Characteristic of Low Calorific Fuel Gas Combustion in a Pressurized Porous Burner

Abstract:

Combustion characteristic of low calorific fuel gas in a pressurized porous burner was numerically investigated. The two-dimensional temperature profile, flame front, and CO concentration distribution were analyzed under the pressure at the certain operating parameters, and compared with those of the normal pressure. The results shows that the pressured temperature profile is more clear than that of the normal pressure, and maximum temperature distribution region is larger. Compared with the normal pressure, the pressured flame front location is at the downstream, and the flame propagation velocity along with inclination increases with the pressure increasing. The CO distribution is corresponding to the temperature profile. Its maximum locates at the position of the flame front, and gradually decreasing along the axial direction. It decreases with the pressure increasing, which indicates that the pressure contributes to improve the combustion efficiency.
