ZOZEN has focused on the research and development of chain grates for years and has obtained a number of patent technologies. With thermal efficiency over 82% and NOx emissions less than 100mg/Nm3, ZOZEN DZL series boilers have realized the high efficiency and low emissions goals. DZL series boilers adopt horizontal single-drum structure and a chain grate and take the lead in adopting arched tube plates and threaded smoketubes to increase heat conduction. The heat transfer coefficient of threaded smoke tubes is 1.8 times higher than ordinary tubes. In terms of manufacturing processes, ZOZEN adopts the pre expansion of smoke tubes and tube plates to eliminate the gap between them, and then adopts the welding process of argon arc automatic welding to effectively eliminate the stress and prolong the service life of the boiler. With above advantages, ZOZEN has been one of the most popular industrial boiler brands in the feed industry.
Shandong Minghao Chemical Co., Ltd. specializes in the research and development of C4 deep processing technology and production, mainly include MTBE, isobutylene, polyisobutylene and other products. As one piece of the high-efficiency and energy-saving heating equipment on the production line, the thermal oil heater can achieve precise temperature control and has functions such as over-temperature alarm, low oil level alarm and over-pressure alarm. After numerous inspections and investigations, Minghao Chemical finally chose Wuxi ZOZEN Boilers Co., Ltd. as its equipment supplier.
During the deep processing of manganese ore, the industrial boiler provides sufficient heat source power for the purification process. CITIC Dameng Mining Industries Limited is a large-scale multinational enterprise group that integrates mining, processing and smelting of manganese products. It is also an important platform for CITIC Group to develop manganese ore resources and an important worldwide supplier of manganese products. As of now, CITIC Dameng Mining has 16 branches at home and abroad. Among them, Daxin Manganese Mining Branch officially signed a contract with Wuxi ZOZEN Boilers Co., Ltd. for the YLW thermal oil heater in 2017.
ZOZEN has accumulated a good market reputation in the Fujian industrial boiler market, providing reliable and stable steam heat source guarantee for many textile printing and dyeing enterprises. Among them, ZOZEN WNS series gas-fired steam boiler has the characteristics of durability, high efficiency and low consumption, which greatly reduce the production cost of textile enterprises and effectively improves economic benefits. During the manufacturing stage, ZOZEN advanced automatic production lines ensure the quality of the welding and assembly of the boiler, reduces the assembly stress and prolongs the service life of the boiler. During the installation and commissioning phase, the large-diameter corrugated furnace of the WNS series gas-fired boiler, the threaded flue pipe for enhanced heat transfer, and the condenser added at the end of the flue effectively improve the heat transfer effect and ensure that the overall thermal efficiency of the boiler is over 98%.
ZOZEN WNS series gas-fired hot water boilers are widely used in industries such as central heating, hotels, and hospitals. This series of gas-fired boilers adopts a wetback structure. The large-diameter corrugated furnace can not only effectively absorb the thermal expansion, but also increase the radiant heating area. With the advanced combustion equipment, this series of gas-fired boilerscan ensure the full combustion of the fuel, and the thermal efficiency can reach over 98%. And the WNS series boiler is a package boiler, which is fast to install and saves a lot of installation and capital investment costs. In terms of quality assurance, ZOZEN has established a strict quality management system. Each boiler needs to undergo strict quality inspection procedures to complete the final assembly.
In the manufacturing process of automobiles, the painting process has the effect of rust prevention, corrosion protection and decoration. The metal surface treatment before painting and the painting process require the heat source provided by the steam boiler. ZOZEN WNS series gas-fired steam boiler obtains advanced manufacturing technology. The fully automated production line ensures the uniform size of the boiler components, realizes the assembly between the components, which effectively extends the service life of the boiler. In addition, in order to improve the overall thermal efficiency of this type of boiler, ZOZEN technicians have improved the boiler design. Large-diameter corrugated furnace and high-efficiency heat-conducting threaded tubes, combined with the energy-saving device at the tail of the flue, ensure that the exhaust gas temperature below 60℃, and the thermal efficiency is as high as 98%, which reduces fuel costs for enterprises.
Sihai Dyeing and Finishing knew very well that an energy-efficient boiler can significantly reduce operating costs and improve economic efficiency. After comparing many industrial boiler manufacturers, Sihai Dyeing and Finishing chose ZOZEN as its boiler supplier. The technical advantages and advanced manufacturing processes adopted by ZOZEN have become the powerful guarantee for the high quality of gas-fired boilers, in terms of boiler gas consumption, thermal efficiency and low emission of NOx. In addition, the automatic control system of ZOZEN not only greatly reduced the workload of the boiler operator, but also ensures the safe and stable operation of the boiler.
ZOZEN has always been committed to continuously improving the thermal efficiency of gas-fired boilers. WNS three-pass condensing gas-fired steam boiler is an environmentally friendly boiler product of ZOZEN. With advanced low NOx burner, the boiler thermal efficiency can be as high as 98% while achieving ultra-low emission of NOx≤30mg/Nm³. After the fuel is fully combusted in the large-diameter corrugated furnace, the high-temperature flue gas flows backwards to the second pass along the furnace through the reversal chamber , that is, the threaded smoke tube bundle area; After convective heat transfer, the boiler flue gas temperature gradually decreases and goes to front smoke box and turns to 3rd pass, that is, the smooth tube bundle area; Finally, the flue gas enters the economizer and condenser through the rear smoke box, and flows into the chimney and is exhausted into the atmosphere.
