Abstract:
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.

Claim (Index 1):
An axial turbine with interchangeable components, comprising:\n a housing having an interior and a first axis of rotation; a plurality of rotor plates, each having a centerline, a first contact surface and a second contact surface contacting said first contact surface, said first and second contact surfaces being substantially parallel and each of said first and second contact surfaces being flat in the range 0.00005\u2033 to 0.020\u2033, wherein said plurality of rotor plates are positioned proximate one another so that said centerlines thereof are mutually coaxial and are coaxial with said first axis of rotation so as to define rotor portions of a multi-stage rotor assembly, each of said plurality of rotor plates having a radially outermost portion; a plurality of stator plates, each having a centerline, a first contact surface and a second contact surface contacting said first contact surface, said first and second contact surfaces being substantially parallel and each of said first and second surfaces being flat in the range 0.00005\u2033 to 0.020\u2033, wherein said plurality of stator plates are positioned proximate one another so that said centerlines of said stator plates are mutually coaxial and are coaxial with said first axis of rotation so as to define stator portions of a multi-stage stator assembly, each of said plurality of stator plates having a radially innermost portion; wherein said plurality of rotor plates are positioned in alternating relationship with corresponding respective ones of said plurality of stator plates so as to define a multi-stage rotor assembly with an upstream direction, further wherein at least one of said plurality of rotor plates includes a first plurality of vanes with an axial chord and an adjacent one of said plurality of stator plates includes a second plurality of vanes with an axial chord, wherein said first plurality of vanes is axially spaced from said second plurality of vanes to define a space having an axial dimension that is no more than two axial chords to \u00bc of 1% of an axial chord, as measured with respect to the axial chord of the one of said rotor plate and stator plate immediately upstream of said space.
