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.

“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.”

““The room’s very hot, with all this crowd,” the Professor said to Sylvie. “I wonder why they don’t put some lumps of ice in the grate? You fill it with lumps of coal in the winter, you know, and you sit round it and enjoy the warmth. How jolly it would be to fill it now with lumps of ice, and sit round it and enjoy the coolth!””
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
“not that horror was not, not that the killings did not continue,
not that I thought there was to be no more despair,
but that as if transparent all disclosed
an otherness that was blessèd, that was bliss.
I saw Paradise in the dust of the street.”
—Denise Levertov (b. 1923)
“Parents find many different ways to work their way through the assertiveness of their two-year-olds, but seeing that assertiveness as positive energy being directed toward growth as a competent individual may open up some new possibilities.”
—Fred Rogers (20th century)
“There may perhaps be a new generation of doctors horrified by lacerations, infections, women who have douched with kitchen cleanser. What an irony it would be if fanatics continued to kill and yet it was the apathy and silence of the medical profession that most wounded the ability to provide what is, after all, a medical procedure.”
—Anna Quindlen (b. 1952)
