Fast Nitrogen Dioxide Reactions: Significance during NO Decomposition and NO₂Formation

Abstract

5imple mechanisms are proposed for both NO decomposition and NO, formation at typical combustion conditions. Analytical studies indicate that the fast NO, reactions, NO, + M ;!: NO + 0 + M and NO

Mechanism Research and Countermeasure Analysis of Yellow Plume during the Gas Turbine Start-Up Period

“…Tuttle, Shisler and Mellor [3] studied the yellow plume phenomenon of gas turbine exhaust, showing that the emitted nitrogen oxides contained more NO 2 . Laurendeay [4] proposed simple mechanism conditions for NO decomposition and NO 2 formation in typical combustion. Chen [5] found that the higher is the CH 4 ratio, the higher is the proportion of NO 2 in the product NOx by changing the ratio of H 2 -CH 4 in the fuel.Klaus [6] and others conducted studies on the spectral measurement of NOx and successfully developed a system that can measure gas turbine exhaust.…”

Probe Effects in Gas Turbine Combustor Emission Measurements

“…A 1974 study using cooled stainless probes in conjunction with both the chemiluminescent and non-dispersive ultraviolet techniques for detecting NO,, concluded that NO 2 formation in probes was possible, but could not be easily proved (4). Several researchers subsequently argued that the formation of NO 2 both in flames and in sampling probes was due to the rapid temperature quench of gases containing NO, atomic oxygen, and HO 2 (4,5,6,7,8,9).…”
