Pulverised Coal an overview ScienceDirect Topics

The raw coal is then fed into the pulverizer along with air heated to about 330°C (650°F) from the boiler. As the coal gets crushed by the rolling action, the hot air dries it and blows the usable fine coal powder out to be used as fuel. The powdered coal from the pulverizer is directly blown to a burner in the boiler.

How To Heat With Coal Old School Rules

Jan 06, 2012· While I prefer the heating with wood, coal does have its advantages. You don’t have to chop, split it and stack it. It is a little trickier to light, but once it’s burning, you can bank coal. You throw wood in your furnace before you hit the sack, odds are you’re waking up cold. You bank a coal furnace right, you wake up warm & toasty.
