Abstract (en)
The burner component for a gas turbine burner, comprises a carrier (3), a fuel nozzle (7) mounted on the carrier and a fuel distributing system (19), which is intended for supplying the fuel nozzle with fuel into the carrier and has a channel (15) and a cover strip (25) for covering the channel. The burner component is made of a ferritic material, which has heat conductivity of greater than 18 J/(Kms), specific heat capacity of greater than 510 j/(kgK) and co-efficient of thermal expansion of less than 14.8 (10->6>/K), at 400[deg] C. The cover strip and the carrier are made of same materials.
