Boiler design for ultra-supercritical coal power plants

In a conventional boiler with a steam drum, feedwater is heated into a mixture of steam and water in the furnace water-cooled wall. The drum stores the saturated steam generated and acts as a phase-separator for the steam-water mixture. The steam is transported to the superheater, while the water is returned to the water-cooled wall.
