ORC Turbine and Generator, And Method Of Making A Turbine

摘要

A turbine-generator device for use in electricity generation using heat from industrial processes, renewable energy sources and other sources. The generator may be cooled by introducing into the gap between the rotor and stator liquid that is vaporized or atomized prior to introduction, which liquid is condensed from gases exhausted from the turbine. 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.

主权项

1. A system for converting heat energy into electricity, comprising:
a turbine having an inlet, an outlet, a stator and a turbine rotor, wherein said turbine is configured to receive a first volume of working fluid via said inlet and to exhaust said first volume of working fluid via said outlet, wherein said turbine rotor rotates about a rotational axis; and a generator coupled with said turbine, said generator having a stator and a generator rotor, said generator rotor being coupled with said turbine rotor so as to be rotatably driven by said turbine rotor about said rotational axis, said generator including a gap between said generator rotor and said stator for receiving a second volume of said working fluid, said gap having an entrance port and an exit port, wherein said generator is designed so that, in operation, said second volume of working fluid present in said gap cools said generator rotor and said stator.
