摘要:
The invention relates to a steam turbine (10), in particular for using the waste heat of an internal combustion engine (2), comprising at least one rotor (26) and at least one stator (20), said stator (20) comprising at least two nozzles (22) which are arranged in parallel in relation to each other. The nozzles (22) are designed for different load points of the rotor (26) and can be switched on and off independently from each other.
摘要:
In a Laval nozzle (10) having a flow channel (12), which has a flow cross-section (14) extending in a convergent-divergent manner, according to the invention the flow channel (12) comprises mutually opposing first flow channel walls (16, 16′), which are formed by two nozzle bodies (18, 18′) spaced a fixed distance apart from one another. Two mutually opposite second flow channel walls (20, 20′), which can be moved relative toward one another or away from one another for adjusting the flow cross-section (14) of the flow channel (12), are disposed between the nozzle bodies (18, 18′).

摘要:
A thermoelectric generator and a method for manufacturing a thermoelectric generator are described. The thermoelectric generator, having a housing in which at least one heat source tube, at least one heat sink tube, and at least one generator element are between the heat source tube and the heat sink tube. A pretension mounting device is in the housing and provides an elastic force via which the tubes are pretensioned relative to one another and which compresses the tubes and the generator element in-between. An inner side of the housing of the pretension mounting device forms a support for the pretension mounting device, which is acted upon by a counterforce to the elastic force of the pretension mounting device.
摘要:
An internal combustion engine having an exhaust gas recirculation device for recirculating exhaust gas of the internal combustion engine to a fresh-air side of the internal combustion engine. For this purpose, it is provided that the exhaust gas recirculation device has at least one compressor for compressing the exhaust gas supplied to the fresh-air side of the internal combustion engine.
摘要:
A device for utilizing the waste heat of an internal combustion includes a single-stage or multi-stage supercharging device, which is designed as an exhaust-gas turbocharger in particular. The single-stage or multi-stage supercharging device is assigned an additional supercharging device including an expansion machine acted upon by an auxiliary circuit, in particular a steam circuit.

摘要:
A thermoelectric module having a plurality of p-n-couples, every two adjacent p-n-legs forming one p-n-couple. The p-n-legs are each manufactured from conductive materials. The p-n-legs of the plurality of p-n-couples are separated in an alternating sequence by an electrically insulating gap which creates a meandering current flow.
摘要:
A method for operating an internal combustion engine (10) having a steam power plant (12), in which the exhaust gas of the internal combustion engine (10) at least indirectly heats the steam and this steam drives a turbine (26), the steam power plant (12) being sometimes, in particular at the beginning of operation, initially operated in a protection operating mode, in which the protection of the turbine (26) from damage by water droplets has priority.
