摘要： Systems and generating power in an organic Rankine cycle (ORC) operation to supply electrical power. In embodiments, an inlet temperature of a flow of gas from a source to an ORC unit may be determined. The source may connect to a main pipeline. The main pipeline may connect to a supply pipeline. The supply pipeline may connect to the ORC unit thereby to allow gas to flow from the source to the ORC unit. Heat from the flow of gas may cause the ORC unit to generate electrical power. The outlet temperature of the flow of the gas from the ORC unit to a return pipe may be determined. A bypass valve, positioned on a bypass pipeline connecting the supply pipeline to the return pipeline, may be adjusted to a position sufficient to maintain temperature of the flow of gas above a threshold based on the inlet and outlet temperature.

摘要： A constant density heat exchanger is provided. The constant density heat exchanger includes a housing extending between a first end and a second end and defining a chamber having an inlet and an outlet. A first flow control device is positioned at the inlet of the chamber and movable between an open position in which a working fluid is permitted into the chamber and a closed position in which the working fluid is prevented from entering the chamber. A second flow control device is positioned at the outlet of the chamber and movable between an open position in which the working fluid is permitted to exit the chamber and a closed position in which the working fluid is prevented from exiting the chamber. A heat exchange fluid imparts thermal energy to the volume of working fluid held at constant density within the chamber by the first and second control devices.

摘要： The present invention refers to the technical field of thermodynamic engines, and more specifically to a heat engine that operates with gas in closed loop in differential configuration which is characterized by performing a thermodynamic cycle eight transformations or otherwise explain, it performs two thermodynamic cycles simultaneously, each with four interdependent, additional transformations, two of these transformations “isothermal” and two “adiabatic” in mass transfer in phases of adiabatic processing to provide a new performance curve no longer dependent solely on temperature but the mass transfer rate which allows the construction of machines with high yields and low thermal differentials.

摘要： A compressed-air energy storage system according to embodiments of the present invention comprises a reversible mechanism to compress and expand air, one or more compressed air storage tanks, a control system, one or more heat exchangers, and, in certain embodiments of the invention, a motor-generator. The reversible air compressor-expander uses mechanical power to compress air (when it is acting as a compressor) and converts the energy stored in compressed air to mechanical power (when it is acting as an expander). In certain embodiments, the compressor-expander comprises one or more stages, each stage consisting of pressure vessel (the “pressure cell”) partially filled with water or other liquid. In some embodiments, the pressure vessel communicates with one or more cylinder devices to exchange air and liquid with the cylinder chamber(s) thereof. Suitable valving allows air to enter and leave the pressure cell and cylinder device, if present, under electronic control.

摘要： The invention is a rotary engine comprised of at least one and usually a plurality of independent partial engines. Two different processes can be carried out in each independent partial engine both of which are used to operate the engines. The processes of the invention are basically two different and separate closed cycle processes that can both operate within the same geometric confinement, i.e. the same expansion chamber or expansion chambers, at the same time. The primary process performs the main function of converting heat to kinetic energy and is necessary in all engines of the invention. It is a unique process that uses the expansion of gases and also the contraction of the condensing gases after their expansion. The secondary process is needed for start-up and to provide additional power in case the engine might go into a stall. In most engines of the invention both processes are needed to operate the engine.

摘要： A domestic combined heat and power system comprising a Stirling engine (1) and water heater in the form of a supplementary burner (17). The exhaust gas from the Stirling engine is used to preheat combustible gas entering the Stirling engine and subsequently used to heat the water. The water heater (15) has a helical water duct (41) towards the periphery of a housing (39). Separate parts of this duct are heated, in series, by the exhaust gas from the Stirling engine and the supplementary burner (17) firing radially outwardly through the helical duct.

摘要： The power output of a free piston Stirling engine is regulated by a valve in the gas flow path from the cold space through the regenerator to the hot space. The valve causes restriction of the gas flow path as in response to piston excursion beyond a selected excursion amplitude. Increased excursion causes increased restriction. The result is that, for piston excursions beyond the selected amplitude, the power out diminishes for increased stroke making the engine stable with any load from zero to maximum and avoiding runaway.
