re Impact of ALKALY, SULPHURE and CHLORINE in Kiln operation and clinker quality ?

Hello Sir,

Yes our Rawmeal chloride has increases from 0.22 to 0.28 %, but we r maintaining this with 45 % bypass rate, our bypass system is designed for 50 %, and 0.3 Cl %, I not observed any disturbance in kiln operation , but only my clinker lime has gone down to 65.5 %, our target is 66 %.

ThankU

re Impact of ALKALY, SULPHURE and CHLORINE in Kiln operation and clinker quality ?

Hello Ahmed,

Looks like you have the situation under control.

The slight drop in clinker CaO content simply means that that the loss-free bypass dust is higher in CaO than clinker. This is because bypass dust is rich in calcined meal dust, which is high in LSF. Also, the clinker LSF is reduced by the adsorption of coal ash further down the kiln.

Regards,

Ted.
