How does coke and coal play into steel making?
· It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel. Prior to the 1880's, steel was produced using charcoal. By 1920, nearly 90% of US steel was produced using coke.

Boilers
Pulverized coal boilers fire finely powdered coal, typically with an average particle size of about 25 µm ( in). Coal burns in suspension, like the combustion in an oil or gasfired boiler. Coal is pulverized in some type of large mill Pulverized coal is fired out into the furnace volume using burners that look somewhat like oil
Aerodynamic Resistance of a BallTube Mill During ...
· Analysis of experimental data on aerodynamic resistance of a balltube mill is given. It is shown that this resistance has two components brought about by the pressure losses resulting from the injection of dust particles into the main flow after coal grinding and from the transport of homogeneous gas suspension flow. A dimensionless equation has been obtained for the dependence of the ...
