Hi
1. you may check the humming frequency at the problem (in the range 20 - 30 % IGV) because the frequency indicates the source of the problem.

2. does the problem occur in the summer like the winter or not?

3. if you working with ARGUS system for combustion dynamics monitoring send the data and trends of the problem (with ambient temp. and relative humidity and load)
