The results show that the formation of the unique flowfield structure is closely related to the interaction among combustor configuration, the primary jet and the control jet; and that certain rules should be followed in order to obtain the optimum condition for flame stabilization. The distributions of temperature and concentrations of NO, O2, CO and CO2 inside the combustor were experimentally measured. The effects of structural and operational parameters on combustion and NO formation were studied. It was found that reduction of primary air, suitable use of control jet and reasonable uptilt angle of the primary jet all contributed to the reduction of NOx at the combustor exit. A new hypothesis, that reasonable separation of oxygen and fuel within the fuel-rich zone is beneficial to further reduction of NOx emission, is given. The study showed that good compatibility existed between the capability of flame stabilization and low NOx emission for this type of combustor.
