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

An experimental study was conducted by using different mixing ratios of biodiesel fuels and diesel oil on an angle 90° double swirler combustor under simulative pressure condition to investigate the influence of biodiesel fuels on the combustor performance and emissions of gas turbine. The experimental results show that with the increment of fuel-air ratio

the combustion efficiency and NOx emissions increase

and the outlet temperature distribution factor(OTDF)

radial temperature distribution factor(RTDF) and CO emission decrease; with the increment of biodiesel fuels-diesel oil ratio

the combustion efficiency and outlet temperature rise gradually drop

and the outlet temperature distribution factor and NOx emissions decreases first and then increases

and the radial temperature distribution factor and CO emission increase. With the increment of fuel-air ratio

the influence of biodiesel fuels changes and wears off. Different best biodiesel fuels-diesel oil ratios exist under different conditions of fuel-air ratio.
