6 .15 Build up of noise

The sound level of a naked flame may be significantly
more than 90 dB(A) due to the high flame velocity. In
the case of fitted burners, the sound level of the single
burner which can be measured outside the furnace is
usually between 75 and 82 dB(A).
In a furnace system, the value which can be measured
depends on the capacity, excess air volume, flue gas
extraction and flue gas temperature of the single burn-
ers as well as the burner arrangement and ambient
influences.
