摘要： A power generating system includes a flow dividing structure, a first detector, a flow dividing adjusting valve, a heat accumulator, a heat exchanger and a turbine. The flow dividing structure divides a first heat medium into a first flow path and a second flow path. The first detector detects a flow rate of the first heat medium. The flow dividing adjusting valve opens the second flow path when the flow rate of the first heat medium exceeds a predetermined value. The heat accumulator accumulates the first heat medium via the second flow path and delivers the first heat medium at a temporally leveled flow rate. The heat exchanger transfers heat from the first heat medium to a second heat medium having a lower boiling point than the first heat medium. The turbine rotationally moves by the second heat medium with heat having been transferred by the heat exchanging unit.

摘要： The solar-based power generator is a system for producing usable electricity from water, which is heated through concentration of ambient, environmental light. The generator includes a reservoir having an open upper end. The reservoir receives a volume of water therein. A convex lens is mounted on an upper edge of the reservoir. The convex lens covers the open upper end. A steam output port is in fluid communication with a steam-based electrical generator. The convex lens concentrates ambient light on the water stored within the reservoir, thus heating the water and to converting the liquid water to steam. Additionally, a methane-burning electrical generator is in communication with the reservoir. Pollutants in the water produce methane during heating and decomposition, which is burned by the methane-burning electrical generator.

摘要： A fluid storage tank can be configured to store a cooling fluid in a liquid state and a gas state. A first heat exchanger can be configured to release heat into the fluid storage tank. A second heat exchanger can be disposed fluidly downstream of the fluid storage tank and configured to exchange heat between the cooling fluid and a heat load. A pressure control device can be disposed fluidly downstream of the second heat exchanger. One of the first cooling fluid that has been heated by the second heat exchanger or a second cooling fluid different than the first cooling fluid can pass through the first heat exchanger and thereby heat upstream first cooling fluid resident in the fluid storage tank.

摘要： A steam power plant is suggested having, parallel to the high-pressure preheater passage (VW4 to VW6), a heat reservoir (A) which is loaded with preheated condensate in weak-load times. This preheated condensate is taken from the heat reservoir (A) for generating peak-load and inserted downstream of the high-pressure preheater passage (VW4 to VW6) into the condensate line (19.2) resp. the feed water container (8). Thus it is possible to quickly control the power generation of the power plant in a wide range without significantly having to change the heating output of the boiler of the steam generator (1). A steam power plant equipped according to the invention can thus be operated with bigger load modifications and also provide more control energy.

摘要： A thermal source provides heat to a heat engine and or one or more thermal demands, including space and water heating and heat storage. Additionally the output of the heat engine may be used for local in situ electricity needs, or directed out over the grid. A system controller monitors conditions of the components of the system, and operates that system in modes that maximize a particular benefit, such as a total accrued desired benefit obtained such as reduced electricity cost, reduced fossil fuel use, maximized return on investment and other factors. The controller may use past history of use of the system to optimize the next mode of operation, or both past and future events such as predicted solar insolation.

摘要： Disclosed illustrative embodiments include systems and methods for power peaking with energy storage. In an illustrative, non-limiting embodiment, a power plant includes a thermodynamic piping circuit having a working fluid contained therein, and the working fluid has a flow direction and a flow rate. Power plant components are interposed in the thermodynamic piping circuit. The power plant components include a compressor system, a recuperator system, a heat source, a turbine system, a heat rejection system, and a thermal energy storage system. A valving system is operable to selectively couple the heat rejection system, the thermal energy storage system, and the compressor system in thermohydraulic communication with the working fluid maintaining the flow direction and the flow rate to implement a thermodynamic cycle chosen from a Brayton cycle, a combination Brayton cycle/refrigeration cycle, and a Rankine cycle.
