With its after-sales service system integrating maintenance service, information feedback, spare parts supply and technical training, ZOZEN Boiler has truly responds in time and solved problems quickly.
The tube end forming machine is a kind of processing and forming equipment used for tube expanding, necking and shrinking under normal conditions. It is widely used for the processing and forming of boiler stainless steel tubes. The boiler components with high processing precision are the quality assurance of boiler welding and assembly. ZOZEN introduced the advanced tube end processing equipment which adopted the PLC control system and hydraulic drive, which could complete the necking of stainless steel tube ends with high efficiency and safety. It was also wear-free and had good product repeatability.
At the 150,000-square-meter production base of ZOZEN Boiler, ZOZEN foreign trade sales manager was conducting live broadcast with Thailand's customers. Through the mobile phone network, ZOZEN showed the CNC blanking, CNC plate rolling, longitudinal and circumferential welding production lines to Thailand’s customers. In the blanking workshop, ZOZEN CNC vertical lathe was beveling the boiler drum heads with high processing precision, which can effectively improve the production efficiency and overall processing level of boilers.
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.
Interested customers from Hubei province visit ZOZEN Boiler factory for field investigation and deputy general manager introduces the company profile of ZOZEN Boiler and advantages of SZS series gas-fired boiler. Its boiler proper adopts D-model structure. One side is furnace and the other side is convection heating surface. It also adopts membrane wall structure, foreign advanced burner, economizer and condenser at the end of flue gas duct, which can lower the exhaust gas temperature to 60 ℃, enhance the thermal efficiency to 98% and above, and reduce the emission of NOx to less than 30mg/Nm3. This equipment is featured by energy-saving, eco-friendly, safe, highly-efficient and easy to operate and maintain. Its automatic control system can also realize unattended operation.
In response to increasingly serious environmental problems, Ji Xiang Ju Food decides to purchase low NOx and eco-friendly gas-fired steam boiler. To meet the new requirements, ZOZEN Boiler customizes the boiler system and recommends SZS series low NOx steam boiler to ensure the sufficient heat supply for Ji Xiang Ju Food's production line. This series of gas-fired boiler adopts D-model full membrane wall structure and combustion chamber adopts narrow-spacing tube membrane wall with good air impermeability to reduce heat loss and enhance the thermal efficiency to 98% and above with the economizer at the end of flue gas duct.
ZOZEN CNC lathe can automatically measure and compensate for tool wear and other errors during machining, improve production efficiency and product quality, reduce scrap rate and costs.
In the petroleum industry, steam is the main factor affecting the energy consumption of enterprises. Jinxi Petrochemical is affiliated to China National Petroleum Corporation. ZOZEN provided the company with SHL series field assembled water tube steam boiler. This series of boilers has wide coal adaptability, the boiler water circulation adopts all-natural circulation, and each heating surface has relatively independent down comers to supply water, ensuring the safety of the overall water circulation. The large furnace design can extend the residence time of the flue gas in the furnace to make the full combustion of the fly ash and combustible gas. In addition, the flag pattern heating surface absorbs the temperature of the flue gas to a large extent, which improves the thermal efficiency of the boiler.
