Directorate of Steam Boilers

Super Critical Boiler

Super Critical Boilers are the boilers which operate at steam pressure higher than critical point. Critical point is 22.064 Mpa, 373.946 deg cen. at this point latent heat of evaporation is zero & there is no difference in density of steam & water.

Supercritical boilers are being installed in the state of Maharastra & this supercritical technology is future for power generation in the world.

  • Efficiency at 25.4 MPA, 5710C is 42.26%
  • Operational Flexibility Once through technology ideal for sliding pressure operation & much more load following capabilities
  • Better heat rate as low as 2035 kcals/kwh
