This patent describes a method of starting gas turbine of the type having: at least one combustor including a primary combustion chamber provided with means for supplying primary fuel and primary air supply ports. A secondary combustion chamber is downstream from the primary combustion chamber and is provided with means for supplying secondary fuel into the secondary combustion chamber and secondary air supply ports, a compressor for supplying the combustor with compressed combustion air. A gas turbine is driven by a combustion gas generated in the combustor; the method comprises commencing bleeding of a part of the compressed air to reduce the rate of supply of the combustion air to the combustor after the combustion of the primary fuel is commenced; and then commencing the combustion of the secondary fuel.
