Transformation of Nitrogen Oxides while Sampling Combustion Products.
Abstract
The objective of the program was to assess the condition under which transformations of nitrogen oxides (NO and NO2) may occur in an extractive probe used to sample exhaust gases from combustor sources such as gas turbine engines and boilers. The approach was to use simulated combustion products in a controllable laboratory experiment. Trials were run using 2-meter (79-inch) long, 6.35 mm (0.25-inch) OD tubing. Tubing materials considered included type 316 stainless steel, quartz, inconel, and nickel. Various gaseous compositions, including those representative of gas turbine exhausts, were evaluated for various temperatures over a range (150 C to 400 C) typical of the temperatures experienced by probe materials in practical systems. NOx is conserved in 316 stainless steel and quartz tubes up to 400 C. Above 400 C, NOx can be destroyed. Originator supplied keywords include: Exhaust sampling; Combustion; Exhaust composition.
