Abstract
Coherent Anti-Stokes Raman Spectroscopy (CARS) is a laser based advanced combustion diagnostic technique and is being used to measure the temperature and major species concentration in a turbulent, harsh, high luminescence and reactive combustion environment.1 Recently, it has also been applied to a Coal Fired Flow Facility (CFFF), which is a unique practical combustion environment.2 Only a few CARS applications to chemical reaction have been reported. One of the important chemical reactions is a chlorination reaction. CH4 + Cℓ2 → CH3Cℓ + HCℓ. This is being used to manufacture the halogenated hydrocarbon. HCℓ is one of the product species in the reaction. So, there is a possibility to apply the multiplex HCℓ CARS spectrum for temperature measurements in a chemical reactor. This type of measurement should provide the information about mixing of CH4 and Cℓ2 and also the completion of the reaction.
