Abstract
In a temperature-measuring device, in particular for measuring the flame temperature in a gas turbine combustion chamber, a number of optical measuring sensors (7) are arranged directly upstream of a flame front (8) in a premixing zone (3) of a burner (1). Each optical measuring sensor (7) is aligned essentially parallel to and/or coaxial with a fuel flow (5) directed into the gas turbine combustion chamber.
Claims6
Apparatus for measuring the temperature of the flame front in a gas turbine combustion chamber, the apparatus comprising a burner having a central axis, conduit means for introducing fuel and air into the burner along the central axis of the burner, a gas turbine combustion chamber having a front plate, the burner having a premixing zone between the conduit means and the front plate, the front plate having an opening aligned with the central axis of the burner, and at least one optical measuring sensor aligned with the central axis, whereby the at least one sensor is exposed to the flame front through the front plate opening.
Apparatus for measuring the temperature of a flame burning in a gas turbine combustion chamber, comprising:
- a flame tube having a front plate, the front plate having an opening, premixing means for mixing a combustible mixture in a premixing zone having an inlet and an outlet, the outlet of the premixing zone being aligned with and encompassing the front plate opening, at least one optical measuring sensor being located adjacent the premixing zone inlet, conduit means for supplying fuel and air to the inlet of the premixing zone, the conduit means and the premixing zone and the flame tube being in axial alignment, the sensor being positioned to receive heat radiation from the flame front burning in the flame tube.
