摘要： A system for using excess energy of a power generation system and an sCO2 (supercritical carbon dioxide) stream to store and generate power. An air separation unit uses the excess energy to cool and liquify ambient air into liquid nitrogen (L-N2) and liquid oxygen (L-O2). The L-O2 and L-N2 are stored until energy is desired. An L-O2 energy discharge path has an oxygen heat exchanger that vaporizes and heats the oxygen, a combustor that combusts the oxygen and fuel to produce exhaust, and a first turbine is driven by the exhaust to produce energy. An L-N2 energy discharge path has a nitrogen heat exchanger that vaporizes and heats the L-N2, thereby providing expanded nitrogen, and a second turbine is driven by the expanded nitrogen to produce energy. Heat for the heat exchangers on both discharge paths is provided by the sCO2 stream.

摘要： A Stirling cycle type engine is disclosed in which a displacer piston and power piston operate within a cylinder due to flow of a working fluid which is heated and cooled by a heater element and a cooler element. The cylinder is divided into an upper expansion chamber and a lower compression chamber by a displacer piston. The lower chamber is defined between the displacer piston and power piston. The upper chamber and lower chamber are connected to one another through a serially interconnected heater, a regenerator and a cooler, whereby the working fluid flows into the lower chamber from the upper chamber or vice versa. The regenerator and the cooler are disposed on one outer peripheral side of the cylinder and vertically aligned therewith. Thus, the radial size of the engine is reduced without reducing its efficiency.

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.
