Custom Designs Desulphurization Baffle Damper / Pneumatic Isolation Damper

Product description

FQMM type pneumatic hot and cold wind isolation is an important auxiliary equipment of boiler, installed in thermal power plant boiler cold, hot air path need to shut off the isolated occasions, such as: coal mill inlet duct work reliable, easy, the product sealed tight, fundamentally solve the isolation door closed lax, closing time is too long, greatly facilitate the cutting of the equipment maintenance, change and stop service has now been widely applied in the large power plants.

Main features

1. Horizontal, vertical, inclined and vertical installation can be carried out depending on the user's site conditions.

2. Interlock design is adopted for door opening, closing and locking, which is convenient for centralized computer control. For convenience of maintenance and special needs, manual operation can also be conducted on site.

3. The equipment is heat treated as a whole, which does not deform under large temperature difference, and adopts novel sealing material, which has good sealing performance and high abrasion resistance.

4. Safe and fast operation of the operating mechanism, which can complete all the actions within 20 seconds.The thermal isolation door in the use of the process to reduce the guide rail ash phenomenon, reduce the failure rate, reduce the maintenance cost and maintenance personnel labor intensity.
