Coal Blending an overview ScienceDirect Topics

For blending of multiple coals, blending calculations are best performed using the simple tabular format shown in Table 17.1. The total ash content of the mix is calculated by dividing the total tons of ash by the total tons of coal (i.e., 2400/25 000 = 0.096 = 9.6%).

Coal Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
