The use of alternative fuels is likely to raise production prices. Cement industries could also shift to imported coal. However, it is approximately 15 per cent more expensive than petcoke and would require a price hike of about Rs 10 per bag to sustain production. This burden would likely be shifted to the end user.

Coal and petcoke are pulverized to about raw meal fineness in grinding plants using equipment similar to the rawmaterial grinding plants. The fineness of the pulverized fuel is important: too fine fuel can cause excessively high flame temperatures; too coarse fuel can cause poor combustion. Low volatility solid fuel will need finer grinding.
