Fuels Question 3
Our plant is supplied by Polysius with inline calciner. The rated output of the plant was 3000tpd. The original system was designed based using Indian domestic coal. Presently we are operating the plant at 3900tpd and we are also using 65 per cent petcoke and 35 per cent imported coal. At this operating condition, we are facing the problem of very high generation of fine clinker during burning process, resulting in the high clinker temperature causing the problem in roller press operation. In view of above, we are interested to know the reason for the same, along with the corrective measure for the improvement in clinker granulometry.

Re: Fuels
My only suggestion would be to adjust the kiln feed chemistry to achieve the same flux content as applied with the Indian coal. The other possibility is that the problem is caused by elevated sulphate in the clinker arising from the petroleum coke.

Fuels Question 4
We operate two fine coal bin of cap. 200 tons each. Due to coal fluctuation we have provided compressed air at 2kg pressure but due to this sometimes we are having problem of fire and sintered formation in bin. We have already tried blower air but with this coal fluctuation problem. Can you suggest an alternate way to avoid this problem.
