In recent years, various relatively building material companies have developed rapidly with the development of the construction industry. Jiangsu Yuhang Board Co., Ltd. was founded in 1972 and has accumulated production and technology experience in the sheet industry for decades. The company's main products include calcium silicate board, fiber cement board, wood grain cement board, fireproof board, explosion-proof board and so on. Among them, non-asbestos calcium silicate board is well-known in the industry for its green and environmental protection characteristics, and has won praise from customers at home and abroad. As a high-tech enterprise in Jiangsu Province, Jiangsu Yuhang Board has become a key enterprise in the production of fiber cement products nationally based on its own technical advantages and stable product quality. Industrial boilers play an indispensable role as one piece of the important heating source equipment in the manufacturing process of sheet products.
After the boiler was put into operation, the WNS series gas-fired hot water boiler would provide a stable heat source for the heating of agricultural greenhouses and living areas in our Science and Technology Park. The characteristic of high efficiency will greatly reduce our costs of heating supply.
We were very grateful to ZOZEN for giving top priority to the order of our medical materials company during the outbreak of the COVID-19. The prompt delivery not only showed the strength of ZOZEN, but also let us feel the social responsibility and corporate responsibility of a large manufacturing company.
With the increasing environmental problems, environment-friendly gas-fired boilers have attracted more and more attention. In response to the situation, ZOZEN launched the WNS series gas-fired boiler product, which not only had outstanding environmental performance, but also helped many enterprises realize the goal of energy conservation. ZOZEN WNS series gas-fired steam boilers are horizontal wetback fire-tube boilers which have reasonable internal structure. An advanced low NOx burner is equipped with the boiler to reduce the NOx emission to less than 30mg/Nm3. At the same time, the burner can realize automatic air adjustment, which can ensure the sufficient fuel combustion. Through the commissioning of experienced ZOZEN technicians, the burner can achieve a good combustion state. In addition, the boiler has a large diameter furnace, which can further improve the combustion efficiency.
In order to improve the production process, Jiangxi Hetian New Energy Technology Co., Ltd. selected ZOZEN as its heat source equipment supplier. With outstanding energy-saving performance, the WNS series gas-fired boiler provided stable steam heat source support for the production of batteries. This series of boiler adopts the wetback structure. The large-diameter corrugated furnace not only effectively absorbs thermal expansion, but also has sufficient steam storage space and heating area. At the same time, ZOZEN customized the boiler according to the requirement of the user. The boiler adopted a two-pass design. The economizer and condenser were equipped at the end of the flue, which could make full use of the waste heat to increase the boiler inlet temperature, improve the boiler thermal efficiency to more than 98% and save costs for users. It is worth mentioning that ZOZEN not only has advanced production technologies, but also has professional and perfect services.
We conducted a rigorous market research on the industrial boiler market before purchasing the boiler. Finally, we selected ZOZEN which had good boiler quality and professional services. At present, ZOZEN WNS series gas-fired steam boiler had become an important part of our production line. The feature of automatic operation greatly saved labor costs for our company.
After having an in-depth understanding about the industrial boiler market, Yushuwan Coal Mine selected ZOZEN as its boiler equipment supplier. ZOZEN provided a scientific and reasonable boiler solution for Yushuwan Coal Mine including multiple sets of gas-fired steam boilers. The boiler solution not only can meet the requirements of production and living, but also can improve the utilization rate of thermal energy. Meanwhile, every ZOZEN gas-fired boiler adopts a low NOx burner to meet the low NOx emission requirement. In addition, the utilization of staged combustion technology greatly reduces the generation of NOx. And, the flue gas NOx content showed in the third-party EIA test is 14-17mg/m3. The value is far lower than the environmental protection standard of 30mg/m3.
In the face of severe environmental problems and the requirements of the Nanjing Air Pollution Control Regulations, Nanjing Golden Dragon Bus Co., Ltd. decided to purchase a set of high-efficient natural gas steam boiler. After numerous investigations, ZOZEN with strong comprehensive strength and good reputation was noticed. ZOZEN is a large industrial boiler manufacturer. The annual capacity of ZOZEN has reached 25, 000 tons of steam. In addition, the high-quality steam of ZOZEN WNS series gas-fired boiler can effectively ensure the quality of the processes of baking and painting of Golden Dragon Bus. Besides, the large-diameter corrugated furnace of this series of boiler not only enhances the flue gas disturbance, but also improves the heat transfer effect. Moreover, several energy-saving devices are equipped at the tail of the boiler to improve the thermal efficiency of the boiler to more than 98%, which can help Golden Dragon Bus to realized the goal of energy saving and emission
