Abstract: Heat flow from a steam seal header could be used in a stage, such as a low pressure stage, of a steam turbine. However, the dump steam temperature from the steam seal header can be too high requiring removal of excess heat, typically through attemperation, before the dump steam is provided to the low pressure stage. Attemperation poses reliability and life issues and lowers efficiency. To address such short comings, one or more heat pumps are used to transfer heat from the dump steam to the fluid entering a boiler. This allows the dump steam temperature to be within acceptable limits, and at the same time, increase the temperature of the fluid so that the steam cycle performance is enhanced. Preferably, solid-state heat pumps are used as they are reliable, silent and can be precisely controlled.

Abstract: A system and method for monitoring the condition of a gear assembly analyzes a signal output by a vibration detector that is attached to the gear assembly. Each time that an amplitude of the signal output from the vibration detector exceeds a threshold value, the system assumes that a debris particle has passed between meshing parts of the gear assembly. The number of times that this occurs, and possibly the amplitude of the vibrations are analyzed to determine a condition of the gear assembly, and possibly a damage index. This system and method are particularly applicable to planetary gear arrangements where the vibration detector can be mounted on a fixed ring gear of the gear assembly, or a structure upon which the fixed ring gear is mounted.
