Stack Silencer Refurbishment

Our ongoing independent acoustic noise studies and surveys over an extended period have verified that noise emanating from the top of one of our major stacks (4A) was producing a dominant tone in the neighbourhood (noise actually comes from large fans at the bottom of the stack).

In discussion with our acoustic consultants our noise reduction team decided that the best option would be to modify an existing noise silencer/attenuator located midway in the stack.

The design of the silencer was subsequently assessed by the noise consultants for its suitability and any improvements that could be made to possibly eliminate the tone.

After significant planning and review the silencer was removed for assessment and refurbishment during a major shutdown in March last year.

The silencer underwent a complete overhaul and two subsequent periods of external noise testing has verified that the dominant stack tone has been completely eliminated.
