Infinity Turbine 1 MW ROT Turbine Dual 24 inch diameter rotors with 12 inch stack height with three stages

Radial Outflow Turbine 1MW AC Generator Hermetically Sealed

Using a scaled up version of existing ROT technology, this design may produce 1 megawatt of power. Turbine would operate at full load speed of 3600 rpm. Turbine is direct mounted to an induction generator (2-pole). Due to the large size of the generator, it is likely a higher voltage than typical (2400V+) and would probably need to be direct grid connect because grid tie controllers cannot be found in this size or voltage. Size of generator likely to be 31in OD and needs a custom cast iron housing for direct refrigerant cooling.

Construction of plates and turbine are possible using current manufacturing capabilities. Large cast iron housings are likely to be outsourced to a vendor (several available). Generator may be an induction motor from a chiller motor supplier (operating in reverse) if no generator suppliers can be found.

1 MW ROT Turbine with Dual Rotors that have Three Stages each

Heat Exchanger Design Requirements

Heat exchanger design should be 212F (evap water in), 95F (condenser water in), 20 F ranges and 20 F approaches. This requires 125 lbm/s refrigerant flow and provides 10 persent system efficiency (Evap heat = 30,000,000 Btu/hr).

Oversize the condenser for better cooling. To save on manufacturing, make both evaporator and condenser same size to take advantage of economies of scale.

Turbine is dual sided ROT with 3 stages (4.5 inch blade heights per side). Overall Diameter is 24in.

Designed to produce 1MW output

Waste Heat Power Technology Using ORC Organic Rankine Cycle: The ORC unit is a system based on a closed-loop thermodynamic cycle for the generation of electric and thermal power, especially suitable for distributed generation. ORC systems can generate electric and thermal power exploiting multiple sources, such as renewables (biomass, geothermal energy, solar energy, GPU waste heat), traditional fuels and waste heat from industrial processes, waste incinerators, engines or gas turbines.
