Design features. A once-through boiler for supercritical applications, usually applied to systems with a capacity of 400 MW or larger; the design features a water-cooled dry bottom furnace, superheater, reheater, economizer, and air heater components — designed for variable superheater pressure load cycling and base load operation.

Supercritical - an overview | ScienceDirect Topi

Author: Let's Crack GATE & ESE 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.

Yuhuan 1,000MW Ultra-Supercritical Pressure Boile

Ultra-supercritical pressure boilers. Supercritical operation of large thermal baseload power plants during the 1980s used steam temperatures of typically 550ºC, leading to approximately 40% thermal efficiencies. Ultra-supercritical steam conditions now use supercritical pressures up to 300bar, with 600°C steam and reheat steam temperatures.
