Structural FeaturesThe DZL series of coal-fired steam boilers are single-drum, vertical-type chain-grate 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.
The novel spirally-corrugated fire tubes and arched tube plates enable the boiler to be safely
operated, achieving ideal energy-saving effect and higher heat efficiency.
The air regulation is flexible during combustion, allowing the boiler to be conveniently operated.
The grate design adopts stepless speed regulation, which is convenient, stable and reliable.
The modified furnace arch realizes a strong fuel-adaptability and an ideal burning effect. This series can be quickly assembled and delivered. The installation period is short, greatly
reducing the capital investment.
