摘要：In this paper we focus on the request of low emission combustion in gas turbine and propose an improved solution of fuel injector with air-blast atomizer unit. Researches on the characteristics of the air-blast fuel spray injected into the cross flow are based on experimental study by Malvern instruments. Results reveal that specific parameters such as main air cross flow velocity and assisted atomization air pressure drop determine the performances of air-blast atomizer unit. We use these units to improve the structure of fuel injectors in gas turbine combustor. Contrast tests show Sauter mean diameter of optimized solution decreases obviously while uniformity of fuel spray becomes better. It will provide references for improving the performance of low emission combustor in gas turbine.
