Difference Between Subcritical and Supercritical Boiler

Feb 19, 2018 · Unlike in subcritical boilers, there is no bubble formation in supercritical boilers, and liquid water immediately converts into steam. Supercritical boiler works at temperatures around 538–565°C and pressures above 3,200 psi. A supercritical boiler has a system with variable evaporation endpoint. These boilers are drum-less.

Prabir Basu, in Biomass Gasification and Pyrolysis, 2010. 7.3.3 Supercritical Water Oxidation. Supercritical water that exhibits complete miscibility with oxygen is a homogeneous reaction medium for the oxidation of organic molecules. This feature of SCW allows oxidation of harmful or toxic substances at low temperature in a process known as supercritical water oxidation (SCWO) or cold combustion.

Super critical boiler - SlideShare

With the super-critical boiler there is no stage where the water exists as two phases and requires separation, so the boiler is constructed without a drum. Typically super-critical boilers are once through boilers where water pumped in at pressure by the Boiler Feed Pump passes progressively through the heating stages of the boiler and is
