We discuss the effect of stretch rate on the flame structure, the burning velocity and the burning rate in premixed counter flow flat flame. Numerical computations taking into account detailed chemical kinetics and multi-component diffusion are conducted. The burning velocity increases with increasing the stretch rate. But, the burning rate decreases with increasing the stretch rate. Usually, we think the burning velocity matches to complete burnt fuels. But, according to the numerical computations, it is found that the fuel of burning velocity isn't completely burnt. Nearly 40% spilt away. Premixed combustion has the larger combustion rate than the diffusion flame and can burn the gas wider than unburned stoichiometry.
