1 WNS Series full-automatic oil burning boiler and gas fire- boiler are used in accordance with international classical structure;Corrugated furnace pipe is used for combustor with lower layout,which effectively increases the heat  exchange area and reinforces the turbulent flow delivery high temperature fume,and simultaneously,releases the shortening life of equipment caused by expansion with heating and contraction witn cooling.

2 Smoke tube with three-pass structure should be arranged symmetrically ,to guarantee the optimum state of heat exchange area and heat transfer efficiency .provied with full wet-back layout,it ensures the safety operation of boilers,reducing  your losses caused by repair and maintenance.

3 Full-automatic operation is used for controlling boiler,and computer program controls combustion with full automation; The steam boiler characterized by ignition and blowout of water-level with self-control,automatic protection for the overpressure  of steam by high/low water level,while hot-water boiler is characterized by overheat , overpressure , and ULValarmimg protection to ensure the safety running for the combustion of boiler.
