Offset Rotary Airlock Valves for Power Plants

UGES offset rotary airlock valves minimize particle degradation and rotor tip wear during fly ash and bottom ash handling in thermal power plants. The offset rotor geometry reduces the crushing zone between rotor and housing, extending service life when handling abrasive ash materials.

Trusted by the largest brands

Offset Rotary Airlock Valves Key Specifications

Cast iron housings with offset bore, 10-blade asymmetric rotors, and 150mm to 450mm inlets. Rated for 1.0 bar and up to 230°C with reduced-wear geometry extending service life in ash handling.

Rotor Design

Offset-mounted rotor with 10 blades and asymmetric housing clearance that reduces the grinding action between rotor tips and housing bore during ash transfer.

Housing Material

Cast iron housing with optional SS 304 lining and offset bore geometry, reducing localized wear from abrasive fly ash particles at the rotor-housing interface.

Inlet Size Range

150mm to 450mm inlet flanges with offset entry zone that reduces ash particle compression, minimizing generation of ultra-fine dust during valve operation.

Pressure Rating

Differential pressure sealing up to 1.0 bar with offset geometry maintaining reliable air sealing while reducing abrasive wear at the rotor tip contact zone.

Temperature Range

Standard operation to 120°C; high-temperature variant to 230°C for handling hot ash from economizers and air preheaters with extended rotor tip life.

Blade Configuration

10-blade offset rotor with replaceable alloy steel tips positioned to minimize nip-point contact, extending blade service intervals in abrasive ash service.

Industrial Applications

Applied in fly ash low-wear transfer, bottom ash gentle metering, and bed ash extraction. Offset design reduces rotor tip grinding for longer maintenance intervals in power plants.

Application 1

Fly Ash Low-Wear Transfer

Transfers fly ash from ESP hoppers with reduced rotor tip wear, extending maintenance intervals and reducing spare parts consumption in ash handling systems.

Application 2

Bottom Ash Gentle Metering

Meters bottom ash granules without excessive crushing, preserving ash particle size for beneficial reuse in construction materials and cement blending.

Application 3

Bed Ash Extraction

Extracts fluidized bed boiler ash with reduced particle attrition, maintaining bed material sizing for recirculation and minimizing fines carryover.
