MAIN STEAM TEMPERATURE CONTROLLER FOR WASTE HEAT RECOVERY STEAM PRODUCER

摘要

PURPOSE: To provide a main steam temperature controller for a waste heat recovery steam producer capable of ensuring a steam of proper temperature at all times, the steam being fed from the waste heat recovery steam producer in a combined cycle to a steam turbine. ;CONSTITUTION: There are provided a superheater outlet steam temperature detector 13 for detecting steam temperature at an outlet of a superheater, a temperature reducing supplied water flow rate detector 14 for detecting a supplied water flow rate supplied to a temperature reducer 11 disposed between adjacent divided superheaters 5, and a controller 15. A signal from the detector is inputted into the controller 15 which in turn controls the flow rate of the temperature reducing supplied water such that the steam temperature at the outlet of the superheater gets a set value.;COPYRIGHT: (C)1994,JPO&Japio
