also used in thecalculation to determine enthalpy per unit load. Theenthalpy per unit load is multiplied by the actual load ofthe boiler being serviced by the attemperator to produce amaximum spray flow limit for the attemperator.-12-
