As these coals are very easy to mill, there are savings from reduced mill power consumption for a given coal throughput. Low volatile coal may also allow the mill capacity to be increased, thus allowing the steelworks to increase injection rates without further capital expenditure on …
Bituminous Coal Characteristics and Applications
Bituminous coal can be categorized further by the level of volatile matter; it contains high-volatile A, B, and C, medium-volatile, and low-volatile. Volatile matter includes any material that is liberated from the coal at high temperatures. In the case of coal, the volatile matter may include sulfur and hydrocarbons.
Cement Plants: Coal
London coal gas production began in 1813 and by 1842 was producing 300,000 tons of coke a year, so coke was also readily available, and, being essentially a waste product, was cheaper than coal. Early cement plants used coal for drying slurry and for power generation, and coke for kiln burning.
Coal in the cement industry
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 ash coal - Page 1 of 1 - International Cement …
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 ...
Pet coke in cement clinker - LinkedIn SlideShare
* In comparison to coal, pet-coke is categoriesed as a material with low volatile, very low ash content, high fixed carbon content and high sulphur content. * Depending on the type of crude oil, the sulphut content may vary between 0.7% to 8%. * However, mostly the sulphur content is high, typically in the range of 2 to 8%. 5.

Medium-volatile bituminous coals are the transition from high volatile to low volatile coal and as such have the characteristics of both. Many have a granular structure, are soft, and crumble easily. Some are homogeneous with very faint indications of grains or layers. Others are more distinct laminar structure, are hard, and stand handling well.
