  • Patent number: 10052667
    Abstract: A method of cleaning a vessel having deposits on an interior surface includes removably bonding an ultrasonic transducer to an external wall of the vessel and using the ultrasonic transducer to produce ultrasonic energy coupled into the vessel wall such that at least a portion of the ultrasonic energy is transmitted to the interior surface.
    Type: Grant
    Filed: March 14, 2014
    Date of Patent: August 21, 2018
    Assignee: Dominion Engineering, Inc.

  • Patent number: 9841184
    Abstract: A method is provided for evaluating simultaneously the effects of multiple, interdependent heat-exchanger degradation modes for a heat exchanger of a power plant in the context of a series of alternative heat-exchanger remediation strategies. The method includes calculating time-varying predicted future progressions of heat exchanger performance metrics for a plurality of alternative heat-exchanger remediation strategies, and calculating time-varying predicted future progressions of financial metrics describing the accumulated financial benefit of each of the strategies. The calculations may be provided in probabilistic terms. A strategy may then be chosen based, at least in part, on the calculated results.

  • Patent number: 5913320
    Abstract: An improved remotely-operated high-pressure water-jet sludge lancing system for removing sludge from the secondary side of steam generators, the system including an end effector and a deployment system. The end effector includes two diametrically opposed articulated nozzle heads having water jet nozzles attached thereto. The nozzle heads are pivotally mounted to respective pneumatic extension arm actuators that are accommodated in respective arms. The arms are attached in a collinear relation to opposing sides of a centrally located drive means, which allows for the rotational positioning of the nozzle heads. The deployment system for delivering and supporting the end effector includes a self-erecting load-bearing chain and a segmented support rail having a straight section and a curved section. The chain is suspended from the support rail by hangers and cylinder rollers.
