Abstract
Transition castings are disclosed which comprise a steam tube and a water tube, which are joined together by membranes. A heat transfer fin extends from the membrane and abuts the water tube. The steam tube bends such that an upper end is on one side of the water tube, and a lower end is on an opposite side of the water tube. The transition castings are used in a transition section of a boiler in which the furnace is divided into a lower furnace and an upper furnace. The lower furnace uses water-cooled membrane walls, while the upper furnace uses steam-cooled membrane walls that act as superheating surfaces. The transition casting joins the lower furnace and the upper furnace together.
