Wuxi Pacific Fertilizer Co., Ltd., established in 1994, is a large-scale compound fertilizer manufacturer in East China. The company produces economical and high-quality compound fertilizers with great market demands and sales volume. Considering that compound fertilizers with high concentration and long effect have better market prospect, Pacific Fertilizer decided to enlarge the fertilizer production line via renewing the boiler equipment. After the field visits for a comprehensive understanding, Pacific Fertilizer finally signed the contract with ZOZEN Boiler to purchase a set of WNS series gas-fired steam boiler with sufficient output and high thermal efficiency as the heating equipment on the fertilizer production line.
Weifang Huabao Textile Co., Ltd., founded in 2004, is jointly invested by Changyi Huabao Textile Co., Ltd. and Hong Kong Aosen International Co., Ltd., which mainly engages in the weaving, dyeing and finishing of high-end fabrics. The steaming and drying processes of dyeing and finishing need a continuous and stable heat source. The huge heat energy consumption puts forward higher requirements for the industrial boiler equipment. Therefore, after careful consideration, Weifang Huabao Textile decided to introduce two sets of YQW series gas-fired thermal oil heater from ZOZEN Boiler, which helped the company successfully compete the "coal to gas" project, greatly reduce the energy consumption and further realize the green and sustainable development.
In order to realize the aim of "environmental protection, energy saving, good quality, high efficiency", the company introduced the SZS series gas-fired superheated steam boiler produced by ZOZEN Boiler in 2018, which provided the stable, safe and highly-efficient heat supply for the production line of corrugated paper, effectively enhanced the company's economic benefits and helped the company practice the important social responsibility of protecting the environment.
In order to meet its heating requirements in winter, Ainengju Photovoltaic introduced the ZOZEN DZL series biomass-fired boiler. Being aware of the importance of innovation and development, ZOZEN pays attention to the cultivation of talents and the construction of talent pools all the time. ZOZEN also actively reaches cooperation with universities and research institutes. ZOZEN DZL series biomass-fired boiler is longitudinal arrangement with a single drum. According to the characteristics and fuel rate of different biomass fuel, ZOZEN reasonably arranges the heating surface of the furnace arch, furnace wall and furnace chamber of the DZL series of boiler to ensure the overall thermal efficiency and the normal and stable operation of the boiler.
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.
Confronted with the increasingly severe environmental protection policies, ZOZEN has made progress in the research and development of technologies in recent years. WNS series gas-fired boilers with features of high efficiency and low emissions are preferred by the industrial boiler market. This series of boiler adds a radiant heating surface to increase the heat transfer coefficient. Besides, the boiler adopts high-efficient threaded flue tubes to slow down the flue gas flow rate and fully absorb heat. In addition, energy-saving devices are equipped at the tail of the flue to increase the thermal efficiency to above 98%. The efficiency is superior to level 1 national energy efficiency standard. Moreover, the advanced low NOx burner greatly reduces the emission of NOx to 30 mg/m３. The ultra low emission provides guarantees for clean production and sustainable development of enterprises.
ZOZEN has accumulated a good market reputation in the Fujian industrial boiler market, providing reliable and stable steam heat source guarantee for many textile printing and dyeing enterprises. Among them, ZOZEN WNS series gas-fired steam boiler has the characteristics of durability, high efficiency and low consumption, which greatly reduce the production cost of textile enterprises and effectively improves economic benefits. During the manufacturing stage, ZOZEN advanced automatic production lines ensure the quality of the welding and assembly of the boiler, reduces the assembly stress and prolongs the service life of the boiler. During the installation and commissioning phase, the large-diameter corrugated furnace of the WNS series gas-fired boiler, the threaded flue pipe for enhanced heat transfer, and the condenser added at the end of the flue effectively improve the heat transfer effect and ensure that the overall thermal efficiency of the boiler is over 98%.
The Second Hospital of Jilin University is a third-class & first-grade comprehensive clinical hospital. Hot water and steam are essential energy sources for large comprehensive hospitals, providing adequate steam heat energy support for hospital heating and daily disinfection. Under the background of current energy-saving emission reduction and refined management, the Second Hospital of Jilin University actively responded to the national “coal to gas” policy and decided to replace the old boiler equipment with low efficiency and high emission.
