About Super Critical Thermal Power Plants

  • They operate at temperatures and pressures above critical point of water, i.e. point at which there is no difference between water gas and liquid water. It is above temperature and pressure at which liquid and gas phases of water coexist in equilibrium.
  • Difference with conventional coal-fired power plants: water is boiled to generate steam that activates turbine to generate power. They have efficiency of about 32%.
  • Benefits of SC power plants: They require less coal per megawatt-hour, higher efficiency (above 45%), lower fuel costs per megawatt and emits lower emissions (including carbon dioxide and mercury).
