Knife Gate Key Specifications

Actuation

Pneumatic cylinder actuation for DCS-integrated automated coal and ash handling; electric motorized actuators for modulating control; manual for maintenance isolation.

Sealing Type

Low-leakage seals for coal dust containment; zero-leakage inflatable seals for fly ash handling to prevent fugitive dust emissions and maintain environmental compliance.

Seating Configuration

Hard seated (metal-to-metal) for bottom ash at elevated temperatures; soft seated with high-temperature elastomers for coal and fly ash at moderate temperatures.

Port Shape

Circular ports for pipeline integration in pneumatic ash conveying; square and rectangular ports for coal bunker and hopper discharge applications.

Body Material

Mild steel body with stainless steel blade for corrosion resistance in ash service; Hardox wear plates for coal handling applications with high abrasion.

Size Range

Available from 150 mm to 1200 mm, covering coal feeder isolation, ash hopper discharge, and pneumatic conveying line requirements in power plants.

Industrial Applications

Coal Bunker Discharge
Installed at coal bunker outlets to regulate coal feed to crushers and pulverizers, with dust-tight sealing to prevent coal dust accumulation and fire hazards.
Fly Ash Silo Extraction
Positioned at fly ash storage silo discharge points for controlled extraction to dry ash conveying systems or water conditioning for wet disposal.
Bottom Ash Hopper Isolation
Mounted at bottom ash hopper outlets to isolate ash clinker flow to crushers and conveyors, with hard-seated blades for handling hot, abrasive ash material.
