Title:
AUXILIARY STEAM DEVICE FOR COMPOUND GENERATING INSTALLATION
Document Type and Number:
Japanese Patent JPS61138809
Kind Code:
A
Abstract:
PURPOSE:To feed each plant with auxiliary steam in a well-balanced manner under various operation conditions, by controlling an auxiliary steam feeding flow control valve, which makes pressure inside an auxiliary steam header constant, on the basis of steam pressure at the auxiliary steam feeding side. CONSTITUTION:When steam pressure inside an auxiliary steam header 4 is varied, the auxiliary steam feed setting value obtainable out of outlet main steam pressure in a gas turbine exhaust gas boiler 1 is altered so as to keep steam pressure inside the auxiliary steam header 4 constant whereby actual flow setting is calculated, the actual flow setting after this alteration is compared with an actual auxiliary steam supply, and a pressure regulating valve 8 is opened or closed as far as a portion for the deviation. With this constitution, pressure inside the auxiliary steam header 4 is always kept constant. This control motion takes place at each plant, and the auxiliary steam quantity fed out of each plant is regulated to such one as performing an operating state that brings each plant into the best efficiency, thus a supply of the auxiliary steam quantity is made to be well balanced.
