In order to study the effect of inlet air distribution in swirling combustion chamber, we present a new type of slotted swirler which suits to main combustion chamber. Numerical simulation are employed for the research on the combustion performance in three swirl burners with different structures (normal swirler, 4 slits swirler, 8 slits swirler), analyze the flow field characteristics and temperature field characteristics in slotted swirler chamber. The slotted swirler combustor has certain superiority in terms of combustion performance. The results showed that the slotted swirler combustor has some advantages in lower flow resistance, better combustion stability and higher combustion efficiency. Introduction |
