Abstract: PROBLEM TO BE SOLVED: To provide a measure taken to stabilize a flame in a burner to a maximum limit. SOLUTION: The burner for a heat generator is provided. The burner comprises at least one premixing zone at an upstream side of a combustion chamber 30. The zone has a means 100 for generating a vortex flow of combustion air. At least one fuel injector 116 is provided in the zone. A sensor 400 is provided at a downstream side of the injector 116. The sensor 400 detects back fires 81, 80 of a premixing flame 50 in the burner from the chamber 30 to start fuel controlling.

Abstract: PROBLEM TO BE SOLVED: To realize a quick and accurate measurement of temperature without giving a bad effect to the flame, by disposing optical measuring sensors immediately on the upstream side from a flame front in the premixing region of a burner while directing in parallel and/or coaxially with a fuel flow being introduced into a gas turbine burner. SOLUTION: A burner 1 and a fuel line 4 coupled therewith are provided with a measuring sensor 7. The measuring sensor 7 is fixed to a premixing region 3 substantially in parallel with the direction 5 of a fuel flow or disposed in the center of the fuel line 4. The measuring sensors 7 are directed toward all flame front 8. Numerical aperture of the measuring sensors 7 is set such that a conical observation capacity including a flame front region essential for combustion process is opened and the flame front 8 is observed from the upstream side. Even if the flame 8 vibrates in a plane perpendicular to the flow direction 5 due to thermoacoustic vibration of a burner, it has substantially no effect on the optical temperature measurement.

Abstract: In a temperature measurement process for determining the adiabatic temperature of a flame, in particular in a gas turbine combustion chamber, the chimioluminescent radiation emitted by the OH and/or CH radicals in the flame is sensed by a spectrograph by means of an optical fibre. The spectrally resolved raw signal from the chimioluminescent radiation is then corrected and compared with a plurality of theoretically determined emission spectra until a theoretical emission spectrum matches the chimioluminescent spectrum. The Boltzmann temperature which corresponds to said matching emission spectrum is then associated to the chimioluminescent spectrum and the adiabatic flame temperature is derived from the Boltzmann temperature by correlation.
