Latest Patents

One of his latest patents is for a steam generator with an axial flow preheater. This invention features an improved heat exchanger that utilizes a primary heated fluid to vaporize a secondary fluid flowing axially through it. The design includes a preheater assembly located within the cold leg side of the heat exchanger, allowing for efficient heating of the secondary fluid to its boiling point. The heat exchanger comprises a vertical shell portion with a tubesheet and a tube bundle containing U-shaped tubes for the primary fluid. The preheater assembly enhances heat transfer by introducing cold water near the coldest end of the tubes, preventing thermal shock to the tubesheet.

Another significant patent by Chan discloses a secondary fluid supply system for a steam generator used in nuclear reactor power plants. This system includes a secondary fluid inlet nozzle near the base of the steam generator shell and a feedwater riser pipe that connects to a distribution ring with multiple spray nozzles. This innovative design ensures effective distribution of feedwater in the recirculating pool above the heat exchanger tubes.
