Cause of white smoke from stack?
Yes, O2 was increased and condition (opacity - white smoke) worsened. Lowered O2 and condition got better but CO started to form (O2 is down around 3% at 100% fire with decimal CO)) Decreased nh3 injection, condition worsened. Stack temp. is around 290 F. Thanks- Knowitallnot

Cause of white smoke from stack?
125 kpph water tube boiler with scr (19% aqueous nh3) and co catalyst burning ulsd (15 ppm sulfur) getting white/brown (not blue) smoke at low loads (25% fire rate). Clears up at when firing rate is raised. Exceptionally long stack, 50% is horizontal, CO is zero, Nox is 9 ppm, nh3 is 4 ppm, O2...- Knowitallnot
