Abstract
The invention discloses a partition wall for an ultra-supercritical boiler economizer outlet flue. In a unit installation process, a large potential safety hazard exists in an original partition wall operation due to effects of construction environment and construction ability on a construction unit and quality uncertainty of a partition wall protection board in slotting production and welding process. The partition wall comprises an economizer inlet header (2) with a pipe joint (1), and a tail flue inlet header (3), wherein the tail flue inlet header is connected with a clamping plate (4); the clamping plate is connected with a bent hanger plate (6) through a bolt (5); the bent hanger plate is connected with a reinforced rib plate (7), and lateral sealing plates (8) are arranged at two ends of the bent hanger plate and the reinforced rib plate; the bent hanger plate is inserted into a bent insertion plate, and the other end of the bent insertion plate is connected with the economizer inlet header. The partition wall is used for the ultra-supercritical boiler economizer outlet flue.
