    摘要： The power production process with a gas turbine, where solid fossil fuels, alternative fuels and wastes can be utilized for combustion with air or oxygen as the primary power source. The working medium is the steam-gas mixture of gas supplied by compressor (22) and the cooling medium vapors from the cooled combustion chamber (1), whereas the injected medium is injected into the gas supplied by means of compressor (22) before the compressor (22) or before the heater (7) of the steam-gas mixture or at least between some parts of the heater (7). The gas turbine (28) can be utilized in connection with a regeneration exchanger or with Rankine-Clausius steam cycle equipment utilizing waste heat of the flue gas from the gas turbine (28). The gas turbine (28) operates with the so-called wet steam cycle, which enables utilization of cooling medium heat from the combustion chamber (1), as well as isothermal compression during compression of gas creating the working medium of the gas turbine (28). Together with this gas, the cooling medium vapor from the combustion chamber (1) is used as the working medium. The temperature of the steam-gas mixture in front and behind the gas turbine (28) can be increased by reheating; the temperature of the steam-gas mixture behind the gas turbine (28) can be increased by reheating by the flue gas of the combusted primary fuel.

    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 heat exchanger (50), has a heat exchanger core (51) having an inlet (50I), an outlet (500), at least one first conduit (52) connecting the inlet (50l) to the outlet (50O), at least one second conduit (53) in heat exchange relationship with the at least one first conduit (52), a bypass conduit (56) connecting the inlet (50I) to the outlet (50O) while bypassing the at least one first conduit (52), and a valve (60) in communication with the bypass conduit (56). The valve (60) has a valve member movable between a closed position in which fluid communication through the valve (60) and via the bypass conduit (56) is blocked and an open position in which fluid communication through the bypass conduit (56) and through the valve (60) is permitted, the valve member defining an auxiliary passage, and a thermal fuse overlapping the auxiliary passage and blocking fluid communication through the valve member via the auxiliary passage.
