Research Abstract

Assuming coal gasification syngas combustion, turbulent premixed flames for the mixtures of CO/H2 and air as well as pure O2 diluted with large amount of CO2 were stabilized in a high pressure environment and the measurement of turbulent burning velocity, mean volume of turbulent flame region, flame surface density, radiation intensity, etc. were performed. It was proven that structure of turbulent flame region became very fine, being related the change in flame surface density and mean flame volume, and the radiation intensity became strong.
