Doble extensión de pared

摘要

The reactor has tubed walls (2) comprising membranes which are cooled by a coolant surrounding a furnace (10). The walls comprise tubed extensions (3) through which the coolant passes in a single pass forced circulation. The coolant circulating in the tubes of the walls and the extension panels permit to balance the heat flow rate received from a fluidized bed circulating in a furnace (10). The extensions are arranged in pairs and are disposed perpendicular or parallel to a wall (11) or constitute furnace partition walls.
