摘要： The invention relates to a method for increasing the efficiency of a turbomachine, wherein a fluid guided through the turbomachine transfers kinetic energy to the turbomachine. The object of the invention is to increase the efficiency of a turbomachine. This object is achieved in that the fluid or at least one fluid component of the fluid is compressible, and that the flow velocity of the fluid reduced in the turbomachine (1) during the transfer of kinetic energy is increased directly downstream of the turbomachine (1) by a force FB generated by means of a force field and acting in the direction of flow, by converting potential energy of the fluid into kinetic energy of the fluid to such an extent that the pressure of the fluid, which is reduced in the turbomachine (1), is thereby increased again to at least 0.1 times the pressure of the fluid upstream of the turbomachine (1).

摘要： In some embodiments the disclosure is directed to a closed-loop piston engine system using a recirculating carbon dioxide (CO2) system with supercritical carbon dioxide (scCO2) as a working fluid. The closed-loop piston engine system may include a scCO2 injector; a superheating nozzle region; a first valve; a second valve; a piston moving in the cylinder and coupled with a crankshaft, the piston being driven toward a centerline of the crankshaft during a power stroke using a connecting rod and causing the crankshaft to rotate thereby causing one power stroke per piston per crankshaft rotation and thereby producing two power strokes for every single power stroke that a similar engine would produce if run as a hydrocarbon fuel powered internal combustion engine. The recirculating CO2 system recirculates the used carbon dioxide and there are no carbon dioxide emissions from the system.

摘要： A heat recovery system that includes at least one an engine, a radiator, an Organic Rankine Cycle (ORC) and a thermo-electric generator (TEG). The radiator may be coupled to the reciprocating engine, and the ORC may be coupled to the reciprocating engine and to the TEG. A control module in the system is configured to divert reciprocating engine jacket water fluid through any of the radiator, ORC and TEG to increase the energy efficiency of the reciprocating engine through heat recovery caused by the diverted fluid.

摘要： An energy storage device having: a high-temperature regenerator containing a solid, particularly porous storage material (S); a working gas (A) as the heat transfer medium to transfer heat between the storage material (S) and the working gas (A) flowing through; and a charging circuit and a discharging circuit for the working gas (A). The charging circuit is designed such that starting from a pre-heating unit at least one first heat transfer duct of a recuperator, a first compressor (HO), the high-temperature regenerator, a second heat transfer duct of the recuperator and then a first expander are interconnected, thus forming a circuit, so as to conduct fluid. The first compressor is coupled with the first expander, and the first compressor forms part of a first piston machine (K1) and the first expander forms part of a second piston machine (K2), the piston machines (K1, K2) being operable either as a compressor or as an expander such that the first compressor of the charging circuit forms a second expander in the discharging circuit and that the first expander of the charging circuit forms a second compressor in the discharging circuit. The high-temperature regenerator can be connected to either the charging circuit or the discharging circuit to conduct fluid and can be controlled such that the high-temperature regenerator, the compressor and the expander form either part of the charging circuit or part of the discharging circuit. The charging circuit, the discharging circuit and the high-temperature regenerator have the same working gas (A) so that the working gas (A) comes into direct contact with the storage material of the high-temperature regenerator both in the charging circuit and in the discharging circuit.

摘要： A system for generating steam supplies of coal another material to one or more processing chambers. Each processing chamber includes a plasma arc torch that heats the material in the presence of water and a treatment gas at an extremely high temperature. A product gas stream is delivered from each processing chamber to a heat recovery steam generator (HRSG). Each HRSG generates steam that is used to drive a steam turbine. The processing chambers and HRSGs are fluidly connected so that the product gas streams moves from a processing chamber, to a HRSG, to another processing chamber, and then to another HRSG, etc. Within any of the HRSGs, or after the final HRSG, water in the product gas may condense to liquid water that may be redirected to any of the processing chambers. In addition, CO2 from the final HRSG may be redirected into any of the processing chambers to facilitate further reactions in the chambers.

摘要： An external combustion engine including a burner element, a heater head, a piston cylinder containing a piston, a cooler and a crankcase. The crankcase includes a crankshaft, a piston rod connected to the piston, a drive mechanism for converting the linear motion of the piston rod to rotary motion of the crankshaft and a linear cross-head bearing that is connected rigidly to the piston rod at one end and to the drive mechanism at the other end. Also the external combustion engine includes a piston clearance seal and a piston rod seal unit that has floating rod seals. The piston includes a inner dome to reduce axial heat transfer via radiation and convection.
