Abstract: The invention concerns a stationary power plant, in particular a gas power plant, to generate electricity; having an internal combustion engine, comprising a fuel medium inlet and an exhaust gas outlet, whereas an exhaust-gas flow of the internal combustion engine is discharged via the exhaust gas outlet; having an electrical generator, which is driven by the internal combustion engine to generate electricity, and which is coupled or can be coupled to an electrical grid, in order to feed the generated electricity into said grid; having a fuel medium supply, which is connected to the fuel medium inlet; wherein a steam circuit, in which a working medium is circulated by means of a feed pump, is provided, comprising a heat exchanger arranged in the exhaust gas flow, by means of which waste heat of the exhaust gas flow is transferred to the working medium for partially or completely evaporating the working medium, further comprising a condenser, in which the working medium partially or completely condenses.

Abstract: The invention relates to a drive unit, in particular for a vehicle drive, comprising a drive machine generating driving power, a cooling system for the fluid cooling of the drive machine and/or a component of the drive unit which is supplied at least indirectly with driving power by the drive machine, wherein in the cooling system a coolant circulates; a lubricating circuit for the lubrication of at least one movable component of the drive unit with a lubricant. The invention is characterized in that the drive unit further comprises an accumulation reservoir, in which a comprehensive operating fluid, which comprises a mixture of an ionic fluid and a vaporizable fluid, is stockpiled, wherein the cooling system and the lubricating circuit are at least indirectly fluidically connected to the accumulation reservoir in order to extract lubricant and coolant from the comprehensive operating fluid.

Abstract: A drive train for a motor vehicle is provided. The drive train includes a heat flow generating drive motor, a steam engine in a steam circuit, and an evaporator. The evaporator has an inlet for liquid working fluid and an outlet for evaporated working fluid. The evaporator also includes an auxiliary outlet, via which a portion of the heated working fluid is guided through the inlet into the first evaporator and is discharged with the heat flow, before the residual working fluid in the evaporator is further evaporated by means of the heat flow.

Abstract: A drive train, especially a vehicle drive train, includes: an engine for supplying drive power into the drive train; a cooling circuit in which a cooling medium is revolved in order to cool the engine or an electric generator or another unit; an expansion machine which is driven with fluid or steam as a working medium and by way of which additional drive power can be supplied to the drive train or which drives an electric generator or another unit, the cooling medium of the cooling circuit being simultaneously the working medium of the expansion machine; and a bypass to the expansion machine which is provided through which the working medium of the expansion machine is forced through a switching valve or can be guided past the expansion machine automatically by the prevailing pressure conditions.

Abstract: A heat exchanger plate for an evaporator includes a flow transverse distribution device. Disks of the flow transverse distribution device conduct the medium to be evaporated to the flow channel extending in the direction of the longitudinal axis. The disks include openings allowing a flow of the medium in the direction of the longitudinal axis with comparatively higher flow resistance than in the direction of the transverse axis. The number of disks arranged one behind the other in the direction of the longitudinal axis varies over the width of the heat exchanger plate in the direction of the transverse axis. On each width section, in which the entry of the medium into the disks arranged one behind the other is intended, the comparatively largest number of disks is provided one behind the other. As the distance from the entrance increases, the number decreases in the direction of the transverse axis.
