产品说明Introduction：
锡能SZS型系列水煤浆蒸汽、热水锅炉是新一代环保产品。具有燃料成本低和污染物排放低的特点，是燃油、燃煤锅炉的最佳替代产品。该系列锅炉为自然循环、室燃水管蒸汽锅炉，微负压燃烧，平衡通风。本体采用纵向布置得上、下两只锅筒，燃烧器布置在前墙，水煤浆在炉膛内充分燃烧（燃烧效率>98%），产生的高温烟气经炉膛出口横向冲刷对流管束，再经布置在锅炉后部的空气预热器换热，通过脱硫除尘器的处理，最后由引风机将烟气送至烟囱排入大气。
水煤浆燃烧效率（>98%），锅炉设计热效率高（接近90%）；
排放符合国家《锅炉大气污染物排放标准》一类地区环保要求；
采用前置稳燃炉膛结构和合理的炉膛截面、容积，使产品能适应多种水煤浆的燃烧，并有效控制炉膛的结焦现象。

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.
