摘要： A power plant includes a steam boiler that delivers a rated amount of high-pressure steam at rated temperature and pressure to a steam turbine having a high-pressure stage and at least one low-pressure stage driven by low-grade steam exhausted from the high-pressure stage. A main generator, driven by the steam turbine, furnishes electricity to a variable load. When the load decreases below rated value, the boiler operation is maintained, but low-grade steam exhausted from the high-pressure stage of the turbine is diverted from the low-pressure stage to a heat store large enough to accumulate heat during the time that the power plant operates at less than rated load. A waste heat converter, having its own generator, is responsive to the low-grade heat stored in the heat store, and can be operated selectively to furnish electricity to the load to supplement the output of the power plant. The output of the waste heat converter can be used for peak-power purposes, thereby reducing the size of the main power plant, as well as for furnishing low-level power during shutdown of the main power plant. Moreover, when in operation, the boiler and the high-pressure stage of the turbine operate at peak efficiency, which results in reducing the fuel cost of the power plant.

摘要： Embodiments of the disclosure provide a method for operating a combined cycle power plant (CCPP). The method may include creating a variant control profile for the CCPP for a power plant model of the CCPP. The method may include modifying the variant control profile in response to the variant control profile not reducing the fuel consumption or meeting the quality threshold. The method may also include adjusting the CCPP to use the variant control profile in response to the variant control profile reducing the fuel consumption and meeting the quality threshold. Using the variant control profile adjusts a turbine section inlet temperature schedule or an exhaust temperature schedule for the CCPP.

摘要： A body of water is confined in a closed vessel and heated to above 100.degree.C. This water is then drawn in a liquid state from this vessel and passed through a first expander where it is separated into steam and condensate. The steam from this first expander is used to drive the first stage of a load and the condensate is passed to another expander where it is again transformed into steam and condensate, the steam being used to drive the second stage of the load. Several such expanders are provided and the condensate from the last expander is fed to a low-pressure storage vessel. The high-pressure vessel is filled almost to the top with water during periods of low power consumption and the water is drawn off during peak-power periods. Superheaters may be provided in the outlet conduits of the expanders and the water at above 100.degree.C may be fed directly into the lower-pressure expanders to maintain their operating efficiency.

摘要： A thermal power plant such as a nuclear power plant where a primary circuit is provided for generating primary power while an accumulator circuit communicates with the primary circuit for generating additional power to be utilized for peak loads. The accumulator circuit includes displacement accumulators communicating with steam-generating units for providing the energy to be utilized for the additional peak power. Fluid is circulated between the displacement accumulators and steam generator units by way of a circulating conduit system and a fluid-circulating structure communicating therewith. This fluidcirculating structure is driven from a drive accumulator, so that it is not necessary to use electricity in order to circulate the fluid of the accumulator circuit.

摘要： A steam accumulator has an upright vertically elongated vessel provided internally with a guide that subdivides a body of hot water in the vessel into an outer upflow column and a central downflow column. This guide is at least partially formed as a downwardly tapering frustocone and may have an upper portion carried on a float so as to maintain the upper edge of its upper portion a predetermined distance below the surface of a body of water within the vessel. A discharge conduit opens at the extreme upper end of the vessel and may have a section extending downwardly through the liquid body in the vessel.
