Supercritical steam generator - Wikipedia

2019-10-24 · 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 – 3,200 psi or 22 MPa.Therefore, liquid water immediately becomes steam.
