Butterfly Type Main Stack Damper
The frame shall transfer all dead loads, induced wind shear load and wind moment load as calculated at the proposed location, consequentially the damper shell thickness shall be the same as the thickest stack shell in which it is located. The damper blades shall operate freely with any of the imposed calculated loads transmitted through the damper frame.
The HRSG Stack Closure Damper is provided to slow HRSG component temperature decay rate by limiting convective heat loss through the HRSG and stack following gas turbine shutdowns.
The Main Stack Damper adopts the butterfly type to open type structure, the structure is simple and reliable, compared with the louver type structure, the sealing perimeter is reduced obviously, and the sealing effect is better.
Two core technologies:
Efficient waste heat recovery technology, preheating cold water, high thermal efficiency and saving fuel costs!
Low nitrogen boiler design + low nitrogen burner, low nitrogen emission!
It has been focusing on boiler production for 30 years, covering an area of 36,000 square meters. There are more than 200 employees, including 6 engineers, 18 engineers and 35 engineering technicians. The sales manager is online 24 hours a day, and the after-sales service can be reached within an hour! Welcome to visit the factory and test the machine on site.
