Low Volatile Coal an overview ScienceDirect Topics

Vertical down-shot firing is used where volatile matter of coal is low, usually 18% or below. Low volatile coal takes longer to complete combustion and does not require high turbulence as in horizontal firing. The coal and primary air is fed vertically downward from the burners near one side of the furnace roof.

Coal in the cement industry

2012-11-8  Coal fineness has a direct relationship with its reactivity. Hence in the cement plant a special significance has been given to the milling behavior of coal. It has been observed that low volatile matter in coal can be co mpensated by finer grinding. It is also desirable that coal must have a high Hardgrove Grindability Index (HGI)

re High ash coal. Hi Filippo, With low volatile matter/high ash coals you have to consider the following;-(a) KILN RINGS: High-ash coals are more likely to result in ash rings within the kiln. (b) COAL FINENESS: Low volatile matter coals need to be ground finer. The 'rule of thumb' is that the R90 um target should be half of the volatile matter content, which in your case means you would have
