Wet-bottom units may be fired by crushed coal, such as is fed to cyclone furnaces, or by pulverized coal. The pulverized coal-fired wet-bottom unit traps 50% or less of the ash as molten slag on the furnace walls; this slag runs down to the furnace floor and taps down into the slag tanks for removal.
High-sulfur coal commonly undergoes washing to meet environmental regulations, while low-sulfur coal is often crushed and resized without being washed. Unfortunately, the contaminants and non-coal material removed during washing must go somewhere, and are typically left in large wastewater ponds, known as “slurry” reservoirs or impoundments.
