The promise of coal gasification has even won, at the very least, the interest of some environmental groups that have long opposed the continued use of pulverized coal plants, even though upgrades and the adaptation of such practices as Ultra Super-critical Coal technology, which increases efficiency by roughly 10 percent, have made those plants cleaner.
The raw coal is then fed into the pulverizer along with air heated to about 330°C (650°F) from the boiler. As the coal gets crushed by the rolling action, the hot air dries it and blows the usable fine coal powder out to be used as fuel. The powdered coal from the pulverizer is directly blown to a burner in the boiler.
bowl-mill pulverizer. [ ′bōl ‚mil ′pəl·və‚riz·ər] (mechanical engineering) A type of pulverizer which directly feeds a coal-fired furnace, in which springs press pivoted stationary rolls against a rotating bowl grinding ring, crushing the coal between them. Also known as a bowl mill.
The raw coal is then fed into the pulverizer along with air heated to about 650 °F (340 °C) from the boiler. As the coal gets crushed by the rolling action, the hot air dries it and blows out the usable fine coal powder to be used as fuel. The powdered coal from the pulverizer is …

The gravimetric feeder compensates for the variation in bulk density and feeds a fixed weight of coal in response to a boiler fuel demand. This ability to accurately weigh the coal provides significant improvement over volumetric types in terms of matching the fuel delivered by the feeder to the actual process energy required on coal fired units.
Recently a coal-fired power plant in the Midwest was experiencing gear coupling failure in its coal pulverizer drives. Coupling in power plant operation "We used to use scales to dump 500-pound buckets of crushed coal from the bunker into rotating paddle feeders that delivered the coal to the pulverizer," recalled Fred Stavely, a senior plant ...
