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 in, steps and/or process:
“Now Morn her rosy steps in th’ eastern clime
Advancing, sowed the earth with orient pearl.”
—John Milton (1608–1674)
“What had really caused the women’s movement was the additional years of human life. At the turn of the century women’s life expectancy was forty-six; now it was nearly eighty. Our groping sense that we couldn’t live all those years in terms of motherhood alone was “the problem that had no name.” Realizing that it was not some freakish personal fault but our common problem as women had enabled us to take the first steps to change our lives.”
—Betty Friedan (20th century)
“It is part of the nature of consciousness, of how the mental apparatus works, that free reason is only a very occasional function of people’s “thinking” and that much of the process is made of reactions as standardized as those of the keys on a typewriter.”
—John Dos Passos (1896–1970)
