I have a client who has installed a 200 litre water tank which they are heating by steam injection. It is a system they have put together themselves so no manufacturer control. 10 min Leq of 100+ dBa has been measured. We are looking and insulating the tank to reduce noise and are looking at partitioning to protect other areas. I am no engineer myself but am wondering if anyone knows of ways of reducing the noise at source i.e the injector process.
Thanks for any help

Why did they opt for steam injection?

Not sure Paul as I wasn't involved with the design. As far as I can make out it is for speed of heating up.
Can you suggest alternatives?

Steve, try introducing compressed air in with the steam. Back in my younger days I worked in a small R&D food lab where we used to heat water via steam injection. Very noisy if one forgot to open the air valve!
Can't say I fully understand the physics of it tho'

The compressed air will stop the bubbles collapsing completely, thus reducing the noise.

We have had a word with the injector supplier and they can come up with a suitable adaption and agree with your suggestion
