Steps in The Process
- Both boiler types have a solid base with an orifice that can be opened to permit the molten ash that has collected at the base to flow into the ash hopper below.
- The ash hopper in wet-bottom furnaces contains quenching water.
- When the molten slag comes in contact with the quenching water, it fractures instantly, crystallizes, and forms pellets.
- The resulting boiler slag, often referred to as “black beauty,” is a coarse, hard, black, angular, glassy material.
- At intervals, high-pressure water jets wash the boiler slag from the hopper pit into a sluiceway which is then conveys it to a collection basin for dewatering, possible crushing or screening, and either disposal or reuse.

Famous quotes containing the words steps and/or process:
“Painting seems to be to the eye what dancing is to the limbs. When that has educated the frame to self-possession, to nimbleness, to grace, the steps of the dancing-master are better forgotten; so painting teaches me the splendor of color and the expression of form, and as I see many pictures and higher genius in the art, I see the boundless opulence of the pencil, the indifferency in which the artist stands free to choose out of the possible forms.”
—Ralph Waldo Emerson (1803–1882)
“Science and art are only too often a superior kind of dope, possessing this advantage over booze and morphia: that they can be indulged in with a good conscience and with the conviction that, in the process of indulging, one is leading the “higher life.””
—Aldous Huxley (1894–1963)
