How Supercritical Power Plant Differ from

The evaporation end point can occur in various levels of the furnace depending on the boiler load. The percentage of Superheat in supercritical units is higher than subcritical units. Because of this the furnace tubes act more as superheaters than waterwalls. This necessitates the use of higher grade of materials like alloy steels in the furnace.
