Coal-Fired Boiler

 Ash Cooling & Enclosed Conveying System

Intrinsic Safety:

Eliminates thermal hazards; 24/7 continuous operation without downtime.

Compliant Emissions:

100% enclosed airtight design complies with global environmental standards.

Reduced Maintenance:

Wear-resistant components extend service life by over 50%.

Pain Points & System Flowchart

3. Strict Environmental Audits

       • Traditional open conveying causes       heavy workshop dust pollution.

2. Severe Abrasion & Corrosion

        • Hard furnace slag and sulfur waste  rapidly erode metal flow parts.

System Flowchart

1. Extreme Ash Temps (600℃–1000℃)

       • Direct discharge burns rubber belts and damages downstream machinery.

Core Equipment Features

LG Series 

Rotary Drum Cooler

• Indirect Water Cooling: 

Water jackets lower bottom ash from 1000℃ to  ≤60 safely.


• Expansion Compensation:

 Floating bearings prevent shell deformation.


• Labyrinth Seals:

Prevents cold air ingress and high-temp flue dust leakage.

NE Series

Heavy-Duty Bucket Elevator

• High-Strength Chains:

Deep-quenched NE alloy chains last 2–3x longer under severe slag abrasion.


• Anti-Jamming Design:

Reinforced buckets with speed monitoring prevent large slag blockages.

LS/GX Series 

Screw Conveyor

• Multi-Stage Shaft Seals:

Air seal + skeleton oil seal + gland packing stops fine powder invasion.


• Wear-Resistant Flights:

Hardfaced alloy edges handle high-abrasion dry ash continuously.
