Abstract

AbstractThe performance of an apodized gas sensor is demonstrated through simultaneous detection of CO and CO2 absorption lines around 1.57 µm in the recuperator channel of a gas-fired industrial furnace at Shahid Montazeri power plant (SMPP) industry. This led to the concentration measurement of targeted molecules as less thanâ~â1% and 9.5%, respectively, at atmospheric pressure and 350 °C, indicating close consistency with the reference data reported by SMPP. A minimum detectable absorption ofâ~â0.4âÃâ10â3, corresponding to a detection sensitivity ofâ~â4.8âÃâ10â9 cmâ1 Hzâ1/2 is measured in this application.
