coal-fired boiler monitoring work

Real-time in situ continuous monitoring of CO in a ...

Nov 21 2012 · A real-time in situ CO sensor using 2.3 m DFB diode laser absorption with calibration-free wavelength-modulation-spectroscopy was demonstrated for continuous monitoring in the boiler exhaust of a pulverized-coal-fired power plant up to temperatures of 700 K. The sensor was similar to a design demonstrated earlier in laboratory conditions now refined to accommodate the harsh
