Development of TDLAS sensor for diagnostics of CO, H2O and soot concentrations in reactor core of pilot-scale gasifier

This paper reports on the development of the tunable diode laser absorption spectroscopy sensor near 4350 cm −1 (2298 nm) for measurements of CO and H 2 O mole fractions and soot volume fraction under gasification conditions. Due to careful selection of the molecular transitions [CO ( υ ″ = 0 →  υ ′...

Zusammenfassung:This paper reports on the development of the tunable diode laser absorption spectroscopy sensor near 4350 cm −1 (2298 nm) for measurements of CO and H 2 O mole fractions and soot volume fraction under gasification conditions. Due to careful selection of the molecular transitions [CO ( υ ″ = 0 →  υ ′ = 2) R34–R36 and H 2 O at 4349.337 cm −1 ], a very weak (negligible) sensitivity of the measured species mole fractions to the temperature distribution inside the high-temperature zone (1000 K
