METHOD FOR CONTROLLING A SEQUENTIAL COMBUSTOR OF A GAS TURBINE ENGINE AND GAS TURBINE POWER PLANT

A method for controlling a sequential combustor (10) of a gas turbine engine (2) includes the method comprising supplying the first combustor stage (12) of the sequential combustor (10) with a first air/fuel mixture (M1) and supplying a second combustor stage (13) of the sequential combustor (10) with a second air/fuel mixture (M2). The first air/fuel mixture (M1) contains ammonia and is stoichiometric or sub-stoichiometric.
