| 摘 要： | 本文通过实验研究了在保持微型燃气轮机燃烧室出口排气温度不变的情况下,改变进口空气温度对燃烧室燃烧特性的影响.结果表明,随着燃烧室进气温度的增大,燃烧效率提高,燃烧室出口温度不均匀性系数减小,热阻增大,总压恢复系数有所降低.同时,实验结果还表明,随着燃烧室进口空气温度的增大,燃烧室出口处CO及未燃烬碳(UHC)排放浓度显著降低,但NO排放浓度则增大.根据实验结果,本文还分析了进气温度的改变对燃烧室燃烧特性的影响规律,为今后微型燃气轮机燃烧室的研制及改进提供了参考依据.

| Abstract: | Experimental studies were conducted to investigate effects of the inlet temperature on the combustion characteristics within a micro gas turbine combustor under the condition of keeping the same exhaust temperature.The results show that,with increasing of the inlet temperature,the com- bustion efficiency increased,while the outlet temperature fluctuation coefficient and the total pressure recovery factor reduced.The emissions of CO and unburned hydrogen carbon (UHC) significantly re- duced,but the emission of NO significantly increased with increase of the inlet temperature.Moreover, the combustion characteristics of the micro gas turbine combustor were further analyzed according to the experimental data.These experimental results are of significance for the design and retrofit of the micro gas turbine combustor. |
