Hey everyone, would really appreciate some help here.
We have a Premier Stainless 2-vessel brewhouse. Kettle is rated at 1 bar working pressure. We have a coil-type boiler that generates steam at about 10 bar, and we then send the steam through a pressure reducing station to bring it down to 1 bar for our kettle jackets. We haven't been able to achieve a proper vigorous/rolling boil. Been doing water brews this past week and at best we've seen some bubbling, but nothing that I would refer to as an acceptable boil.
The kettle RTD shows a maximum temperature of 99 degrees C, we can't seem to cross this no matter how long we run the boiler for.
Our steam guys insist that we will never be able to get to a boil with 1 bar of steam pressure, but to me that makes no sense since I've seen low pressure (15 psi) Sussman boilers achieve a really vigorous boil with similar kettles (ours is a 20 hl kettle with 2 jackets). Not to mention, there are hundreds and hundreds of similar installations where breweries boil wort with steam at 1 bar.
Our boiler is not undersized...it's sized at 850 kg/hour, whereas we only really need 350 kg/hour.
Any idea why our steam guys insist that we increase our steam pressure? The jackets are rated at 1 bar so I don't want to start sending steam at 3 bar into the jackets.
Does this have anything to do with bar(g) versus bar(a)?
FYI, the traps are working fine. And the HLT heats well...but then again, we're not trying to boil the water in the HLT.
Appreciate your help. Thanks!
