coal types, some with high volatility properties prone to self-combustion. Coal is fed into the mills through carbon steel standpipes with an inside diameter of 600mm 24 and varying lengths and geometries ProbleM The power plant was having flow problems associated with their coal handling system standpipes feeding the coal mills.
In the jargon of the coal business, this procedure is called the ultimate analysis of coal. Carbon and hydrogen are the principal combustible elements in coal. On a weight basis, carbon is the predominant one. It constitutes about 60 to about 95 of the total. For most coals of 90 or less carbon, hydrogen content is generally in
