A turbine and a turbine-generator device for use in electricity generation. The turbine has a universal design and so may be relatively easily modified for use in connection with generators having a rated power output in the range of 50 KW to 5 MW. Such modifications are achieved, in part, through use of a modular turbine cartridge built up of discrete rotor and stator plates sized for the desired application with turbine brush seals chosen to accommodate radial rotor movements from the supported generator. The cartridge may be installed and removed from the turbine relatively easily for maintenance or rebuilding. The rotor housing is designed to be relatively easily machined to dimensions that meet desired operating parameters.

A system and method for decontaminating a fluid and recovered vapor, particularly processing and recycling water used in an oil zone steam process, utilizing a vaporizer-desalination unit to separate a contaminated water flow into a contaminated disposal flow and a clean water vapor flow. The contaminated water flow is recovered after separation from a combined oil and water flow from an oil well. The clean water vapor flow is preferably passed through a steam generator to produce the steam used in the oil zone steam process. The steam is injected into the oil zone of a designated well and then extracted as the combined oil and water flow. Once primed with sufficient external water, the system and method is designed to operate continuously with minimal replenishment because of the water/vapor/steam cycle.

A transducing method comprising: using a working medium of a heat pump (I) to absorb heat from and condense an output pressure working medium gas of a pneumatic motor (J) into a pressure working medium liquid, which is delivered as an input pressure working medium of the pneumatic motor (J); compressing, by the heat pump (I), the working medium after heat absorption to raise the temperature thereof so as to deliver the heat to the input pressure working medium, to enable the same to be heated and vaporized into a pressure working medium gas for actuating the pneumatic motor (J) and then being outputted by the pneumatic motor (J) as the output pressure working medium gas; and delivering the working medium of the heat pump (1) of which the temperature is decreased after the heat thereof has been delivered, to reabsorb heat from the output pressure working medium gas.

A system and process for decontaminating a bio-contaminated wastewater fluid as from a slaughterhouse or similar facility. The system and process recovers purified vapor/steam through a decontamination unit having a plurality of alternating rotating trays and fixed baffles in a processing vessel producing separate purified and contaminant streams. One or more filter/strainer units are disposed in parallel before the decontamination unit, and may be used alternately while the other is cleaned. A rotating shaft connected to the rotating trays may also connected to an electrical generator to provide electricity for circuits and controls in the system.

A power plant and a method for operating such a power plant having at least one generator, which is cooled by a cooling gas cooled by a generator heat exchanger, and a closed cooling water system, to which the generator heat exchanger and additional heat exchangers of the power plant are connected, wherein the generator heat exchanger is a component of an additional cooling water circuit, which serves solely to cool the generator, which is connected to the cooling water system and can be selectively disconnected therefrom by at least one shut-off valve, and which has a pump and at least one refrigerating machine for cooling the cooling water flowing through the additional cooling water circuit.

An electric vehicle including the Rankine cycle in which a circulation system of working fluid is formed is proposed. The Rankine cycle includes a pump configured to circulate the working fluid along the circulation system, a heat source comprising a battery unit, a motor unit, and a solar panel unit to transmit thermal energy to the working fluid circulated by the pump, a power generating unit provided on a path of the circulation system to generate electric energy through the thermal energy of the working fluid passing through the heat source, and a radiator configured to perform a heat exchange process between the working fluid passing through the power generating unit and outside air. The Rankine cycle further includes a flow distributor to distribute the working fluid circulated by the pump to at least any one of the battery unit, the motor unit, and the solar panel unit.
