<p>Disclosed is a unique fuel and air premixing system (1300) for a gas turbine catalytic combustion system. The mixer (1300) utilizes a multi-channel counter-rotating swirler (312) with aerodynamically shaped fuel pegs (700) located upstream of the swirler (312). The premixing system (1300) provides the downstream catalyst (1306) with a fuel-air mixture sufficiently uniform for proper catalyst (1306) operation and wide operating limits. Features (L1, L2) have been incorporated in the system (1300) to make it resistant to flameholding.</p> |
