PROBLEM TO BE SOLVED: To provide a fuel/air premixer used for a burner in a combustion system of a gas turbine.SOLUTION: The fuel/air premixer includes air inlets (1, 6), fixed nozzle geometry (4), and a circular mixing passage (3). The fuel/air mixer mixes fuel and air in the circular mixing passage and injects the mixture into a combustor reaction zone (5). A plurality of fuel supply sources (21, 22) are connected to the fixed nozzle geometry. The respective fuel supply sources can cooperate with the fixed nozzle geometry so as to achieve a plurality of fuel flow changes including changes in a fuel type, fuel blend, volume flow rate and a pressure ratio. |
