How Supercritical Power Plant Differ from Conventional

Apr 24, 2009 · 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. Materials. Supercritical power plants use special high grade materials for the boiler tubes. The turbine blades are also of improved design and materials.
