Coal Density an overview | ScienceDirect Topics


The free-swelling index (FSI) or crucible swelling number (CSN). This is a measure of the increase in volume of the coal when it is heated in a small crucible in the absence of air. This test is also used to characterize coals for combustion, especially where the coal is burned in beds of coarse-crushed material in stoker-based systems.


The crushed coal is either fed to coal bunkers of the boilers or discharged on to conveyors for storage in coal stockyard through conveyors and transfer points. Crushed coal is sent to stockyard when coal bunkers are full. Stacking/reclaiming of coal is done by bucket wheel type stacker-cumreclaimer moving on rails. The stacker-cum-reclaimer

Assume you are using dry gravel with a swell percentage of 15% and a shrink percentage of -7% Plug those values in to the calculator and it will tell you that the compaction factor = 1.273. Multiply the 1185 cubic yards by 1.273 1185 * 1.273 = 1508. To complete this job you will need 1508 cubic yards of this gravel in loose state volume.
