utilities and equipment manufacturers, has completed its task of finalizing standard technical specification for Main Plant Package for a coal based thermal power project having 2x (500MW or above) sub-critical units.
Ultra Supercritical Power Plants. In the quest for higher efficiency the trend is to go for still higher operating pressures. The next generation of power plants will operate with steam Pressures in the range of 300 bar. These are the Ultra Super Critical Power plants. Ultra Supercritical Units operate at temperatures of 615 to 630 deg C.
While subcritical plants generate power by boiling water into steam, supercritical systems turn water to steam without boiling. A supercritical steam generator operates at pressures above the critical pressure (where liquid water immediately becomes steam).

Abstract. The article presents a review of developments of modern high-capacity coal-fired over-supercritical (OSC) and ultra-supercritical (USC) steam power plants and their implementation.
The difference between subcritical, supercritical, and ultra-supercritical versions of pulverized coal combustion technology has to do with the steam pressure within the boiler. In a subcritical plant, steam pressure is below 3200 pounds per square inch and temperature is below 1025 degrees Fahrenheit (550 degrees Celsius).
A supercritical steam generator is a type of boiler that operates at supercritical pressure, frequently used in the production of electric power. In contrast to a subcritical boiler in which bubbles can form, a supercritical steam generator operates at pressures above the critical pressure – 3,200 psi or 22 MPa .
