Re: CO content
Dear Kotiyal,
my kiln running with coal residue from 2.5 to 4% for a long time and we have been never changed with coal residue. I have understood problem delay burning but i don't understood why we have to try to reduced CO content and then kiln burning zone cooling down also. This phenomenon appearing around 1 month, not have before.
Please explaine clearly to me.
thanks in advance.

Re: CO content
Dear minh,
Let me know your burner make, setting of primary air current values.coal conveying blower air volume, and the burner channel areas. if some of the parameters of radial and axial air or the conveying blower volume is disturbed too this can cause problems.
