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.
This is ZOZEN thermal oil heater adopts the multi-circuit coil design with sufficient heating surface and good heat transfer effect which effectively protect the burner and furnace wall. The boiler adopts high-quality refractory and thermal insulation materials which can well reduce the heat loss based on the different refractory and thermal insulation structure for areas with different temperatures. In addition, based on the actual conditions, we also add the waste heat boiler, economizer, air pre-heater and other energy-saving equipment to make exhaust gas temperature to less than 90℃ and the thermal efficiency to reach over 95% and to help the enterprise reduce consumption and the costs.
This is gas-fired/oil-fired thermal oil heater from ZOZEN Boiler which is widely used in petroleum, chemical fiber, pharmaceutical, printing and dyeing and other industries that require high-temperature heating. The thermal oil heater adopts heat medium oil to transfer the heat energy. Applying high temperature of heat medium oil, the boiler can realize low pressure and high temperature heating with a working temperature of 320℃. Meanwhile, our thermal oil heater is equipped with the complete device for operation control and safety supervision which can precisely control the working temperature with convenient operation and high safety performance.
Binzhou Xinkeode Technology Co., Ltd. is a private enterprise engaged in the production and sales of neopentyl glycol, sodium formate and formaldehyde. According to the actual situation of Xinkeode’s production lines, ZOZEN Boiler recommended the SZS series gas-fired condensing boiler. This series of steam boiler adopts the large furnace design and advanced burner, which can ensure the sufficient combustion of fuel to improve the fuel use ratio. With the energy-saving equipment at the end of the gas duct, the boiler thermal efficiency can reach 98% and above to save the operating costs.
ZOZEN energy-efficient WNS series gas/oil-fired steam boilers have two-pass and three-pass structures. This series of boilers adopt the large-diameter corrugated furnace and threaded smoke tubes with high heat transfer efficiency. With the economizer at the end of the flue gas duct, they can enlarge the boiler's heating surface, lower the exhaust gas temperature to 60℃ and improve the boiler's thermal efficiency to over 98%. ZOZEN WNS 8 tph steam boilers are applied in the food, chemical and heating industries.
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.
