Jiangsu Dongfang Printing Co., Ltd., founded in 1978, is an enterprise specializing in the color paper product packaging. The company is competitive in technology and has many sets of advanced equipment including the imported offset printing machine, B, E single-tile and three-layer high-speed corrugating lines. Its post-pressing processes also completely realize the automation. The corrugated paper production line is the key production equipment of Dongfang Printing and the forming of the corrugated paper requires sufficient and stable steam supply. Facing the increasingly fierce competition in the carton packaging and printing industry, Dongfang Printing decided to order a set of efficient and stable WNS series gas-fired steam boiler from ZOZEN Boiler to improve the production quality and automation of the corrugated paper production line, so as to enhance the efficiency and save the costs.
Guizhou Shuicheng Mining Co., Ltd. is a large-scale enterprise group focusing on the coal production and processing. Its business also covers the chemical processing of coal, electric power, coal machine manufacturing, etc. The company's mining area is mainly composed of the Shuicheng mining area and Zhina mining area, with rich geological reserves, complete coal types and good coal quality. Its main coal products include washing mixed coal, sieving mixed coal, anthracite and smelting refined coal, which are the ideal coal types for the electric power, chemical, building materials, metallurgy and other industries.

Established in 2002, Fujian Deyun Science and Technology Co., Ltd. is mainly engaged in the research, development and production of lace and subsequent dyeing and finishing service. Its lace is mainly used to produce women's lingerie of various brands. As all know, dyeing and finishing is a kind of chemical process. After the chemical processing, textile materials needs to accept repeated washing and drying processes, which can consume a large amount of heat energy and water. In order to reduce the heat consumption, Deyun introduced a set of YQW series gas-fired thermal oil heater system produced by ZOZEN Boiler. This system has sufficient output and high thermal efficiency, which can meet the high-temperature heat demands of the lace production, dyeing and finishing lines of Deyun.
In the building materials industry, autoclaved aerated concrete slabs and blocks are widely applied because of their characteristics of good heat preservation and insulation capacity, light weight and high strength. Of course, the autoclave curing of autoclaved aerated concrete materials depends on the heat source provided by the industrial steam boiler. Founded in 2011, Tianjin Heyuan Weiye Lightweight Building Materials Co., Ltd. is mainly engaged in the production and sales of autoclaved aerated concrete blocks. In order to further improve the quality of autoclaved aerated concrete blocks and expand the market share, Heyuan Weiye decided to purchase a set of WNS series gas-fired steam boiler produced by ZOZEN Boiler.
This time, by virtue of the low-NOx emission advantage of WNS series gas-fired steam boiler, ZOZEN successfully reached the cooperation with Jiangbei Pharmaceutical. Zhejiang Jiangbei Pharmaceutical Co., Ltd., established in 1993, is a national high-tech enterprise and science and technology enterprise in Zhejiang Province which mainly produces solid preparations, APIs and medical intermediates. The company has a good product group including 7 categories of APIs, medical intermediates and solid preparations that are cardiovascular, central nervous, digestive tract, antiviral, anti-infective, anticoagulant, and anti-osteoporosis drugs.

Its main products are rice flour, glutinous rice flour, rice starch, glutinous rice starch, stuffed straight, which are exported to more than 30 countries and regions in the world and are favored by customers. As is known, a stable heat source and precise temperature control can affect the taste, quality and output of rice vermicelli products. In order to ensure the quality of rice vermicelli, the company ordered the YQL series gas-fired thermal oil heater produced by ZOZEN Boiler to meet the requirements of precise temperature control.
In the carton production process, the steam heating system plays an important role in increasing the temperature of cardboard. With the WNS series gas-fired steam boiler which is high-efficiency, energy-saving, safe and eco-friendly, ZOZEN Boiler has successfully reached the friendly and long-term cooperation with packaging enterprises such as Pacific Millennium Packaging Group and Shengxi Packaging, and has also accumulated abundant project experience. This time, ZOZEN and Chongqing Yongsheng Packaging Co., Ltd. reached the cooperation on the WNS series condensing steam boiler project to provide sufficient and stable steam heat source for the carton and printing production lines.
Since the beginning of 2020, with the support of county government, Luanchuan County Thermal Energy Co., Ltd. has continuously improved the heating equipment and service quality to promote the central heating business in Luanchuan County. In September of 2020, the company organized the public bidding for the second phase of the central heating boiler room project in Luanchuan County. The company planned to introduce a set of energy-efficient gas-fired hot water boiler and clearly required that the NOx emission concentration of the hot water boiler should be less than 30mg/Nm3. This time, due to the high thermal power and good environmental protection performance of the SZS series gas-fired hot water boiler, ZOZEN Boiler successfully won the bid.
