Book Emission Spectrum of Nitric Oxide in the Near Infrared

Download or read book Emission Spectrum of Nitric Oxide in the Near Infrared written by Eugene Franklin Horn and published by . This book was released on 1963 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nitric oxide emission spectrum of the vibrationrotation bands of the electronic ground state has been observed in the 1.83-195 micron and 2.63-2.81 micron regions. A high tension discharge through NO at reduced pressure was utilized as the source. The 2.69, 2.73, and 2.77 micron bands were analyzed in detail and accurate values of the vibrational and rotational constants and the spin-orbit coupling constant A are presented. A calibration procedure utilizing atomic spectral lines was developed for use with the high-resolution grating spectrometer employed in the study. A detailed analysis of the applicability of the procedure is presented. (Author).

Book UV Absorption Measurements of Nitric Oxide Compared to Probe Sampling Data for Measurements in a Turbine Engine Exhaust at Simulated Altitude Conditions

Download or read book UV Absorption Measurements of Nitric Oxide Compared to Probe Sampling Data for Measurements in a Turbine Engine Exhaust at Simulated Altitude Conditions written by R. Howard and published by . This book was released on 1997 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitric oxide measurements were conducted in the exhaust of a turbofan engine at simulated altitude conditions in a ground-level test cell using both optical nonintrusive and conventional gas sampling techniques. NO-UV absorption measurements, using both resonance and continuum lamps, were made through several chords of the exhaust flow near the nozzle exit plane as a part of a larger effort to characterize aircraft exhaust constituents over a wide range of steady-state engine operating conditions. This paper describes the NO-UV absorption measurements and compares radial profiles of NO concentrations and emission indices with measurements obtained using conventional gas sampling and tunable diode laser infrared absorption.

Book Development of All Solid State Sensors for Measurement of Nitric Oxide and Ammonia Concentrations by Optical Absorption in Particle Laden Combustion Exhaust Streams

Download or read book Development of All Solid State Sensors for Measurement of Nitric Oxide and Ammonia Concentrations by Optical Absorption in Particle Laden Combustion Exhaust Streams written by Robert P. Lucht and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An all-solid-state continuous-wave (cw) laser system for ultraviolet absorption measurements of the nitric oxide (NO) molecule has been developed and demonstrated. For the NO sensor, 250 nW of tunable cw ultraviolet radiation is produced by sum-frequency-mixing of 532-nm radiation from a diode-pumped Nd:YAG laser and tunable 395-nm radiation from an external cavity diode laser (ECDL). The sum-frequency-mixing process occurs in a beta-barium borate crystal. The nitric oxide absorption measurements are performed by tuning the ECDL and scanning the sum-frequency-mixed radiation over strong nitric oxide absorption lines near 226 nm. In Year 1 of the research, the nitric oxide sensor was used for measurements in the exhaust of a coal-fired laboratory combustion facility. The Texas A & M University boiler burner facility is a 30 kW (100,000 Btu/hr) downward-fired furnace with a steel shell encasing ceramic insulation. Measurements of nitric oxide concentration in the exhaust stream were performed after modification of the facility for laser based NOx diagnostics. The diode-laser-based ultraviolet absorption measurements were successful even when the beam was severely attenuated by particulate in the exhaust stream and window fouling. Single-laser-sweep measurements were demonstrated with an effective time resolution of 100 msec, limited at this time by the scan rate of our mechanically tuned ECDL system. In Year 2, the Toptica ECDL in the original system was replaced with a Sacher Lasers ECDL. The mode-hop-free tuning range and tuning rate of the Toptica ECDL were 25 GHz and a few Hz, respectively. The mode-hop-free tuning range and tuning rate of the Sacher Lasers ECDL were 90 GHz and a few hundred Hz, respectively. The Sacher Lasers ECDL thus allows us to scan over the entire NO absorption line and to determine the absorption baseline with increased accuracy and precision. The increased tuning rate is an advantage in that data can be acquired much more rapidly and the absorption measurements are less susceptible to the effects of transient fluctuations in the properties of the coal combustor exhaust stream. Gas cell measurements were performed using the NO sensor with the new ECDL, and a few spectra were acquired from the coal exhaust stream. However, the laser diode in the new ECDL failed during the coal combustor tests. In Year 3, however, we obtained a new GaN laser diode for our ECDL system, installed it, and completed an extensive series of measurements in the Texas A & M coal-fired laboratory combustion facility. The combustor was operated with coal and coal/biomass as fuels, with and without reburn, and with and without ammonia injection. Several different fuel equivalence ratios were investigated for each operating condition.
