Supercritical water exists at temperatures above 374 °C and pressures above 220 atmospheres. Diagram of a supercritical water-cooled nuclear reactor. A supercritical steam generator is a type of boiler that operates at supercritical pressure and temperature, frequently used in the production of electric power.
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.
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.
There are 4 main types of coal-fired power station in increasing order of efficiency are: subcritical, supercritical, ultra-supercritical and cogeneration (also called combined heat and power or CHP). [31]
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.
The SCWR operates at supercritical pressure. The reactor outlet coolant is supercritical water.Light water is used as a neutron moderator and coolant. Above the critical point, steam and liquid become the same density and are indistinguishable, eliminating the need for pressurizers and steam generators (), or jet/recirculation pumps, steam separators and dryers ().
The power station consists of two 1,000MW ultra-supercritical coal-fired units, each with a once-through boiler and a 3000rpm steam turbine operating at 603°C and 270 bar. The units feature water-cooled stator, hydrogen-cooled rotor generators, a 160m-high chimney with 9.1m internal diameter, and on-site ash storage facilities.
Emerging technologies such as supercritical and ultra-supercritical thermal power stations operate at higher temperatures and pressures for increased efficiency and reduced emissions. Cogeneration or CHP (Combined Heat and Power) technology, the simultaneous production of electricity and useful heat from the same fuel source, improves the ...
