Engineering noise control solution for burner noise nuisance

A low frequency burner drone from an industrial boiler was causing noise nuisance complaints. The usual noise reduction solution for boiler noise is a large industrial silencer. In this case, to provide a 20 dB reduction in the noise drone, a silencer manufacturer quoted £10,000 - £14,000 depending on the allowable pressure drop. The company decided that this was too expensive and sought our help. Our engineering noise control solution produced a 22 dB reduction in the boiler drone with no pressure drop. The cost was £2000. So, the company saved £8,000 - £12,000 by selecting our engineering noise control solution instead of a silencer.

More details and examples of engineering noise control solutions are shown on the Industrial Noise Control - Noise at Work and Industrial Noise Control - Noise Nuisance pages of this web site.

General comments about burner noise reduction

Low frequency combustion noise from various types of burner, boiler, dryer, furnace, etc. are a common cause of noise nuisance, and often requires a large noise reduction. The drone frequency is usually so low that normal noise control equipment like an industrial silencer provide little noise reduction (unless a very large, complex silencer is used, which is extremely expensive as shown by the above example). In contrast, engineering noise control solutions provide a high noise reduction at low cost. Here are a few examples of the large reduction in burner noise achieved by an engineering noise control solution:-

A noise reduction of 11 dBA was achieved on a drier using a very low cost engineering noise control solution.

An engineering noise control solution eliminated a low frequency (37 Hz) burner noise drone, providing a 22 dB noise reduction.

A 15 dB reduction in a low frequency (110 Hz) boiler noise drone was produced by a low cost engineering noise control solution.

An engineering noise control solution achieved 10 dB noise reduction in a low frequency (117 Hz) boiler noise drone.
