A hybrid heat engine system includes a valve configured to provide first fluid from a heat source. The hybrid heat engine system further includes one or more first pipes fluidly coupled between the valve and a turbine. The one or more first pipes house a second fluid. The hybrid heat engine system further includes a chamber disposed between the valve and the one or more first pipes. The hybrid heat engine system further includes a piston disposed in the chamber between the first fluid and the second fluid. At least a portion of the second fluid is to be pushed through the turbine to generate energy responsive to actuation of the valve.

摘要:
The invention relates to a steam engine plant with a condenser buffer (1) partly filled with liquid, and a radiator (12) provided with a cooling device. The condenser buffer (1) shall have the ability to condense all arriving steam from the steam outlet pipe (5) of the steam engine also at very high, instantaneous power outputs from the steam engine, which may be the case for instance when the plant comprises a stem buffer (18), which is capable of multiplying the maximum steam flow to the condenser buffer (1). The condensing should be performed at a low sound-level, that is without imploding steam bubbles. According to the invention all steam is arranged in the steam buffer to be fed to channels (7) having walls which are provided with a large number of fine openings (8), which all are located below the liquid level in the condenser buffer (1) at different depths and with areas adapted such that the steam exhaust will occur in the shape of concentrated jets (24) of steam in the liquid surrounding the channels. According to a preferred embodiment the bottom parts of the channels (8) are further provided with outlet openings (26) with large area and with valves in the shape of buoyant bodies (27), which restrict or close the outlet openings (26) when the liquid level in the channels (8) approaches the outlet openings.
摘要:
A steam motor with at least one first rotary piston machine (2) driven for depressurizing superheated steam into saturated steam and at least one second rotary piston machine (6) for compressing wet steam into saturated steam, whose pistons are linked in tandem with a common machine shaft (1). A condensor (4) is arranged between the two rotary piston machines for conversion of the saturated steam, by the Carnot cycle process, into wet steam, essentially without any formation of condensate droplets, with an x-value of more than about 0.5, especially about 0.7, whereby this change in state is obtained with a radial or axial acceleration and a reduction in pressure of the steam flow, which is cooled by heat removal during the transition.
