ABSTRACT:
A turbine and method of using the same to generate rotational power from a desired geothermal source from which a multi-phase pressurized and heated fluid is discharged, which fluid contains steam and particles of water, and may contain particles of solid material. The turbine includes a rotor plate with a number of spaced discs secured to opposite sides thereof that are rotatably supported in a housing, and the housing having two laterally spaced sets of circumferentially disposed nozzle bodies situated therein that are each adjustable to define a convergent section, a throat and a diverging section. The nozzle bodies are so adjustable that streams of fluid at maximum velocity for a multi-phase fluid having particular characteristics as to heat, pressure and water droplet content discharge tangentially onto the two sets of spaced discs to flow through the spaces therebetween in spiral paths to discharge through openings in the centers thereof. The fluid as it pursues a spiral path exerts a drag on the discs, with the fluid losing kinetic energy that is transferred to the discs, rotor plate and shaft to drive them as an integral unit. No substantial lateral force is exerted on seals in the turbine as the lateral force generated by one set of discs by pressurized fluid flowing through the spaces therebetween is cancelled out by a like and opposite force generated on the other set of discs by the fluid.
