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. 3.
