With a total of 4 patents to his name, Lee's work showcases his expertise and innovative spirit.
Latest Patents
One of his latest patents is a conductivity sensor designed for use in steam turbines. This sensor is specifically created for placement on a curved steam turbine component within the steam path. It features a metal foil base over which an electrically insulating layer, such as glass, is deposited. The design allows for flexibility, enabling it to conform to the curved surface of the turbine. An electrode array is deposited upon the insulating layer, spaced to accommodate the deposition of steam impurities. Flexible links connect the electrodes to electrical leads, allowing for conductivity indications to be obtained.
Another significant patent by Lee is a method and apparatus for preventing the deposition of corrosive salts on turbine systems. This innovative system includes a reheater positioned upstream from a low-pressure turbine, which is susceptible to corrosive salt depositions from the steam. Conductance probes are strategically inserted within the low-pressure turbine. Based on the conductance signals received, the reheat temperature or load is adjusted to move the corrosive salt deposition zone away from the rotating blade stage of the turbine.
