How are Supercritical Boilers different from Subcritical

2020-7-20 · In supercritical units the water entering the boiler has to be of extremely high levels of purity. Supercritical boilers do not have a steam drum that separates the steam and the water.:) If the entering water quality is not good, carry over of impurities can result in turbine blade deposits.

Analysis & Optimization of Super Critical Boiler Efficiency

2018-2-15 · Supercritical units use advanced steam parameter of 240 kg/cm2. "Supercritical" is a thermodynamic expression describing the state of a substance where there is no clear difference between the fluid and the gaseous phase (i.e. it behave as a homogenous fluid). Water reaches this state at a pressure above 221 Kg/cm2.
