FUEL/AIR MIXING DISKS FOR DRY LOW-NOx COMBUSTORS

摘要

A fuel mixer (88) for a gas turbine combustor (110) is provided. The fuel mixer (88) has a substantially cylindrical body with a flared end (81) and a tapered end (82). The flared end (81) is adapted for receiving compressed air (101) and for channeling the compressed air (101) into the fuel mixer (88). The fuel mixer (88) has a fuel/air mixing disk (85) disposed within the body proximate the flared end (81). A disk axis of the fuel/air mixing disk (85) is substantially parallel to the axis of the fuel mixer body. The fuel/air mixing disk (85) has a plurality of holes (90) parallel to the disk axis. The fuel/air mixer (88) reduces NOX and CO emissions in a gas turbine combustor (110) by providing more evenly distributed fuel/air mixtures (103) without increasing the risk of flame holding or flashback.
