PROBLEM TO BE SOLVED: To permit the immediate decision of generation of abnormality in combustion by a method wherein a means is obtained for comparing an information obtained from a means for measuring combustion condition preliminarily from the natures of a fuel and combustion air, with the information of combustion condition obtained from the nature of an exhaust gas. SOLUTION: Respective measuring instruments are arranged at places suitable for measuring the natures of air, a fuel and an exhaust gas. The measurement of an air system is carried out by a thermometer 11 at the upstream side of a compressor guide vane 5 and another thermometer 12 as well as a pressure gauge 13, which are arranged on the half way between the outlet port of the compressor 2 and a combustor 3. The measurement of a fuel series is carried out with respect to a diffusion series and a premixing fuel series respectively by thermometers 15, 17 and pressure gauges 16, 18, which are at the upstream side of flow rate regulating valves 6, 7. The measurement of the nature of the exhaust gas after recovering a power is carried out by the other thermometer 23 and an NOx meter 24. Respective above-mentioned informations are inputted into a monitoring device 1 to process them and, thereafter, are outputted as the opening degree controlling signals for respective controlling and operating terminals or the guide vane 5 of an inlet port of the compressor as well as the diffusion and premixing fuel flow rate regulating valves 6, 7.
