Latest Patents
Bien's latest patents showcase his innovative approaches to enhancing combustion efficiency. One of his recent inventions is a "Combustor control based on fuel modulation and passive optical sensors." This system controls the uniformity of combustion across varying operating conditions in a combustor containing multiple fuel nozzles. It includes several optical sensors that collect naturally occurring optical radiation from the combustor and its exhaust. The transducers analyze the intensity of this radiation across different spectral pass-bands, which reflect the fuel/air ratio, and produce output signals. These signals guide a control system to adjust fuel flow to achieve optimal combustion states.
Another of his notable inventions is a "System and method for optically determining properties of hot fluids from the spectral structure of emitted radiation." This system enables remote determination of temperature and relative species concentrations in hot fluids by analyzing the spectral structure of emitted radiation. By collecting thermal radiation across a field of view, this method provides critical insights into the thermodynamic properties of hot fluids by resolving their emission spectrum.
