CASE STUDY OF SUPERCRITICAL BOILER TECHNOLOGY

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.

First U.S. Ultrasupercritical Power Plant in Operation

materials selected for the high-pressure turbine section need reconsideration. The supercritical plant needs 'once-through' boiler, where as 'drum' type boiler is required by sub-critical power plant. In fact, once-through boilers are better suited to frequent load variations than drum type boilers, since the
