【摘要】：本文將開縫鈍體穩(wěn)燃技術(shù)應用于微型燃燒器中,采用詳細化學反應機理模擬了不同速度下微型開縫鈍體燃燒器與微型常規(guī)鈍體燃燒器的燃燒情況.結(jié)果表明:開縫鈍體燃燒器火焰寬度一致性較好,火焰中心溫度沿軸向分布更加均勻,尤其在速度較大時,開縫鈍體燃燒器優(yōu)勢更加明顯;開縫鈍體燃燒器燃燒效率高于常規(guī)鈍體燃燒器,速度大于25m/s時,開縫鈍體燃燒器效率高出常規(guī)鈍體燃燒器5%左右;由于開縫鈍體中鈍體縫隙過大,瀕臨吹熄極限時,鈍體后值班火焰被吹熄,開縫鈍體燃燒器吹熄極限略有降低.
[Abstract]:In this paper, the slit blunt body steady combustion technology is applied to the micro burner. The combustion of the micro slit obtuse body burner and the micro conventional blunt body burner at different velocities are simulated by using the detailed chemical reaction mechanism. The results show that the flame width of the slit blunt body burner is consistent and the flame center temperature is more uniform along the axial direction, especially when the velocity is higher, the advantage of the slit blunt body burner is more obvious. The combustion efficiency of the slit blunt body burner is higher than that of the conventional blunt body burner. When the speed is higher than that of the conventional blunt body burner, the efficiency of the slit blunt body burner is about 5% higher than that of the conventional blunt body burner. The flame on duty after the blunt body is blown out, and the blowout limit of the slit blunt body burner is slightly reduced.
