Process problem due to Burner pipe
Some plants normally don't change their Kiln burner or auxiliaries,even after switching to alternate fuel or plant enhancement. So they face operational problems like ring formation, burning zone brick spalling, ball formation and quality fluctuations.
If you also face the same problems or want to know more about your burner, fill details in gray cell so that I can calculate your kiln burner specification according to your present plant condition. email your details to vikprocem@gmail.com. Once I calculate then we will discuss / share your problem with other expert also.

Mr. Lui & all others who mail me the details,
By mistake I typed “Change” in place of “adjust” burner or it’s auxiliary; I want to inform you that I’m not a Burner supplier. But I want to share/gain knowledge from forum.
Many plants don’t adjust their burner or auxiliary according to fuel change or other factors, so they face problems like Ring formation, ball formation, early brick failure, high free lime and other quality fluctuations. I’ll calculate and check if there is some problem with your system.
