DZL Series of Coal-fired Hot-water Boilers

Name: DZL Series of Coal-fired Hot-water Boilers
Rating: 5.0 (77 reviews)

Structural Features

The DZL series of coal-fired hot-water boilers are single-drum, vertical-type chain boilers.
The boiler proper mainly comprises a drum, a furnace, a convection tube bank and an economizer, etc.
The single-layered arrangement achieves a compact structure.
Novel spirally-corrugated tubes and arched tube plates are adopted, allowing the boiler to be safely operated, and achieving ideal energy-saving effect and high heat efficiency.
The air regulation is flexible during combustion, realizing a convenient operation.
The grates adopt a stepless speed regulation, which is convenient, stable and reliable.
The modified furnace arch realizes a strong fuel-adaptability and an ideal burning effect.
The installation period is short, greatly reducing the capital investment.

Applications:

This series is mainly used in colleges, hotels and hospitals for supplying hot water and heating.
