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.Get Price
2.1 Sub-critical Boilers Water when heated at sub-critical pressure (less than 22.1 MPa) increases in temperature until it starts to boil. While the water is boiling it exists as two phases, liquid and as that have different mass densities, and remains at a constantg temperature known as the saturation temperature for the given pressure.
