    WNS Type Industrial Natural Gas Diesel Oil Full Wet Back Structure Medical Sterilized Boiler

    WNS Type Industrial Natural Gas Diesel Oil Full Wet Back Structure Medical Sterilized Boiler

    Product basic information:

    1. Boiler type: fire tube, smoke tube boiler.

    2. Fuel: natural gas, lpg, lng, cng, diesel, heavy oil.

    3. Pressure: 0-16bar on option.

    4. Structure: three pass, wet back, horizontal.

    5. Boiler capacity: 0.3ton to 20 ton per hour steam vapour.

    Smoke process and Full wet back structure:

    After the fuel and air are fully mixed, they are ignited and burned to produce high-temperature flue gas. The boiler furnace is positive pressure. After the high-temperature flue gas is burned in the furnace, it enters the second return thread pipe bundle through the back combustion chamber, and then passes through the front cigarette box. Into the third return thread pipe bundle, and finally discharged into the atmosphere.

    The boiler furnace, the back combustion chamber and the smoke pipe are all immersed in water. During the flow of the flue gas, these components exchange heat by the temperature difference between the flue gas and the water, and the steam is generated by the main steam valve.

    Product introduce and advantage

    1. Three-return structure: adopts the international popular shell-type three-return ,full wet back structure, combustion chamber large volume design, to ensure the combustion more fully. Fuel combustion in the furnace by micro-positive pressure, high temperature smoke gas along the boiler furnace go backward through reverse flow combustor turn 180°into the first smoke flue tube bundle, pass the oppressive front smoke box then turn 180°into the second smoke flue tube bundle, after the convection heat transfer injection into the atmosphere.
    2. The corrugated furnace: the combustion chamber adopt full corrugated furnace structure, not only strengthen the flue gas disturbance, but also increased the radiation transfer area; not only increase the rigidity of the furnace, but also effectively weaken expansion stress of furnace; both enhance the heat transfer effect, and promote the fuel combustion in the furnace.
    3. The unique pipe and tube sheet welding technology: adopts the first pre-expansion and then all welding, and then expanded connection advanced technology. Both to prevent the pipe gap corrosion, and enhance the welding strength; adopts the high heat transfer coefficient of the screw smoke tube, to strength the convective heat transfer effect, reduce the exhaust gas temperature, improve the boiler thermal efficiency.
    4. Symmetrical activities hinge joint front, back smoke door: easy to open, convenient for repair, clean up.
    5. Wet back structure: the boiler use wet back structure, full pull side butt weld,reliable performance, low maintenance costs.
    6. Rear-view device: rear view device design, easy to observe the combustion situation.
    7. Security: design over-temperature, overpressure, water-shortage, leakage detecting, flameout and other protection functions, boiler operation safe and reliable.
