2. Supercritical steam generator - Wikipedia

   en.wikipedia.org/wiki/Supercritical_steam_generator

   A supercritical steam generator is a type of boiler that operates at supercritical pressure and temperature, frequently used in the production of electric power. In contrast to a subcritical boiler in which steam bubbles form, a supercritical steam generator operates above the critical pressure – 22 megapascals (3,200 psi ) and temperature ...

3. John W. Turk Jr. Coal Plant - Wikipedia

   en.wikipedia.org/wiki/John_W._Turk_Jr._Coal_Plant

   Named for former SWEPCO president and CEO John W. Turk Jr., the plant came online in 2012 as the first sustained "ultra"-supercritical coal plant in the United States, reaching boiler temperatures above 1,112 °F (600 °C) and pressures above 4,500 psi (310 bar). [3] The plant relies on low-sulfur coal from the Powder River Basin.

4. Pulverized coal-fired boiler - Wikipedia

   en.wikipedia.org/wiki/Pulverized_coal-fired_boiler

   The primary difference between the three types of pulverized coal boilers are the operating temperatures and pressures. Subcritical plants operate below the critical point of water (647.096 K and 22.064 MPa). Supercritical and ultra-supercritical plants operate above the critical point.

5. Thermal power station - Wikipedia

   en.wikipedia.org/wiki/Thermal_power_station

   The boiler feed water used in the steam boiler is a means of transferring heat energy from the burning fuel to the mechanical energy of the spinning steam turbine. The total feed water consists of recirculated condensate water and purified makeup water .

   Nov. 21—The replacement of mechanical systems at three schools in the district is estimated to cost about $3.96 million, engineers with ISG Inc. presented to the Albert Lea school board Monday.

7. Boiler (power generation) - Wikipedia

   en.wikipedia.org/wiki/Boiler_(power_generation)

   Supercritical steam generators are frequently used for the production of electric power. They operate at supercritical pressure. In contrast to a "subcritical boiler", a supercritical steam generator operates at such a high pressure (over 3,200 psi or 22.06 MPa) that actual boiling ceases to occur, the boiler has no liquid water - steam separation.
