Abstract: A drop-in nozzle block (40) formed in two 180° segments (52) that can be simply lowered into position within the nozzle chamber casing of a steam turbine (42). An entire 180° segment can be lowered into position because an inner arcuate portion (58) of the nozzle block fits over and captures mating portions of the casing rather than having the casing capture the nozzle block as in the prior art. Elimination of a hook portion of the casing eliminates the necessity for the prior art procedure of rotating 90° segments into position through an arcuate-shaped slot. The drop-in installation allows closer tolerances to be maintained between the nozzle block and the casing, thereby eliminating the need for the expansion pins used in the prior art. The use of two 180° segments rather than the prior art 90° segments also eliminates the need for a dogleg joint between segments for turbines having eight steam inlet segments.

Abstract: A valve for reducing fluid pressure in a fluid distribution network uses the energy released from the fluid to generate power. The valve includes a housing, a turbine disposed within the housing, a fluid reservoir, and a flow control device operable to generate a turbine inlet flow having a flow velocity from an inlet flow having a fluid pressure. The turbine receives the turbine inlet flow, which rotates the turbine to generate power. The fluid reservoir collects the flow of fluid discharged from the turbine and generates a valve discharge flow having a desired fluid pressure that is less than the fluid pressure of the inlet fluid. Thus, the energy from the inlet flow is used to generate power. Furthermore, the power generated by the turbine can be independent of the fluid pressure of the valve discharge flow. Consequently, the valve can provide a consistent reduction in fluid pressure and/or flow rate in a distribution network while the turbine generates power.

Abstract: A drop-in nozzle block (40) formed in two 180° segments (52) that can be simply lowered into position within the nozzle chamber casing of a steam turbine (42). An entire 180° segment can be lowered into position because an inner arcuate portion (58) of the nozzle block fits over and captures mating portions of the casing rather than having the casing capture the nozzle block as in the prior art. Elimination of a hook portion of the casing eliminates the necessity for the prior art procedure of rotating 90° segments into position through an arcuate-shaped slot. The drop-in installation allows closer tolerances to be maintained between the nozzle block and the casing, thereby eliminating the need for the expansion pins used in the prior art. The use of two 180° segments rather than the prior art 90° segments also eliminates the need for a dogleg joint between segments for turbines having eight steam inlet segments.

When mounted externally to an aquarium, proper placement of output nozzles, which are connected to a water conduit attached to the various SCWD outlet ports, provides the desired opposing, or switching back and fourth currents. Depending on the inlet and outlet port configuration, the SCWD can be adapted to suit many applications.

Abstract: The preferred embodiment of the disclosed condensing turbine is characterized by its tolerance to fully condensing working fluid vapor and a unique geometry that uses a naturally developed centrifugal force, generated by the working fluid, along with an integral positive displacement pump, to return the working fluid to a vapor generator in a high pressure liquid state. Thus, with the working fluid exiting the turbine in a highly pressurized liquid state rather than a low pressure vapor state, the requirement for a conventional condenser, condensate pump and boiler feed pump is eliminated. This unique combination of turbine and positive displacement pump, exemplified by the present invention, allow the closed-loop vapor cycle turbine engine to become very compact and, thus, practical for automotive and aerospace use.
