Enter the bricks in the firing and your own coal consumption per 1,000 bricks to get the tonnage you need, what it will cost, and what changing grade does to both. Your consumption figure and your GCV figures — this tool has none of its own.
How this calculator works
Consumption is an input, not an assumption: use your own kg of coal per 1,000 bricks from a past firing.
The grade adjustment scales your consumption by the ratio of the two GCV figures you enter. Both come from your own coal reports.
No typical-consumption band and no GCV table are built in — those are industry data, and unsourced data does not ship here.
