The Influence of Material Properties on Equipment

Because of the lower capacity of coal handling systems for the station capacity procurement of equipment is not as difficult as for lignite handling systems. Although the moisture content is lower than that of lignite, coal also causes flow problems by clogging chutes and hoppers during rainy seasons.

The Influence of Material Properties on Equipment

Coal is not friable unlike lignite, however, during crushing a considerable amount of fines is generated which results in lot of flow problems and dust nuisance. At times “as received” coal contains stones also. Coal received from countries other than India, may contain high volatiles which will aid spontaneous combustion similar to lignite.

Five reasons why expanding brown coal mines might be a problem

Lignite is fairly wet compared to hard coal when it is excavated, and it is often burned wet — it can be as much as 75% saturation in some varieties. This makes it inefficient to burn compared to if it was dried out – which means using more fuel to get the same amount of energy, and more mining.
