DZL coal fired steam boilers, are horizontal three-pass water & fire tube boilers with a chain grate stoker structure. Threaded pyrotechnic tubes are arranged in the drum to form a convection heating surface,while the drum and the water walls on both sides from a radiation heating surface in the furnace.
1.Characeteristics Of DZL Coal Fired Steam Boiler
- Durable and Long life time.
- Enough steam output, less heat dissipation, high thermal efficiency, lowest consumption.
- High efficiency dust collector, more Eco-friendly.
- Full automatic control, Protection devices for overheating, over-pressure, lacking water, leak detection, flame-out
- Automatic fuel feeding, automatic water feeding, automatic ash remove so on.
