Hot air isolation door
1、Brief introduction
Rectangular cold and hot air isolation doors are devices used in systems for conveying fly ash and powdered dry materials to cut off the conveyed material. They can be installed at the bottom of ash hoppers such as economizers, air preheaters, dry dust collectors, and flues in thermal power plants, and can also be used in conjunction with electric feeders. The working temperature is allowed to reach 200 ℃. This device is lightweight, small in size, and has no fly ash leakage. Our company offers both electric and manual options for use in conveying systems.
