Blow-Through Rotary Airlock Valves for Power Plants

UGES blow-through rotary airlock valves provide compact, in-line fly ash and bottom ash conveying for thermal power stations. The closed-pocket rotor design allows pressurized conveying air to purge each pocket directly, enabling efficient dense-phase ash transport without additional feeding equipment.

Trusted by largest brands

Blow-Through Rotary Airlock Valves Key Specifications

Cast iron housings with SS 304 lining, 10-blade closed-pocket rotors, and 150mm to 450mm inlets. Rated for 1.0 bar conveying pressure and up to 230°C for in-line power plant ash transport.

Rotor Design

Closed-pocket blow-through rotor with 10 blades and integrated air channels for direct ash purging, maximizing ash pickup and minimizing residual buildup in pockets.

Housing Material

Cast iron housing with SS 304 internal lining and blow-through air ports, providing corrosion and abrasion resistance for sulfur-laden fly ash conveying.

Inlet Size Range

150mm to 450mm inlet flanges with precision-machined blow-through ports sized to match the conveying air volume required for power plant ash handling.

Pressure Rating

Conveying air pressure up to 1.0 bar with optimized pocket geometry that ensures complete ash evacuation during each blow-through cycle.

Temperature Range

Standard operation to 120°C; high-temperature variant to 230°C for direct discharge from economizer hoppers and hot-side ESP compartments.

Blade Configuration

10-blade closed-pocket rotor with replaceable alloy steel tips and radiused pocket floors to prevent ash packing and ensure clean blow-through.

Industrial Applications

Used in ESP fly ash dense-phase conveying, economizer ash handling, and coal dust injection. Blow-through design reduces equipment count by combining airlock and feeder functions.

Application 1

ESP Fly Ash Dense-Phase Conveying

Directly conveys collected fly ash from ESP hoppers into dense-phase transport lines using blow-through air, reducing equipment count under each hopper row.

Application 2

Economizer Ash Handling

Feeds hot economizer ash directly into pressurized conveying pipelines, combining airlock isolation and material injection in a single valve for compact layout.

Application 3

Coal Dust Injection

Injects pulverized coal dust from mill outlets directly into pneumatic transport lines feeding burner systems, providing precise metering with blow-through efficiency.
