: : A new package boiler with pressure of 600 psig, and 205 MCR, operating on fuel oil, with high sulfur as of 4%.
: : It was observed that some white smoke coming out of the stack. Has any one expirenced such an event before or any one can comment, please help me?
: First thought is it sounds like a combustion air flow problem, white smoke meaning there's probably not enough combustion air. Call your local boiler professional or the manufacturer if it is still new and let them tune your burner properly. You could possibly void a warranty if you do it yourself.
: About the 205 MCR, what is the units for the 205 ? t/h, kpph ?? Where's the boiler located.
White smoke exiting a stack may indicate excessive combustion air, otherwise known as a lean fuel mixture. If there is not enough combustion air, as suggested, black smoke would be typically seen. Either way, proper tuning of the burner is required, preferrably by a qualified burner/boiler technician.
