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.
This time, Shanghai High-New Science & Technology Development Co., Ltd. selected the ZOZEN YQW series gas-fired thermal oil heater and supporting waste heat boiler for its project in Ethiopia. To ensure the hot-pressing quality of the wood-based panels, the temperature of the hot-pressing board surface should be as uniform as possible. Therefore, High-New Science & Technology set clear requirements that the oil temperature and operation of the thermal oil heater should be stable. This series of boiler adopts a waste heat boiler to recover high-temperature flue gas. The team generated through the heat exchanges of the waste heat boiler can heat the mill, rubber making machine and other facilities that require steam heat source. The waste heat boiler not only further improves the fuel utilization, but also improves the overall thermal efficiency of the heater to more than 95% and reduces the operation costs. In addition, many advanced facilities independently developed by ZOZEN provide a
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
In response to national environmental protection policies and initiatives for energy conservation and emission reduction, many printing and dyeing companies have technically reformed coal-fired boilers on their original production line. Among them, Wujiang Lianhua Dyeing and Finishing Co., Ltd. was established in 2002, and has now developed into a large-scale production enterprise integrating weaving, dyeing and finishing, printing and import and export trade.
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.
A steam boiler is an important equipment in rubber industry, proving adequate steam support for multiple production processes including drying, profiling and vulcanizing. Jiangsu General Science Technology Co., Ltd. is a modern high-tech enterprise specializing in R&D, production and sales of tires, which is a subsidiary of Hongdou Group. It is one of the leading companies in China's all-steel heavy-duty tire market.
The processes of printing and packaging cartons need a lot of steam heat source, hence, the performance of a steam boiler has a direct influence on the production lines of cartons. Nanjing Shengxi Packaging and Printing Co., Ltd., established in 1981, is one of the backbone enterprises of paper industry in Nanjing. As a professional enterprise specialized in manufacturing cartons and color boxes, Nanjing Shengxi Packaging and Printing Co., Ltd. employs four production lines, providing all kinds of packaging products for Nanjing Cigarette Factory, Coca-Cola Company, Philips Lighting and Mengniu Dairy. With the increasing scale of production, the company's demand for steam is growing day by day; meanwhile, the increasingly stringent environmental requirements are driving the company to transform into "green printing and packaging"; obsoleting old equipment and introducing energy-efficient boiler had been their top priority. During the communication, the manager of ZOZEN learned that the
ZOZEN heating boilers have the characteristics of high efficiency, high durability, energy conservation and environment protection, ensuring the smooth heat supply for all walks of life. Shenyang Space Xinle Co., Ltd., established in 2000, mainly manages the research, development and manufacture of spaceflight products. As the problem of environmental pollution is becoming more and more serious, the national government has strengthened environmental governance, energy co...
