Difference Between Subcritical and Supercritical Boiler .

Feb 19, 2018· Unlike in subcritical boilers, there is no bubble formation in supercritical boilers, and liquid water immediately converts into steam. Supercritical boiler works at temperatures around 538–565°C and pressures above 3,200 psi. A supercritical boiler has a system with variable evaporation endpoint. These boilers are drum-less.

Supercritical steam generator - Wikiped

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 – 22 megapascals (3,200 psi).Therefore, liquid water immediately becomes indistinguishable from steam.
