Title:
SPRAY CONTROL METHOD FOR STEAM TURBINE EXHAUST CHAMBER
Document Type and Number:
Japanese Patent JPS5813109
Kind Code:
A
Abstract:
PURPOSE:To effectively control temperature in the exhaust chamber in such a way that sprayed water particles are atomized by providing a pressure regulating valve by which sprayed water pressure in a spray nozzle is made appropriate through the temperature in an exhaust chamber. CONSTITUTION:A spray nozzle 6 is installed near the upper part of the final stage blades 3 in an exhaust chamber 1. Sprayed water 7 directly cools exhaust air flow and an exhaust chamber casing 5. Temperatures in the exhaust chamber are detected by command of a controller 11, with this taken as the working condition, sprayed water pressure is worked within the proper using of the spray nozzle 6 by means of a sprayed pressure regulating valve 10. Thus, at the same time as sprayed water particles can be prevented from coarsening, temperature in the exhaust chamber can be smoothly controlled.
