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.

假设燃煤气化合成剂燃烧，在高压环境中稳定了CO/H2和空气混合物的湍流混合火焰以及用大量CO2稀释的纯O2，并测量了湍流燃烧速度的测量，平均湍流火焰区域，湍流区域，火焰表面密度，辐射强度等。事实证明，湍流区域的结构变得非常好，与火焰表面密度和平均火焰体积的变化相关，并且辐射强度变得强大。
