BEHAVIOUR OF LOW RANK HIGH MOISTURE COAL IN LARGE

The size distribution shows a mean size of 10mm and low proportions of ultra-fine material, which makes the crushed coal suitable for stockpile drainage as there should be ample clearance between particles. Dry conditions allowed the piles to drain free moisture at a loss rate of between 0.7 and 1.7% per day.

Coal Properties and its influence on Boiler Pankaj Ekbote

• Moisture and Hydrogen in coal also play a role in the size of ESP, • Precipitator efficiency increases with increase in fly ash particle size which is affected by PF size, the fusibility characteristics of the coal ash and combustion conditions. • Coarser PF tends to yield a larger average fly ash particle size (or mass median diameter).

Coal Density an overview ScienceDirect Topics

A distinction must be made among bulk densities, which are determined by the average particle (or lump) size, size distribution, and packing density of the coal, because these affect handling, transportation, and storage. The true density (ASTM D167) is usually determined by displacement of a fluid. Because of the porous nature of coal and physicochemical interactions, the observed density
