Super critical boiler - SlideShare

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.

The History of Steam Generation - Energiteknik | KTH

The steam was produced at atmospheric pressure. The boiler was made from copper, using rivets and bent metal sheets (Figure 4). In 1800, iron replaced copper in order to make the boiler last for increased pressures. Later the cylindrical design was replaced by the wagon-type design for increased capacities.

Difference Between Low- and High-Pressure Boilers | Hunker

High-Pressure Boiler Definition. High-pressure boilers will heat steam above 15 psi and water at pressures that exceed 160 psig. Temperatures in high-pressure boilers will exceed 250 degrees F. Because of the elevated pressure at which these boilers operate, they need to be monitored to ensure safety at all times.
