Abstract
A compact axial turbine configured to operate with high density working fluid is described. The turbine comprises an axial majority cantilevered turbomachinery shaft. Rotor assemblies and nozzle spacers communicate torque through turbine shaft splines, allowing them to be slid off the shaft for quick replacement in the field. The compact axial turbine houses turbomachinery within a separable inner casing encircled by a cartridge sleeve, thereby forming a cartridge which can itself be removed as a single component.
Claims20
A compact axial turbine comprising:
- two or more rotor assemblies comprising a plurality of torque carrying splines;
- a turbomachinery shaft comprising an output shaft and a torque carrier tube;
- wherein the output shaft comprises a plurality of torque carrying splines, wherein torque carrier tube comprises a plurality of torque carrying splines, and wherein at least a portion of the torque carrying splines of the output shaft are meshed with at least a portion of the torque carrying splines of the torque carrier tube;
- and
- wherein at least a portion of the torque carrying splines of the torque carrier tube are meshed with the torque carrying splines of the two or more rotor assemblies.
A compact axial turbine comprising:
- two or more rotor assemblies comprising a plurality of torque carrying splines;
- a turbomachinery shaft, wherein the turbomachinery shaft comprises a plurality of torque carrying splines configured to mesh with the torque carrying splines of the two or more rotor assemblies;
- a nozzle spacer;
- wherein the nozzle spacer comprises a plurality of torque carrying splines configured to mesh with the torque carrying splines of the turbomachinery shaft.
A compact axial turbine comprising:
- turbomachinery disposed in an inner casing, wherein the inner casing is separable along a longitudinal axis of the turbine into two or more segments;
- a turbine cartridge sleeve surrounding an axial majority of said inner casing, wherein said turbine cartridge sleeve holds together the two or more segments of the inner casing;
- and
- a torque carrier tube, wherein an axial majority of said torque carrier tube is cantilevered.
