Coal Dust in Energy Generation
For use in thermal power plants, coal is ground into dust using a device called a powdered coal mill. The resulting product, called powdered coal or pulverized coal, is then generally used in a fossil fuel power plant for electricity generation. Pulverised coal is a significant dust explosion hazard, as large quantities are suspended in air for transfer from the mill to the power plant. Explosions have occurred when the flow drops and flames in the burning chamber pass back along the ductwork delivering fuel.

Famous quotes containing the words coal dust, coal, dust, energy and/or generation:
“Writing is to descend like a miner to the depths of the mine with a lamp on your forehead, a light whose dubious brightness falsifies everything, whose wick is in permanent danger of explosion, whose blinking illumination in the coal dust exhausts and corrodes your eyes.”
—Blaise Cendrars (1887–1961)
“In those days, the blag slag, the waste of the coal pits, had only begun to cover the side of our hill. Not enough to mar the countryside nor blacken the beauty of our village. For the colliery had only begun to poke its skinny black fingers between the green.”
—Philip Dunne (1908–1992)
“Tell me not, in mournful numbers,
Life is but an empty dream!—
For the soul is dead that slumbers,
And things are not what they seem.
Life is real! Life is earnest!
And the grave is not its goal;
Dust thou art, to dust returnest,
Was not spoken of the soul.”
—Henry Wadsworth Longfellow (1809–1882)
“In the west, Apollo and Dionysus strive for victory. Apollo makes the boundary lines that are civilization but that lead to convention, constraint, oppression. Dionysus is energy unbound, mad, callous, destructive, wasteful. Apollo is law, history, tradition, the dignity and safety of custom and form. Dionysus is the new, exhilarating but rude, sweeping all away to begin again. Apollo is a tyrant, Dionysus is a vandal.”
—Camille Paglia (b. 1947)
“Today’s comedian has a cross to bear that he built himself. A comedian of the older generation did an “act” and he told the audience, “This is my act.” Today’s comic is not doing an act. The audience assumes he’s telling the truth. What is truth today may be a damn lie next week.”
—Lenny Bruce (1925–1966)
