The ZOZEN SZS series gas/oil-fired boiler workshop is a bustling hub of activity, with skilled technicians and engineers working together to produce some of the industry's most advanced and efficient boilers. The workshop is filled with state-of-the-art machinery and equipment, including automated welding systems, precision cutting tools, and computer-controlled testing equipment. The technicians work meticulously to ensure that every component of the boilers meets the highest standards of quality and safety, from the smallest bolt to the largest furnace.
Before delivery, ZOZEN gas-fired fire tube boiler shell is covered with the stainless steel film to prevent damage to the boiler shell in the process of transportation and installation. The film will be removed after installation. The mirror stainless steel shell of the boiler has the features of low heat loss and beautiful appearance. The pictures show the blank pressing process of the stainless steel materials, which is the previous process of installing the stainless steel film, this process aims to make the material seam much flatter and firmer where surfaces intersect and meet.
ZOZEN WNS series oil-fired and gas-fired boiler is designed with large-diameter corrugated furnace and threaded smoke tube, which makes the heat transfer of the boiler more efficient. With the condenser and economizer installed, the thermal efficiency of the boiler can reach over 98%, which is well received by the market.
Details determine success or failure. The front-line workers of ZOZEN Boiler pay attention to regular maintenance of advanced equipment, effectively preventing equipment performance deterioration or reducing equipment failure probability, and laying a foundation for creating ingenious boiler products.
The ZOZEN 4 tph WNS series gas-fired steam boiler adopts the large-diameter corrugated furnace, which increases the heat transfer surface, reduces the thermal stress and improves the boiler safety. Meanwhile, in order to reduce the heat loss due to exhaust gas and operating costs, ZOZEN also installs the energy-saving equipment at the end of the flue gas duct to ensure boiler's thermal efficiency reaches 98% and above. What's more, WNS series boilers also have the characteristics of fully automatic intelligent control and easy operation to ensure boiler's long-term, safe and stable operation, so they are well received by users at home and abroad.
Relying on the scientific and technological innovation and cooperation with Shanghai Jiaotong University, ZOZEN Boiler develops the new generation of biomass boilers, which not only solves the problems such as the furnace arch and door burning out, hopper burning and feed stopper coking, but also improves the biomass boiler performance.
The boiler is a kind of special equipment and the compressive strength of boiler can directly affect the boiler safety performance. ZOZEN Boiler insists on putting quality in the first place to conduct the strict strength re-inspection on the boiler manufacturing materials newly purchased in order to ensure the compressive strength of boiler fundamentally and escort the safe operation of boiler.
ZOZEN YQW series horizontal thermal oil heater adopts multi-loop coil structure with good safety performance and sufficient heating surface. Meanwhile, ZOZEN Boiler can also design the waste heat recovery system for users to ensure that boiler's thermal efficiency can reach 95% and above. What's more, automatic control system also ensures the safe and stable operation of thermal oil heater to realize the sustainable high-temperature and low-pressure heating supply. In addition, ZOZEN’s gas-fired thermal oil heater is equipped with advanced low-nitrogen burner to ensure that boiler's NOx emission is lower than 30mg/Nm3 to achieve the excellent performance in environmental protection.
