Abstract
PURPOSE: To facilitate operation by coupling medium and high pressure turbines and a low pressure turbine constituting a common shaft with a cross-over duct and providing a check valve on the cross-over duct.
CONSTITUTION: Steam flowing from a main steam duct 5 is led through a steam check valve 6 and a steam control valve 7 to drive a high pressure turbine 1 in a P turbine I. Meanwhile, steam flowing through a speed matching valve 22 on a duct 21 drives medium and low pressure turbines 8 and 9 in an S turbine II independently of each other and controls their rpm. Although no steam flows through the low pressure turbine 2 of the P turbine I, the low pressure turbine 2 has no adverse effect for its interior is in the vacuum state and the operating region free from steam flow is below one half the rated rpm. Steam flowing a main steam valve 6 flows into the high pressure turbine, and exhaust gas therefrom is stored in a re-heater 1. A ventilator valve 9 is on-off operated to increase the rpm of the P turbine I up to one half the rated rpm.
