ZOZEN SZS series gas-fired and oil-fired steam boiler has the advantages of high efficiency and energy saving. This series of boiler adopts double drum with full membrane structure. The SZS series boiler adopts flue gas backflip technology, with the economizer and condenser to improve the thermal efficiency to 98% and above.
WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
ZOZEN will test the leak-proof air pressure of every set of SZS series boiler before delivery. Poor tightness will lead to the leakage of gas fuel, which will not only affect the safe operation of boiler, but also increase the heat loss. The leak-proof air pressure test can secure the tightness of each SZS series gas boiler.
Advanced equipment is the strong support for industrial boiler manufacturers. As an internationally renowned boiler manufacturer, the advanced automated production line in the modern workshop of ZOZEN Boiler not only shortens the manufacturing cycle of the boiler, but also improves the quality of the boiler and extends the service life of the boiler. At the same time, orderly production management and rigorous quality inspection are also an important part of completing the lean manufacturing of boilers. Through the advanced sales mode of live webcast, the strong strength of ZOZEN Boiler is passed on to overseas users through internet. And overseas users are feeling like on the scene!
ZOZEN WNS series oil-fired/gas-fired boiler is a kind of fire tube wetback boiler with a two-pass or three-pass structure. It is equipped with foreign advanced burner, economizer and condenser installed at the end of flue gas duct to lower the exhaust temperature to 60℃, achieve the thermal efficiency of over 98% and control the emission of NOx to less than 30mg/Nm3. It has the characteristics of compact structure, small covering area, short installation period, easy operation and complete automatic control system which can realize unattended operation.
ZOZEN SZS series oil-fired/gas-fired boiler proper adopts the D-type structure. One side is the furnace, and the other side is the convection heating surface. The partition walls around the furnace body, the partition wall between furnace and convection section, and the front and rear walls all adopt the membrane wall structure. There are foreign advanced burner, economizer and condenser installed at the end of flue gas duct, which can lower the exhaust gas temperature to 60℃, achieve the thermal efficiency of over 98% and control the emission of NOx to less than 30mg/Nm3. This kind of boiler has the characteristics of energy saving and environmental protection, safety and efficiency, simple operation and maintenance, and fully automatic control system which can realize unattended operation.
The steam boilers in the hospital are mainly used for sterilization and have certain requirements for the quality and quantity of steam. This time, Shandong Jining Psychosis Prevention and Treatment Hospital purchased two sets of WNS series gas-fired steam boiler from ZOZEN Boiler. This series of boiler has a wide fuel adaptability including natural gas, coal gas, biogas and so on. It also adopts the large-diameter corrugated furnace to ensure the sufficient combustion of fuel and the high thermal efficiency of over 98%. Equipped with the imported low-nitrogen burner, it can easily realize the ultra low NOx emission.
