SUPERCRITICAL STEAM GENERATOR TECHNOLOGY

2013-12-18·steam temperatures because the re-heater pressures are much lower, so the tubes experience lower stress levels. TYPE OF SUPERCRITICAL STEAM GENERATORS & MANUFACTURERS Around the same time, two once-through boiler technologies viz., spiral type furnace and vertical type furnace with high mass flux were developed by Benson and Sulzer respectively.

A Generalized Dynamic Water Side Model for a Once

Abstract. This paper presents a dynamic model of a supercritical circulating fluidized bed (CFB) Benson type once-through utility (OTU) boiler. The water-steam cycle of the boiler is modelled using generalized model blocks able to handle thermodynamics of water, saturated water-steam mixture, and superheated steam under sub- and supercritical pressures.
