Abstract
A steam turbine plant of one embodiment includes at least one heater configured to change water into steam to produce high pressure steam and low pressure steam having a lower pressure than the high pressure steam, a high pressure turbine including a turbine or turbines connected to each other in series, and having a first inlet to supply the high pressure steam, a second inlet to supply the low pressure steam and located at a downstream of the first inlet, and an exhaust port located at a downstream of the second inlet, the high pressure turbine being configured to be driven by the steam supplied from the first and second inlets, a reheater configured to heat the steam exhausted from the exhaust port, and a reheat turbine configured to be driven by the steam from the reheater.
Claims7
A steam turbine plant comprising:
- a heater configured to change water into steam, the heater producing high pressure steam and low pressure steam having a lower pressure than the high pressure steam by using heat from a single heat source;
- a high pressure turbine having a first inlet to supply the high pressure steam, a second inlet to supply the low pressure steam and located downstream of the first inlet, and an exhaust port located downstream of the second inlet, the high pressure turbine being configured such that the high pressure steam supplied from the first inlet drives the high pressure turbine, expands in the high pressure turbine, decreases in pressure, and is then merged with the low pressure steam supplied from the second inlet in the high pressure turbine, and the merged high pressure steam and low pressure steam further drive the high pressure turbine, expand in the high pressure turbine, decrease in pressure, and are then exhausted from the exhaust port;
- a reheater located downstream of the high pressure turbine and configured to heat the steam exhausted from the exhaust port;
- and
- a reheat turbine located downstream of the reheater and configured to be driven by the steam from the reheater.
