    摘要： A closed cycle thermodynamic apparatus (10) is provided for powering a combustion machine. The apparatus (10) has a compressor (12) for compressing a working medium from a reservoir (14) at temperature T1. The temperature of the working medium increases during compression and reaches temperature T2 when leaving the compressor (12). It is then expanded in an expander (16) for turning the machine. In this manner mechanical work is extracted from the working medium. The apparatus (10) has a first heat exchanger (18) and a second heat exchanger (20) connected to the compressor (12) andthe expander (16) in a closed cycle. It also has a burner (22) and a third heat exchanger (24). Air, as a Heat transfer medium, at ambient temperature T5 is induced into the second exchanger (20) to cool the working medium by receiving heat therefrom. The temperature of the working medium decreases from T4 to T1 before entering the compressor (12) for repeating the cycle. The air which is now at a higher temperature T6 is conveyed to the burner (22) where it is mixed with fuel to form a combustion gas reaching an even higher temperature at T7 and passed into the first exchanger (18) for heating the working medium at constant pressure. In this manner the temperature of working medium increases to T3 when entering the expander (16) and following expansion for conversion to mechanical power its temperature reduces to T4. The apparatus (10) thereby recovers heat at all the heat exchangers (18), (20) and (24). This reduces the amount of fuel required to heat the air for combustion.

    摘要： A closed loop vapor cycle generated by a device formed by heat transfer and a vapor expander (1) is utilized to convert waste heat from conventional power systems into additional thermodynamic work, thereby improving the overall power system efficiency. Superheated vapor (i.e. steam) is instantaneously produced inside energy transfer means (88) where waste heat is converted into fluid energy with desired thermodynamic properties. The superheated vapor is then converted into mechanical energy through work-producing units (expanders), thereby returning a significant fraction of the energy contained in the waste heat to the power system.

    摘要： The invention concerns a gas turbine system (16) consisting of a compressor (1), a combustion chamber (2), a turbine (3) and at least a cold source (4), said turbine system being driven by a carbon dioxide/water mixture. In the combustion chamber (2), a hydrocarbon reacts as fuel (7) with oxygen (8), and the excess carbon dioxide thus produced and water (14) are tapped in the circuit. The compressor (1) and the turbine (3) respectively comprise a rotor with vanes, and a housing with flow channels and guide grids. The invention is characterized in that the compressor (1) and/or the turbine (3) are adapted to the working fluid expansion properties, different from those of air, by modification of the flow channels, the vanes and/or guide grids.

    摘要： The aim of the invention is to further improve the closed cycle for generating electric power in such a way that efficiency is enhanced and general pressure and temperature requirements regarding the working fluid used are substantially reduced. The invention also seeks to provide an improved technical solution that meets the requirements of continuos operation at rated output despite fluctuations in load requirements. This is achieved through a multistep steam power operating method for generating electric power in a cycle by using an additional gaseous energy carrier to increase the pressure, the temperature and the volume of the working fluid in the cycle and by recirculating the working fluid in the cycle in such a way that continuously overheated steam is used as a working fluid. The invention can be used in the generation of electric power in a cycle.

    摘要： A heat engine utilizing a cycle having an isenthalpic pressure-increasing phase wherein, in the entropy-reduction phase of the cycle for changing the state of the working fluid, in order to have at least a part of that phase change at constant enthalpy, a compensating fluid (high-pressure feed) at a pressure higher than that of the cycle working fluid is introduced into the cycle system at the beginning of the isenthalpic change, thus increasing the pressure of the working fluid, and then the entropy of the working fluid is reduced by discharging a part of the working fluid to the outside of the cycle system at the end of the isenthalpic change.
