Supercritical coal plant - Energy Education
Supercritical coal plants are a type of coal-fired power plant used in more modern designs. They differ from traditional coal power plants because the water running through it works as a supercritical fluid, meaning it is neither a liquid or a gas.

Small-Scale Flexible Advanced Ultra-Supercritical Coal
An 84MWth coal- -fired combinedheat--and-power plant was recently built at the University of Alaska Fairbanks for $248M, which equates to ~$8000/kW. In this area, the relative annual fuel costs for the plant were about $5M for coal and $20M for NG.

SUPERCRITICAL COAL FIRED POWER PLANT
As name suggests, coal-fired supercritical power plants operate at very high temperature and pressure (580 degree centigrade temp. with a pressure of 23 MPa) resulting much higher heat efficiencies (46%), as compare to sub-critical coalfired plants which operates at 455 degree centigrade temp., and - efficiency of within 40%.

Lean and clean: why modern coal-fired power plants are
Jun 21, 2016 · The situation had barely improved three years later when an IEA study into coal-fired power plant design in China found that the global average efficiency of coal-fired power plants in operation was around 33%, significantly lower than the 45% possible using modern, ultra-supercritical technology. Progress is undoubtedly being made, however.

Pulverized coal-fired boiler - Wikipedia
Pulverized coal power plants are broken down into three categories; subcritical pulverized coal (SubCPC) plants, supercritical pulverized coal (SCPC) plants, and ultra-supercritical pulverized coal (USCPC) plants. The primary difference between the three types of pulverized coal boilers are the operating temperatures and pressures.
