: Aside from changes or problems in your chemistry program, have any changes been made to the combustion system on the boiler? The firing characteristics of your combustion system can aggravate shrink and swell conditions from load changes.
If your burners are reacting to fast or to much (over firing) for the load change for example, it can cause a more severe ammount of swell.
