PROBLEM TO BE SOLVED: To provide a fuel/air mixing disk for use in a fuel/air mixing combustor assembly. SOLUTION: This disk includes a first face, a second face, and at least one fuel plenum disposed between the first face and the second face. A plurality of fuel/air mixing tubes extend through the pre-mixing disk, and each mixing tube includes an outer tube wall extending axially along a tube axis and in fluid communication with at least one fuel plenum. At least a portion of the plurality of fuel/air mixing tubes further includes at least one fuel injection hole having a fuel injection hole diameter extending through the outer tube wall, and the fuel injection hole has an injection angle relative to the tube axis. Good fuel air mixing with low combustion generated NOx and low flow pressure loss translating to a high gas turbine efficiency, that is durable, and resistant to flame holding and flash back, is provided.
