Title:
CONTROL METHOD OF REHEATING TYPE STEAM TURBINE
Document Type and Number:
Japanese Patent JP3144512
Kind Code:
B2
Abstract:
PURPOSE: To operate warming up of a high pressure turbine sufficiently at the time of cold start of a reheating type steam turbine.
CONSTITUTION: Inner pressure of a high pressure turbine is enhanced so as to increase a passing steam amount, and warming up of the high pressure turbine is operated sufficiently, since a reheating type steam turbine is operated by throttling the opening of an intercept valve from an opening characteristic by a set value for the warming up operating period (from B to C) of the high pressure turbine, in the reheating type steam turbine provided with a high pressure turbine, an intermediate pressure turbine supplied with steam discharged from the high pressure turbine after being reheated by a reheater and an opening being regulated by the intercept valve before being supplied thereto, and a low pressure turbine.
