~Double Drum Chain-grate Coal-fired Boiler
 
Characteristics
1. Double drum and horizontal layout, up and down assembly structure, save space.
2. Reliable and safe operation.
3. Compact structure, reasonable water circulation, fast start-up.
4. Newly furnace arch structure and insulation materials make less radiating loss, improve thermal efficiency.
5. Use advanced domestic chain grate, reliable process, save energy, reduce installation and maintain workload. Reasonable air distribution, double side air inlet for combustion system which improves the efficiency. With layered coal feeder, burning efficiency is improved, carbon is reduced, save coal about 10%.
6. Automatic control system, high mechanization degree, easy operation, secure running.
7. High dust-collecting efficiency, built-in ash removal, environmental.
8. Fast packaged for shipment, good shape.
