摘　　要：针对某型辅助动力装置全环形燃烧室开展了整机燃烧性能试验研究。采用温度耙测量全环形燃烧室出口温度分布,研究不同进口温度和油气比条件下辅助动力装置燃烧室整机燃烧性能。试验结果表明:随着进口温度和油气比的增加,燃烧室出口温度相应增加,但温度分布规律基本保持不变,出口温度分布系数(OTDF)小于0.2,径向温度分布系数(RTDF)基本小于0.1,而燃烧效率和燃烧室进出口压力损失系数增加;随着进口总温的增加,燃烧室贫油熄火油气比逐渐减少(余气系数增加),但燃烧室的贫油熄火余气系数均大于13。Experimentally studied was the whole-machine combustion performance of a wholly annular combustor of an auxiliary power plant.A temperature rake was used to measure the temperature distribution at the outlet of the combustor and investigate the whole-machine combustion performance of the combustor under discussion at various inlet temperatures and oil/gas ratios.The test results show that with an increase of the inlet temperature and oil/gas ratio,the temperature at the outlet of the combustor will increase accordingly,however,the temperature distribution law will basically keep unchanged.The outlet temperature distribution factor(OTDF) will be less than 0.2 and the radial temperature distribution factor(RTDF) will be basically less than 0.1 while the combustion efficiency and the pressure loss coefficient at both inlet and outlet of the combustor will increase.With an increase of the total temperature at the inlet,the oil/gas ratio,at which a flame extinguishment will occur to the combustor due to a lack of oil,will decrease gradually(air excess coefficient will increase),however,all the air excess coefficients will be more than 13 when a flame extinguishment occurs to the combustor due to a lack of oil.
