Automatic Moving Grate Coal Fired Steam Boiler DZL-Series boiler is horizontal single-drum shell boiler with water-fire tubes. It has chain grate as burning device, upper-in-and-upper-out style natural water circulation with ejection for hot water boiler of this series, the right and left side of furnace as radiant heating surface, two wings of furnace and threaded smoke tubes as convection heating surface and three-dimensional shield shell. Furnace is divided by Smoke baffle wall into combustion chamber (firebox) at front and reburning chamber at back.
1. Adopts horizontal type three pass structure and large furnace, to ensure the sufficient combustion.
2. The steam boiler adopts arched tube plate and spirally corrugated tube, change the quasi-steel body into quasi-elastic body structure, reduce stress.
3. The spirally corrugated tube strengthen the heat transfer, improve thermal efficiency. The flue gas has the foundation of disturbance, avoid ash depositing in tube.
4. Equipped with economizer, make full use of the heat of flue gas, decrease the exhaust smoke temperature, increase thermal efficiency.
5.Equipped with reliable boiler auxiliaries,such as international famous brand water pump(Grundfos, CNP), Siemens brand electric control elements, Fleck brand water softemner from USA, etc
6. Adopt the latest boiler technology, 100% flaw detection test, high quality, and long working life, low maintenance fee.
This steam boiler is used for producing desired steam for product manufacturing process in the weave factory, printing and dyeing, papermaking and other industry like: food, rubber, plastic, chemical, pharmaceutical, etc, and for heating room and bath in factories, departments, hotels, schools, restaurants, services industries etc.
