Temperature-corrected spectroscopic evaluation method for gas concentration monitoring
Författare
Summary, in English
Combustion exhaust monitoring was simulated by measurement on a sulfur dioxide flow at different temperatures using broadband absorption spectroscopy and electrochemical analysis. A linear relationship with varying rates of slope for different temperatures was found between the gas concentrations obtained using the two methods, attributed to the influence of gas volume increase and absorption line broadening. By utilizing the differential absorption at an on/off pair combined with an experimentally determined temperature correction coefficient, the sulfur dioxide concentration was evaluated with the spectroscopic method yielding a measurement precision of 4%.
