Fuel (gas) steam boiler

WNS series oil (gas) steam boiler with an international classic three return,all butt wet back, corrugated Furnace combined, convection area use threaded tubes and light tube optimized combination of horizontal new boiler, flue gas flow length, good heat transfer. 1,All pull side butt welding, stress the lowest quality and more reliable. 2,Large diameter of stove: Boiler furnace combustion chamber by a large diameter composed of bile and wet back combustion chamber, burning a large space, complete fuel combustion, effective absorption of thermal expansion, large radiation heating . 3,Heat enough: Boilers heating area is large enough, can be fully absorbed effective heat, the exhaust gas temperature is low, heat loss low,ensuring maximum output and high efficiency. 4,Large water capacity , ability to adapt to the load change, output stability; large vapor space volume , the net distance of the interface of soft drinks and exports of steam is high enough , steam humidity was low. 5,Enough safety precipitation time 6,Multi-functional explosion-proof security device 7,Pot easy maintenance 8,Protection of pressure and the water level are reliable : Boiler pressure, water level set multiple control and protection, and over smoke temperature protection, ensure the safety of boiler operation 9,Automatic control level lead ahead: Boiler controller using high quality electronic components, reliable performance. There are three forms of the controller, liquid crystal display type: the Chinese menu, remote control screen man-machine dialogue. One standard configuration for regular
