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.
In the heavy machinery manufacturing industry, the processes of smelting, pouring, and producing finished castings consume a large amount of steam. ZOZEN superheated steam boiler can meet the temperature requirements of these process.
Hebei Anguo Modern Traditional Chinese Medicine Industrial Park takes modern Chinese medicine and healthy food as the leading industriies. The industrial clustering advantages and perfect infrastructure conditions have attracted many enterprises such as Tong Ren Tang, Tasly and China National Traditional Chinese Medicine Co., LTD. The concentrated supply of high-quality steam provides sufficient heat for the drying, extraction and stewing of traditional Chinese medicines. Therefore, these enterprises have strict requirements on the performance in various aspects of steam boilers.
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.
Sichuan Energy Investment has always formed a profound cooperation with ZOZEN. As an important window for opening up to the northeast of China and participating in the international specialization, Suifenhe has developed into a large-scale Russian wood import and distribution center. With the rapid development of the wood import and export processing industry, the ZOZEN SZL series biomass steam boiler project was installed here, providing concentrated steam for wood drying of wood processing enterprises in the Sino-Russian trade zone.
As one piece of important equipment for the water purification material production line, the thermal oil heater plays the role of providing heat energy in the production process of the water purification agent. Chongqing Lanjie Guangshun Water Purification Materials Co., Ltd. was established in 2009, mainly producing and selling industrial water chemical treatment agents and urban sewage chemical treatment agents.
Veolia (Harbin) Thermal Power Co., Ltd. was established in 2003 and is a Sino-foreign joint venture controlled by Veolia Group. The company's main business is to supply heat to the southwestern part of Harbin. The current heating area is about 19 million square meters, which ranks the top three in Harbin. In order to ensure the heating effect, Veolia Thermal Power decided to introduce the fully automatic gas-fired hot water boilers featuring environmental protection, ensuring that the boilers meet the needs of centralized heating as well as the flue gas meets the standard discharge.
