Popular DZL Chain Grate Coal Boiler
DZL series chain grate coal-fired boiler, it is a horizontal three-pass water-fire tube design with automatic chain grate combustion. With features of offers stable operation, efficient fuel combustion, and strong adaptability to different coal types.
DZL Boiler Structure Features
1. Horizontal three-pass structure
The boiler adopts a compact horizontal water-tube and fire-tube structure, providing a large heating surface and efficient heat transfer while maintaining stable and reliable operation.
2. Spiral corrugated tubes
The water tubes and fire tubes use spirally corrugated tubes, which increase the heat-transfer area, enhance gas turbulence, and improve overall heat-transfer efficiency. This helps reduce heat loss and improve boiler thermal efficiency.
3. Special furnace arch design
The furnace adopts an upside-down “α”-shaped flue gas flow structure, which effectively extends the residence time of hot flue gas in the furnace. This promotes more complete combustion of coal and biomass fuels, improving fuel utilization and reducing unburned carbon.
4. Efficient steam-water separation
A dedicated steam-water separation device is installed inside the boiler to effectively separate water droplets from saturated steam. It ensures a high-quality, dry and stable steam output, making the boiler suitable for industrial processes with demanding steam quality requirements.
DZL Boiler Advantages
1. Easy Installation: Fast-assembly leave from factory, easy to transport and install at site.
2. Full Combustion: Reasonable design of furnace structure with best suitable grate device, fuel fired fully.
3. High Efficiency Grate: Chain grate, easy operation, have lots of advantages compared to traditional grate.
4. High Security: Equip with water lack protection and over pressure protection devices, security and reliable.
5. Long Life and Durable: Advanced production processes, strict quality inspection, boiler life span above 20 years.
6. Environmental Protection and Low Noise: Low noise fans, dust remove device, meet local emission requirements.
