【摘要】：為解決高溫升燃燒室點(diǎn)火、慢車工況的燃燒穩(wěn)定性與起飛、巡航工況下高效率低冒煙燃燒之間的矛盾,對采用中心分級技術(shù)的雙級旋流多點(diǎn)噴射直接混合(TAMDIM)組織燃燒技術(shù)的單頭部燃燒室進(jìn)行了試驗(yàn),試驗(yàn)狀態(tài)為慢車、起飛、亞聲速巡航。通過試驗(yàn)獲取了各個工況下燃燒室的燃燒效率、火焰筒壁溫分布及冒煙值。TAMDIM燃燒室除慢車工況的燃燒效率小于0.99外,其余工況的燃燒效率均大于0.995,采用燃油分級對燃燒室效率影響很小。多斜孔發(fā)散冷卻有良好的冷卻能力,使得火焰筒壁溫在燃燒室溫升1157K下僅1005K。燃燒室在高油氣比狀態(tài)下冒煙數(shù)小于10,滿足ICAO規(guī)定的要求。
[Abstract]:In order to solve the contradiction between combustion stability and take-off in the combustion chamber of high temperature lift, high efficiency and low smoke combustion under cruising condition. The single-head combustion chamber with two-stage swirl multi-point injection direct mixing (TAMDIMI) tissue combustion technology using central classification technology was tested. The test state was a slow train and took off. The combustion efficiency of the combustor was obtained by experiments. The combustion efficiency of the combustion chamber was less than 0.99 except for the slow-train condition, and the combustion efficiency of the combustion chamber was less than 0.99 except for the flame cylinder wall temperature distribution and smoke emission. The combustion efficiency of the other conditions is greater than 0.995.The fuel classification has little effect on the efficiency of the combustion chamber. The multi-slant hole divergent cooling has a good cooling capacity. The wall temperature of the flame cylinder increases only 1005K at 1157K, and the number of smoke in the combustor is less than 10 under the condition of high oil / gas ratio, which meets the requirement of ICAO.
