We are considering installing an 02 trim system on our 3 500 hp CB firetube boilers. We already have Rosemount O2 monitors which will make the initial cost cheaper. Our typical 02 runs from 7.5% at low fire down to 4% at high fire. We produce about 550 klbs of 90 psi steam a day.
How reliable are these systems, are they worth it?
