Characteristics of Coal and Coal Ash

Edy Nursanto, Adi Ilcham

Abstract


The physical character or composition of coal in the form of deposits used as trading materials are different. This is due to conditions, including peat formation, change in geological time, and methods or process of mining. The characteristics of coal, including water (moisture), volatile matter, porosity, density, grind ability, friability, weathering, size composition, Strength, and abrasiveness, determine the use. Furthermore, Ash is a residue obtained from the mineral matter due to changes in coal. The chemical composition is different with less weight than the mineral matter present in the original form. Also, the change in mass recorded during this entire process is attributed to water loss from the original silicate, CO2, and oxide from carbonate and pyrite oxide, respectively. However, the main components of ash elements include Sodium, Calcium, Magnesium, Potassium, Aluminum, Silicon, Iron, and Sulfur.
