Parametric Study of Temperature Field of Impinging Burner of Synthetic Gas by Interferometry Mach-Zehnder Method

In this study temperature and flame structure of synthetic gas of two impinging slot burner were investigated experimentally by the Mach-Zehnder interferometry method. The main objective of the study was to examine the key parameters including Reynolds number of jet flow and input fuel and their equivalence ratio on combustion. For the first step, the experimental results of temperature distribution were compared to measured data by thermocouples and maximum and minimum error of 8% and 3% were observed. Temperature Contour and temperature distribution in different sections have been extracted and analyzed. The results show that although the Reynolds number does not affect on the maximum temperature, it has a great influence on the flame structure. Thus, increasing the number of Reynolds increases the region of reaction in the line of symmetry, increases the number of Fringe lines and extends the heated region. Changes in the equivalence ratio directly affect the structure of the flame, thus an increase of this parameter shift the flame zone to downstream and flame stability decreases.
