Wetbottom units may be fired by crushed coal, such as is fed to cyclone furnaces, or by pulverized coal. The pulverized coalfired wetbottom 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.
In plants that do not burn pulverized coal, the crushed coal may be directly fed into cyclone burners, a specific kind of combustor that can efficiently burn larger pieces of coal. In plants fueled with slurried coal, the slurry is fed directly to the pulverizers and then mixed with air and fed to the steam generator.
