Natural Circulation Chain Grate Coal Steam Boiler For Chemical Industry
1. DZL series is coal/biomass fired single water-drum steam boiler with horizontal structure and full-automatic operation.
2. It adopts Water Treatment for automatic water softening, Coal Feeder for automatic fuel feeding, Traveling Chain for automatic combustion, Slag Remover for automatic deslagging.
3. In additional, DZL series boiler also equipped with Economizer for full using of the waste heat in exhaust smoke, Dust Collector for realizing exhaust dedusting, Water Level Controller for automatic water feeding/water cutting, Overpressure Protective Device for automatic decompression, Sound & Light Alarm Device for malfunction warning, etc.
Features
1. Big combustion furnace, spirally corrugated tubes, dust collector, automatic operation etc. can fully enhance the thermal efficiency and reduce the smoke temperature; also gets simple operation and environmental.
2. The independent water treatment device can improve the water quality before feeding into the boiler; lengthen the boiler service life.
3. DZL boiler has automatic fuel deeding/ combustion/ deslagging etc, so the user only need one worker for boiler operation. This will save much of and labour cost; and reduce the labour intensity as well.
4. DZL series is packed boiler. After receiving the goods, user just need to connect the valve instrument/ fans/ chimney/ dust catcher/ water/ electricity for quick operation. And this kind of boiler has simple ignition and quick steam raising, etc features.
