(54) Method for determining the location of burners in an annular combustion chamber of a gas turbine


(57) A method for determining the location of burners (6, 7) in an annular combustion chamber (1) of a gas turbine envisages:
detecting flow rates (QPi, QPXi) of a plurality of burners (6, 7);
calculating an average flow rate (QPM, QPXM) of the detected flow rates (QPi, QPXi);
calculating a deviation (ΔQPi, ΔQPXi) of each detected flow rate (QPi, QPXi) from the average of the flow rates (QPM, QPXM); and
associating at least one of a plurality of seats (2) of the annular combustion chamber (1), that arranged along a circular path, to at least one burner (6, 7) on the basis of the calculated deviations (ΔQPi, ΔQPXi).
