Latest Patents
Andrew's notable patent is titled "Ultra high pressure turbomachine for waste heat recovery." This invention introduces a turbine-driven alternator suitable for generating electrical power from process gas waste energy. Specifically, it is designed to work with high-density process gases such as super critical CO2, R134a, and R245fa. The turboalternator consists of two distinct components: a turbine device and an alternator device, which are connected via a coupling shaft. The design employs hydrodynamic foil gas bearings, which utilize process gas for high-pressure operations, allowing for thrust load balancing and efficient functionality at pressures around 3000 psia. On the alternator side, cooling fluid is used in the foil gas bearings, facilitating high-speed operations (up to 40,000 rpm) while ensuring an oil-free and low-windage environment through closed-loop shaft cooling.
