Title:
HYBRID RANKINE CYCLE DEVICE
Document Type and Number:
Japanese Patent JPH0357802
Kind Code:
A
Abstract:
PURPOSE:To prevent the leaking-in of air so as to prevent the lowering of the absorption capacity of an absorption type condensor due to the mixing-in of the air by installing the bearing and the packing of a turbine in the vicinity of the inlet of a low pressure turbine in a hybrid rankine cycle device having the absorption type condenser. CONSTITUTION:The device in the title is constructed by a steam turbine comprising a boiler 1 having a superheater 2 and a reheater 2, a high pressure turbine 5, an intermediate pressure turbine 7 and a low pressure turbine 8, an absorption condenser 18 for absorbing steam discharged from the steam turbine in condensed absorbent solution and a heat exchanger 18, etc. In this case, bearings 11-13 are installed at the steam outlet side of the high pressure turbine 5, between the outlet side of the intermediate pressure turbine 6 and the inlet side of the low pressure turbine 7 and at the inlet side of the low pressure turbine 8. Packings 14, 15, 50, 51 are provided between the bearings 11-13 and each turbine 5-8, which act as a water sealing packing at a place where the internal pressure is lower than the atmospheric pressure and as a labyrinth packing at a place where the pressure is higher.
