The customer project is located in Hainan Province with a total investment of 28 million US dollars in the first phase. After the project is completed, the biomass resources of Yangpu and surrounding cities and counties will be fully used to realize the resource utilization of renewable energy, and the heating steam will be provided for the enterprises in and around the development zone to meet the production needs of relevant enterprises. As the gas-fired boiler supplier of this project, ZOZEN boiler provided a set of gas-fired superheated steam condensing boiler with capacity of 50 tph.
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. At present, the company has become an important base for the production and export of cardiovascular and antiviral drugs in the world.
Heilongjiang Changfeng Coking Co., Ltd., founded in 2014, mainly produces coke, tar, crude benzene and other chemical products. In the second half year of 2019, the company invested more than 60 million RMB to launch a 6 MW coal gas thermal power project which required a set of 45 tph gas-fired boiler and the 6 MW condensing steam turbine generator set. If the project is put into use, it is expected to generate 60 million kWh of electricity per year and form a heat supply network covering 300,000 square meters, which is a municipal-level key industrial project and is highly valued by the local government. However, this set of steam boiler with a rated pressure of 3.82 Mpa and a steam temperature of 450℃ is a kind of A-grade mid-temperature and mid-pressure boiler, which sets high requirements for boiler design and manufacture.
In recent years, incidents related to food safety is nothing new, of which many are caused by unqualified food packaging. Therefore, food packaging safety issues have received wide attention from many food enterprises and the public. Nanjing Yanzhenwang Packaging Materials Co., Ltd., established in 2012, is a Sino-Japanese joint venture engaged in the production and processing of food packaging and other plastic packaging materials, which needs the support of steam heat source. In order to meet the demands of ever-expanding production scale and respond to the increasingly strict environmental protection policies, Nanjing Yanzhenwang Packaging Materials Co., Ltd. decided to replace the outdated production equipment with the eco-friendly boiler with high efficiency and good energy-saving effect to provide stable and safe heating support for the production line of food packaging materials.
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.
Among many industrial boiler products, Bintou Thermal Power selected ZOZEN SZS series gas-fired steam boiler for peak shaving. This series of boiler is designed with longitudinal double drums and " D " type chamber structure. The combustion chamber adopts a membrane wall structure, which has good air tightness, no smoke leakage, and high thermal efficiency. Meanwhile, the tail of the boiler is equipped with flue gas condensation recovery devices to effectively control the exhaust temperature and increase the thermal efficiency to more than 98%. In addition, devices such as explosion-proof doors, flame detectors, water level alarms and water level interlocks are equipped to further ensure the safety of boiler operation.
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%.
