METHOD AND DEVICE FOR COOLING LOW-PRESSURE FRACTIONAL TURBINE |
摘要 |
cooling low-pressure turbines. SUBSTANCE: heat-transfer agent (K') flows through parts 24 of fractional turbine 2 at idling. Low-pressure fractional turbine is included in steam-and-water loop 12 of steam turbine. Used as heat-transfer agent (K') is condensate taken from condenser 4 connected after steam turbine 1; at least one partial flow of heat-transfer agent (K') after flowing through low-pressure fractional turbine 2 is first cooled by transfer of heat to steam-and-water loop 12 and then heat is again supplied to it. Low-pressure fractional turbine is connected to cooling loop pipe line connected in its turn with drain end of condenser 4; heat exchanger of steam-and-water loop 12 is located inside cooling loop pipe line. EFFECT: enhanced efficiency of cooling at idling and/or low load. 10 cl, 2 dwg
