ABSTRACT:
In a power generating installation including a steam turbine-generator system, a source of steam under pressure, and a steam conditioning unit, the steam turbine-generator system including a high pressure turbine and at least one low pressure turbine, each turbine having a steam inlet and an exhaust outlet, and an output shaft coupled to all turbines, and the steam conditioning unit being connected between the exhaust outlet of the high pressure turbine and the steam inlet of each low pressure turbine and being effective to remove moisture from, and reheat, steam flowing between the exhaust outlet of the high pressure turbine and the steam inlet of the low pressure turbine, the steam conditioning unit is composed of two structurally separate devices which include a reheating device which functions exclusively to add heat to the steam and a moisture separating device which acts to remove moisture from the steam.
