The most effective measure for achieving high power plant efficiency is selecting high steam pressure and high steam temperature. Increasing the steam pressure from 167 bar, the standard for drum boilers, to 250 bar enhances the efficiency by roughly 3% without significant increases in investment costs.
The design concept of BENSON Boilers is independent of subcritical and supercritical steam pressure.
BENSON Boilers have been built to date for pressures up to 310 bar and temperatures up to 650 °C.
