LIQUID FUEL BOILING NOX COMBUSTOR FOR GAS TURBINE ENGINE

PROBLEM TO BE SOLVED: To provide a gas turbine engine liquid fuel boiling NOX combustor, capable of preparing premixed gas with the required air/fuel ratio by uniformly mixing the whole of liquid fuel with air, without fail. SOLUTION: There are provided a premixing chamber 17 formed upstream of combustion regions S1, S2, a fuel injection apparatus 24 for injecting the liquid fuel MF into the premixing chamber 17, a first air inlet 18 for introducing air CA1 into the premixing chamber 17, while making the air CA1 turn about the axis center of the premixing chamber 17, and mixing the air with the liquid fuel MF, and a second air inlet 19 formed on an outer peripheral wall 17b of the premixing chamber 17 downstream of the first air inlet 18 for introducing air CA2 into the premixing chamber 17.
