Heating with Coal, is it for Me?- A Beginners Guid

2009-8-6·Adjusted for inflation according to my records going back to the 80's the average cost per ton is actually a few dollars less now. As a recent example anthracite at the breaker was the same cost from the Fall of 2007 until about mid August 2008 while other fuels rose in cost dramatically. Using bituminous coal > Get A Quote >

Pulverised coal combustion (PCC) | IEA Clean Coa

The coal is ground (pulverised) to a fine powder, so that less than 2% is +300 µm and 70-75% is below 75 µm, for a bituminous coal. The pulverised coal is blown with part of the combustion air into the boiler plant through a series of burner nozzles. Secondary and tertiary air may also be added. > Get A Quote >
