Results show that all the geometric parameters have remarkable effects on combustion performance ; the swirl of intake air generated by skew intake holes enhances fuel - air mixing, minimizes dead zone and stabilizes the flame with reverse flow, but the excessive reverse flow can cause overheat in combustion chamber and exhaust ; the consistency of flow resistance in intake and exhaust system is conducive to the stability of heater performance
研究表明,燃燒室進氣孔的孔徑、孔數、孔的分佈及方向等均對燃燒性能影響很大;斜孔所產生的旋轉進氣,雖具有強化燃氣混合、消除死區和迴流穩焰的作用,但迴流過度會使燃燒室及排溫過高;保證進排氣系統流動阻力(壓力)的一致性,有助於保證加熱器性能穩定。Effects of different fuel - air ratios and different geometric parameters of dual - stage swirler ( such as inner diameters of the primary swirl and secondary swirl passages, outer diameters of the secondary swirl passages, vane angle of the primary and secondary swirler, the distance of the flare exit from throat etc ) on combustion performances are studied experimentally. the experimental results show that radial profiles of the outlet gas temperature 、 combustion efficiency 、 emissions of co2 、 co and nox and lean blowout are affected with different degrees by the different geometric parameters of dual - stage swirler and the arrangement of primary holes
在不同油氣比下,不同的雙級旋流器幾何參數(例如:一級與二級旋流器出口內徑d 、葉片安裝角、二級旋流器出口外徑d 、二級旋流器的喉道到出口截面的距離l和喉道前後的圓弧半徑r以及主燃孔孔布局等)對單頭部環形燃燒室的出口溫度分佈、燃燒效率、貧油熄火油氣比以及污染物( co _ 2 、 co和nox )排放等燃燒性能的影響規律進行了研究。
