Difference Between Subcritical and Supercritical Boiler | …

19/2/2018 · The term supercritical in supercritical boilers refers to the pressures above the critical point of water that the boiler is being operated. The critical point of water is at 647 K temperature and 221 bar (22.1 MPa) pressure. Pressures below 221 bar are known as "subcritical pressure" and above 221 bar is "supercritical pressure" of water.
