METHOD AND APPARATUS FOR OBTAINING MAXIMUM SPRAY FLOW LIMIT OF ATTEMPERATORS |
摘要 |
A maximum spray flow limit for an attemperator is determined by using attemperator steam inlet pressure measured by a pressure sensor (10) and temperature measured by a temperature sensor (12) to calculate enthalpy. The enthalpy contributed by water spray flow to the attemperator is derived from a spray temperature sensor (40) and may be used in the calculation to determine enthalpy per unit load. The enthalpy per unit load is multiplied in a multiplication block (36) by the actual load of the boiler being serviced by the attemperator to produce a maximum spray flow limit on a line (44) for the attemperator. |
