Download or read book Near-infrared Diode Laser Absorption Spectroscopy with Applications to Reactive Systems and Combustion Control written by Hejie Li and published by . This book was released on 2007 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detailed experiments are conducted to optimize the sensor position for thermoacoustic instability and lean blowout (LBO) detection in a swirl-stabilized combustor using a real-time TDL temperature sensor. The intensity of low-frequency fluctuations is used to detect the proximity to LBO and as a control variable for active LBO suppression without knowing the LBO equivalence ratio limit.
