re kiln upset


the actual problem is as follows:

1-kiln run with more than design feed

2-the oil ratio 33% main burner and calciner is 67% we tried to adjusted to 40%main and calciner is 60 but CO appeared in kiln inlet and ID fan draft with 93%?

3-for maintain the CO the TAD closed to 45% until increasing O2 in kiln inlet and negativity closed to -0.15 mbar

re kiln upset

Hello Elwathig,

It appears that you may be close to the maximum feed rate for your ID fan capacity.  How far above design feed rate are you running?
