Abstract

PURPOSE: To lighten the heat load of a reheating turbine, by controlling the temperature of an outlet of a reheater by means of a spray adjusting valve of a by-path of a high pressure turbine.
CONSTITUTION: Steam passing through a high pressure turbine 4 is heated by means of a reheater 10, and supplied to a low pressure turbine 13. Temperature at the output side of the reheater 10 is detected by means of a detector 11, compared 25 with a command 24 and proportionally integrated. Since the signals control a spray adjusting valve 8 for injecting spray water to a temperatre reducing instrument 7 of a high pressure turbine by-path system within the ranges of high and low limiting value 27, 28, the temperature of steam reheated can be made desirable for low pressure turbine metal match without being subject to the influence of the change of the quantity of heat absorbed at the reheater 10.
