Flue Gas Duct Damper

Flue Gas Duct Damper

This damper was fabricated from a combination of 304 stainless steel and Inconel®. It is designed as a shut-off damper to control the flow of flue gas in an ammonia plant. The damper will be connected to a motor-driven control system by the linkage shown in the picture. The overall dimensions are 10′ x 6′ with a weight of 2,200 lb. It was painted with standard inorganic zinc primer and top coat per customer specifications. The damper went through visual inspection, dye-penetrant, and functional testing before being shipped to the customer. Refractory lining, utilized to withstand the high temperatures, will be added during installation.

Flue Gas Duct Damper

The picture above shows a flue gas duct damper fabricated using Inconel for certain components by the Sweco Fab division of Piping Technology & Products, Inc. Two of these dampers were shipped to Trinidad for installation above the furnaces of an ammonia plant. They have a special refractory lining to withstand the high temperatures of the flue gases. The picture at the left show the linkage of the damper to the motor-driven control system. Each unit weighs approximately 2300 lb. and the openings are approximately 12 feet by 6 feet.
