PURPOSE:To contrive to decrease NOx producing as least as possible and perform the stable combustion by a method wherein an air pressure in the casing of a combustor and a generator output are measured and calculated, then a fuel-air ratio at the burning part in the gas turbine combustor is controlled. CONSTITUTION:The air pressure P2 in the casing of a gas turbine combustor and a generator output Lgen are measured. A factor F(P2) is calculated based on the air pressure P2. In a calculating device 17, alpha=Lgen/F(P2) is calculated based on the air pressure P2 and the generator output Lgen. In a factor setting device 18, a bypass valve open degree setting signal CSO is set for the alpha calculated by the calculating device 17. The bypass valve open degree is controlled by the signal CSO. |
