Abstract
A fuel mixer for a gas turbine combustor is provided. The fuel mixer has a substantially cylindrical body with a flared end and a tapered end. The flared end is adapted for receiving compressed air and for channeling the compressed air into the fuel mixer. The fuel mixer has a fuel/air mixing disk disposed within the body proximate the flared end. A disk axis of the fuel/air mixing disk is substantially parallel to the axis of the fuel mixer body. The fuel/air mixing disk has a plurality of holes parallel to the disk axis. The fuel/air mixer reduces NO.sub.x and CO emissions in a gas turbine combustor by providing more evenly distributed fuel/air mixtures without increasing the risk of flame holding or flashback.
