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 steam.

Super critical boiler - LinkedIn SlideSha

Aug 21, 2014· Super critical boiler 1. SUPERCRITICAL BOILER SHIVAJI CHOUDHURY 2. What is SUPER CRITICAL The term "supercritical" refers to main steam operating conditions, being above the critical pressure of water (221. bar). Above the critical pressure there is no distinction between steam and water, i.e. above 221. bar, water is a fluid.
