We have an installation that has swaged tubes installed in the lower furnace. Recently we have experienced some failures of these tubes. The boiler rep is pointing towards possible water treatment issues, however, we have had no failures away from the swaged tubes. The tubes were not stress...
I have long believed that elevated copper levels in feedwater is bad. What I am ignorant on is the damages that may result in boilers from 600 psig to 1500 psig. Any information on this subject would be appreciated.

Is there any way to quantify a leak based on lost pressure. A SCAH being pressure tested with air to 25 psig. Over a two hour period the pressure decays slowly to 5 psig. Is there criteria for how long pressure must be held to determine if there are no or no significant leaks leaks? I was...
Does anyone know how much subcooling is possible (typical) in a sweetwater condenser? Steam at saturations (534 Deg F) with feedwater entering in at 350 Deg F. Our design shows very little however we have about 150 Deg.F subcooling right now. Of course this may indicate a leak, however, the...
