The U.S. Energy Information Administration publishes data on electricity generation from utility-scale and small-scale systems. Utility-scale systems include power plants that have at least 1 megawatt (MW) of electric generation capacity. Small-scale systems have less than 1 MW (1,000 kilowatts) of electric generation capacity.

The pulverized-coal—fired steam generator provides main steam of 4133 psia/1112°F (285 bar/600°C) and reheat steam of 870 psia/1112°F (60 bar/600°C). The supercritical steam …
This firing method is normally used for anthracite. Mills. In a PF boiler system, coal is pulverised to typically 70–75%, passing 75 micron and entrained in preheated primary air for conveying to the burners. In some small-scale operations indirect firingis used, this is when the pulverised coal is stored in a bin before feeding to the burners.
