Supercritical Boilers

B&W's supercritical and ultra-supercritical boiler designs offer the flexibility and reliability to meet the most demanding steam generation needs of our customers.

At supercritical pressures, steam turbine efficiency improves significantly compared to the typical subcritical cycle. Ultra-supercritical steam conditions provide even greater efficiency improvements.  The combination of utilizing supercritical throttle pressures along with an increase in throttle temperatures results in cost reductions in fuel usage and handling, flue gas treatment and ash disposal.  B&W's supercritical and ultra-supercritical boilers are designed to take full advantage of variable pressure turbine operation.

Specific advantages include:

  • For a given output, lower fuel consumption, and thus lower carbon emissions, than other less efficient systems
  • The load change rate capability of the system is not restricted by the turbine
  • Steam temperature at the inlet and outlet of the reheater is nearly constant over a wide load range
  • The boiler feedwater pump power is significantly reduced at lower loads
  • Short startup times
  • Higher plant efficiency over the entire load range
