    摘要： A power generation system includes an Organic Rankine Cycle (ORC) electric generator thermally coupled to a stack of industrial heat pumps (IHPs). The ORC requires heat to generate electricity. The IHPs require electricity to generate heat. The IHPs have an efficiency much greater than 100% because some of the output heat from an IHP is pre-existing heat extracted from available source water, The temperature of the source water can be as low as 70° F. By configuring the IHPs to maximize their efficiency, the electricity required to operate the IHPs can be reduced below the output electricity from the ORC. The surplus electricity produced by the ORC is available for export. This coupled ORC/Heat Pump system is an electric generator that requires no fuel to operate and produces no emissions. The required energy is provided by the heat extracted from the source water by the IHPs.

    摘要： An exhaust gas flow regulator and a heat recovery steam generator including the same are provided. The exhaust gas flow regulator includes a plurality of first tubes spaced apart from each other in a vertical direction, a support plate disposed in a direction perpendicular to the extension direction of the first tubes and through which the plurality of first tubes penetrates, and a second tube disposed at one or both ends of the support plate so as to be coupled to the support plate and extending parallel to the first tubes, wherein the second tube is provided with a guide plate disposed to redirect exhaust gases flowing adjacent to the second tube toward the first tube.

    摘要： A process for energy management includes actuating a closed cyclic thermodynamic transformation, first in one direction in a charge configuration/phase and then in the opposite direction in a discharge configuration/phase, between a casing for the storage of a working fluid other than atmospheric air, in gaseous phase and in equilibrium of pressure with the atmosphere, and a tank for the storage of the working fluid in liquid or super-critical phase with a temperature close to its own critical temperature. In the charge phase, the process accumulates heat and pressure. In the discharge phase, the process generates energy. The process includes actuating, with at least one part of the working fluid, at least one closed thermodynamic cycle, even at the same time as the charge phase or as the discharge phase; and heating the working fluid by means of at least one oxy-combustion within the closed thermodynamic cycle.

    摘要： An organic Rankine cycle system with cascade cycles provided with a first organic Rankine cycle which operates at high temperature, in which a first organic working fluid carries out a heat exchange with a hot source fluid and a second organic Rankine cycle which operates at a temperature lower than the temperature of the first organic Rankine cycle and in which a second organic working fluid carries out a heat exchange with the same hot source. The evaporator of the first organic Rankine cycle is fed by the entire flow rate of the hot source fluid, while the evaporator and the preheater of the second organic Rankine cycle are fed by a first partial flow of the hot source fluid, the remaining second partial flow of the hot source fluid being used to partially carry out the preheating of the organic working fluid of the first organic Rankine cycle.
