Title:
蒸気タービンの低圧タービン部の冷却方法および装置
Document Type and Number:
Japanese Patent JP3866288
Kind Code:
B2
Abstract:
A method and a device for cooling a low-pressure turbine section of a steam turbine connected in a water/steam circuit, include feeding a coolant flow through parts of the low-pressure turbine section, in particular during idling operation. Condensate bled from a condenser connected downstream of the steam turbine is used as a coolant for especially effective cooling while simultaneously utilizing heat obtained in the process. The condensate emits heat absorbed during the cooling to the water/steam circuit. A coolant line which is connected to the outflow side of the condenser is connected to the low-pressure turbine section. A heat exchanger is connected to the coolant line and in the water/steam circuit.
