【摘要】：为深入研究燃气轮机燃用生物柴油对其燃烧与排放性能的影响,将生物柴油与柴油按照不同比例进行混合,在双旋流燃烧室90°扇形试验件上进行降压模拟燃烧试验.结果表明:随油气比的增加,燃烧效率和NOx排放快速增加并趋于稳定,出口温度分布系数(OTDF)、径向分布系数(RTDF)、CO排放逐渐减小并趋于稳定;随生物柴油混合比例的增加,燃烧效率、燃烧室温升逐渐降低,OTDF和NOx排放先减小后增加,RTDF和CO排放逐渐增加.随油气比的增加,生物柴油对燃烧和排放的主要影响方面发生变化,影响程度逐渐减弱,不同油气比时存在不同的最佳生物柴油混合比例.
[Abstract]:In order to study the effect of biodiesel on combustion and emission performance of gas turbine, the pressure reduction simulation combustion test was carried out on 90 掳fan test piece of double swirl combustor by mixing biodiesel and diesel fuel in different proportion. The results show that the combustion efficiency and NOx emission increase rapidly and tend to be stable with the increase of oil / gas ratio. The outlet temperature distribution coefficient (OTDF), radial distribution coefficient (RTDF), CO emission decreases gradually and tends to be stable. With the increase of the ratio of biodiesel, the combustion efficiency and temperature rise of combustion chamber decrease gradually, the emissions of OTDF and NOx decrease and then increase, and the emissions of RTDF and CO increase gradually. With the increase of oil / gas ratio, the main effect of biodiesel on combustion and emission changes, and the influence degree gradually weakens, and the best ratio of biodiesel is different with different oil / gas ratio.
