产品说明Introduction：
散装燃煤热水锅炉有DHL型和SHL型，DHL系列散装锅炉为单锅筒横向布置水管散装锅炉。SHL系列散装锅炉为双锅筒横向布置水管散装锅炉。锅炉由上锅筒、水冷壁、对流管束、钢管式省煤器、管式空气预热器等部件组成。锅炉前部由水冷壁组成炉膛，并由前后水冷壁构成前后水冷拱，水平烟道内设置对流管束，锅炉尾部布置钢管式省煤器和管式空气预热器。燃烧设备采用鳞片式不漏煤炉排，分仓室通风结构，调节灵敏，炉排由无级变速齿轮箱驱动。锅炉散装出厂，工地现场组装。
DHL型、SHL型系列散装锅炉具有出力足，热效率高；煤种适应性强；安全可靠，炉内消烟除尘好等优点。广泛用于集中供热的领域。 

WNS automatic oil(gas)-fired steam/hot water boiler is the horizontal,three-return,fire-return,fire-tube boiler,mainlu consisting of housing,tank,diversion smoke chamber and fire tubes.Boiler can use light oil,heavy oil,natural gas,liquefied gas and urban coal gas.
The wet-backj corrugated tank can effectively reduce the thermal stress and improve the safety and life of boiler.
Heatingj areas are laid summetrically for reasonable pressure and expansion.
Sound layout of heating areas ensure good water circulation and heat ecchange,optimizing the effect of heat transfer and increasing the heating efficiency.
Steam boiler integrates the lower-level combustion chamber to expand the range of safe water level and stesm space in the boiler and to guarantee the good-quality steam.
Full butt-welding wet-back structure can avoid the rear wall from damage of hot fume and provide the reliable operation of boiler.
Select the worldly well-known burner and advanced automatic control systerm for more stable combustion,easier operation and safe and more reliable running.

产品范围Scope：
供热量7-116MW，压力1.25-1.6Mpa，出口/进口水温115/70，130/70，130/90，150/90
