During the assembly process of ZOZEN WNS gas-fired boiler, the workers will assemble the threaded smoke tube produced in batches one by one according to the specifications. Then, the professional welder completes the automatic welding of the tube sheet.
ZOZEN SZS series gas/oil fired boiler has excellent performance on the environmental protection. It adopts the well-structured large furnace chamber to ensure the sufficient combustion of the fuel. Also, with the advance burner, ZOZEN SZS series gas/oil fired boiler can reduce the NOx emissions.
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.
In 2020, ZOZEN Boiler successfully supplied boilers in Venezuela, Thailand, Afghanistan, Karachi, Zimbabwe and many other countries. Especially in Afghanistan, ZOZEN provided one set of SZL series coal-fired steam boiler for Baheer Group, providing heat source for the paper production line. It successfully passed the environmental protection inspection organized by Afghan government, which had been proved to meet the local environmental protection standards due to the high combustion efficiency and super-clean flue gas emissions.
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.
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.
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.
WNS series gas-fired or oil-fired hot water boiler is smoke-fire tube chamber combustion boiler and adopts two-pass or three-pass structure. It also adopts large-diameter waveform stove furnace with good thermal expansion and safety performance. There are condenser and economizer added at the end of flue gas duct which can improve the thermal efficiency to more than 95% and save boiler's operation costs.
