Abstract

Disclosed is a unique fuel and air premixing system for a gas turbine catalytic combustion system. The mixer utilizes a multi-channel counter-rotating swirler with aerodynamically shaped fuel pegs located upstream of the swirler. The premixing system provides the downstream catalyst with a fuel-air mixture sufficiently uniform for proper catalyst operation and wide operating limits. Features have been incorporated in the system to make it resistant to flameholding.
