The COVID-19 is spreading rapidly across the world in 2020. As important weapons that can isolate viruses and ensure the safety of medical personnel, medical gloves and protective clothing are in short supply. At this critical time, ZOZEN reached cooperation with Ansell, an American protective material enterprise. In order to provide sufficient heat source for its production lines of medical gloves and protective clothing quickly, ZOZEN gave top priority to the production and delivery of the order of Ansell.
Sichuan Kailiwei Technology Co., Ltd. is mainly engaged in the production and sales of tires. Steam as a main heat source plays an important role in the production process of tires. ZOZEN SZS series gas-fired boiler has sufficient and stable output of steam, which can meet the energy requirement of Kailiwei. In addition, the combustion chamber adopts a membrane water wall structure. The flame is burning in slight positive vacuum condition, which insures a clean operating environment. Meanwhile, the spiral finned tube economizer and condenser are equipped to improve the thermal efficiency to more than 98%.
ZOZEN WNS series gas-fired boiler has a compact structure. The boiler is stable and reliable. It adopts a large-diameter corrugated furnace to ensure sufficient steam storage space and heating area. The heat transfer coefficient of threaded flue tubes is 1.2 times higher than that of ordinary flue tubes. Besides, energy-saving devices were equipped at the tail of the flue to improve the inlet water temperature, reduce the exhaust gas temperature and increase the thermal efficiency to more than 98%, which realized the goal of energy saving and emission reduction for many locomotive depots.
ZOZEN has always been devoted to the improvement of quality and service. According to the actual working conditions of Changchun Huatao, ZOZEN not only reasonably designed the WNS series gas-fired boiler system but also completed the lean Manufacturing of the boiler. From the blanking, drilling, welding to bending, all the processes adopted advanced technology to achieve refined production. It is the rigorous attitude to detail that makes the high quality and high performance of ZOZEN.
At present, the two sets of SZS series gas-fired boilers have arrived the project site of Baoding Swan New Fiber Manufacturing Co., Ltd. The hoisting of the boiler proper has been completed smoothly. And, the boilers have entered the auxiliary infrastructure construction phase. ZOZEN installation team will strive to complete the project instruction within the agreed time and ensure the smooth delivery of the EPC turnkey project.
In response to the question, senior engineers who have engaged in industrial boiler technology analyzed the essence of energy-saving and environment-friendly boilers from four aspects, including the condition of fuel combustion, boiler heat dissipation, exhaust temperature and emission indicators.
ZOZEN fully considered the effects of altitude and atmospheric pressure on gas-fired steam boilers when designing the boiler system solution. On the one hand, owing to the decrease of atmospheric pressure, the combustion speed of fuel slowed down. The designers of ZOZEN properly increased the furnace volume and the convective heating surface area to ensure the heat transfer effect. On the other hand, the air volume and pressure should be modified when selecting a burner, which can ensure the boiler output and the thermal efficiency of the entire boiler system.
In 2019, the total value of imports and exports of Chinese private enterprises increased by 11.4% compared with the same period last year, which accounts for 42.7% of Chinese total foreign trade value. With an export value of more than 50% of Chinese total foreign trade value, the private enterprises surpassed foreign enterprises for the first time and became main members of Chinese foreign trade. As a private enterprise with over 30 years of history, Wuxi ZOZEN Boilers Co., Ltd. has developed into a leading industrial manufacturer. With excellent foreign trade performance in 2019, ZOZEN achieved a historic breakthrough.
