  • Patent number: 5971702
    Abstract: A rotary machine, such as a compressor, includes a casing having an annular cavity. The cavity is stepped to include a first circumferential surface of a first size and a second circumferential surface of a second size, less than the first size. At least one roller member is retractably mounted in the casing and is adjustable between a first position and a second position. In the first position, the roller member is retracted from the cavity and is substantially aligned with first circumferential surface. In the second position, the roller is extended into the cavity and substantially aligned with the second circumferential surface. When extended, the roller member can support a reduced diameter portion of a compressor bundle substantially in alignment with the second circumferential surface of the cavity during insertion of the compressor bundle into, or removal of the compressor bundle from the cavity in the compressor casing.

  • Patent number: 5087172
    Abstract: A high pressure compressor seal having an inner part and an outer part rotatable with respect to each other. The inner seal part includes a polygonal-shaped bore mounted on a polygonal-shaped compressor shaft. The outer seal part has plural O-rings therearound, and is sealed within a compressor housing opening. The outer seal part includes slots formed within an end face thereof for engagement with stationary compressor vanes, thereby preventing rotation of the outer seal part.

  • Patent number: 4961260
    Abstract: A high pressure compressor seal assembled onto a compressor shaft, together with compressor bundle elements. A stationary bundle vane is engaged with slots within the seal to prevent rotation of an outer portion of the seal during operation of the compressor. In addition, the stationary vanes engage groves in the seal so that when the bundle elements are inserted into the compressor, the seal can be pushed into a housing opening.

  • Patent number: 4452048
    Abstract: The load on the starting steam turbine or motor which drives the power recovery string of an FCC process is reduced on the order of 15% by increasing the specific volume of the air compressed by a fixed volume compressor in the string. The specific volume of the ambient air is increased by returning a portion of the compressed and thereby heated air to the inlet of the compressor in amounts sufficient to raise the temperature of the inlet air about 75.degree. F., or more.

  • Patent number: 4352024
    Abstract: An expander driven by waste heat fluid is operatively connected to a synchronous or induction generator. A brake/clutch controller selectively connects the power recovery string to an eddy current brake/flywheel in order to maintain line frequency and control speed during normal conditions and to minimize acceleration of the string during a load dump.

    Assignee: Carrier Corporation
    Inventors: Carl H. Geary, Norman A. Samurin
  • Patent number: 4191485
    Abstract: A wheel of a turbo-machine is secured to the shaft of the machine by forming a side of the wheel with an end cap affixed thereto. Compressive force generating means connected to the end cap generate a force for compressing the wheel between the end cap and shaft.

  • Patent number: 4189156
    Abstract: A seal system for a turbomachine employing first fluid as a working medium and utilizing the same fluid in its liquid phase as a sealing medium. The pressure of the liquid sealing medium is maintained above the pressure of the working medium. The fluid is delivered to a first sealing region whereat the fluid flows in opposite directions along the shaft of the turbomachine, respectively towards the ambient and towards the working region in the machine. A seal is interposed between the first sealing region and the ambient to prevent the seal fluid from intermixing with air.
