The Application of FT-IR Spectroscopy to Turbine Engine Exhaust Measurement
Abstract
An advanced multiple gas analyzer based on Fourier transform infrared (FT-IR) spectroscopy has been used to successfully measure the exhaust composition from a gas turbine engine combustors rig at the Arnold Engineering Development Center (AEDC), Arnold Air Force Base (TN). The advanced FT-IR multigas analyzer was able to demonstrate its ability to not only measure the species traditionally measured at the facility (water, CO2, CO, NO, NO2, and total hydrocarbons), but also to measure many other species, including sulfur dioxide, formaldehyde, ethylene, propylene, methanol, formic acid, and nitrous acid. A side by side comparison of the single gas analyzers currently employed by AEDC and the FT-IR Multigas analyzer showed good agreement. The capability of a single relatively low-cost, small sized Multigas analyzer to measure most of the important products of combustion makes it an attractive alternative to existing emissions measurement systems. The Multigas analyzer may he used to measure the exhaust gas composition of aircraft engine combustors that are regulated by the FAA as well as stationary source engines that are regulated by the EPA.
