Wet Bottom Furnace
A wet-bottom furnace or wet-bottom boiler is boiler that contains a wet bottom furnace. It is a kind of boiler used for pulverised fuel firing. In wet bottom boiler the bottom ash is kept in a molten state and tapped off as a liquid. Wet bottom boiler slag is a term that describes the molten condition of the ash as it is drawn from the bottom of the slag-tap or cyclone furnaces. An advantage is the fact that the end product in this process has a higher value compared to that of a dry bottom boiler. Wet bottom boilers are preferred for low volatile coals that produce a lot of ash. But it has higher investment costs and higher maintenance costs, so it is built less often.

Famous quotes containing the words wet, bottom and/or furnace:
“It was a Sunday afternoon, wet and cheerless; and a duller spectacle this earth of ours has not to show than a rainy Sunday in London.”

“I was born upon thy bank, river,
My blood flows in thy stream,
And thou meanderest forever
At the bottom of my dream.”
—Henry David Thoreau (1817–1862)
“‘Alas!’ quoth he, ‘but newly born in fiery heats I fry,
Yet none approach to warm their hearts or feel my fire but I.
My faultless breast the furnace is, the fuel wounding thorns;
Love is the fire, and sighs the smoke, the ashes shame and scorns;
The fuel justice layeth on, and mercy blows the coals;
The metal in this furnace wrought are men’s defiled souls;”
—Robert Southwell (1561?–1595)
