Last month we replaced our 5 year old 750,000btu/hr cast iron sectional boiler due to corrosion failure from using untreated hard city water. The new utica is the same size model, but we elected to start a boiler chemical treatment & we are having 2-3" of bouncing in the sight tube?
We have a hartford loop, skimmed several times and flushed out twice, but We are having water carryover only at full load ( which is about 95% of input capacity) The steam supply tapings are two 2" diameter tapings at 8" height before they elbow to a horizontal steam line. Would any one have a recomendation to reduce boiler water carryover? Should we increase the height of these tapings to 24" or higher to keep boiler water in boiler?
I beieve the old unit had enough scale inside to insulate and minimize carryover. The old unit stack temp was 600F and the new unit is 450F.
