ZOZEN has focused on the research and development of chain grates for years and has obtained a number of patent technologies. With thermal efficiency over 82% and NOx emissions less than 100mg/Nm3, ZOZEN DZL series boilers have realized the high efficiency and low emissions goals. DZL series boilers adopt horizontal single-drum structure and a chain grate and take the lead in adopting arched tube plates and threaded smoketubes to increase heat conduction. The heat transfer coefficient of threaded smoke tubes is 1.8 times higher than ordinary tubes. In terms of manufacturing processes, ZOZEN adopts the pre expansion of smoke tubes and tube plates to eliminate the gap between them, and then adopts the welding process of argon arc automatic welding to effectively eliminate the stress and prolong the service life of the boiler. With above advantages, ZOZEN has been one of the most popular industrial boiler brands in the feed industry.
In the pharmaceutical industry, a large amount of steam generated by boilers is required to sterilize the instruments and equipment at a high temperature, and the heat source provided by the boiler is inseparable in the processes of drying and cooling of the drugs, tableting and granulating. Zhengzhou Lingkong Biomedical Park has established a service support system covering innovative research and development and mass production of pharmaceutical companies. It is an innovation and entrepreneurship base for life science and biotechnology research and development in Henan Province.

Plenty of steam is needed in the milk powder production process of sterilizing, concentrating and drying; therefore, a stable steam boiler has a direct impact on the milk production quality. Heilongjiang Feihe Dairy Industry Co., LTD., established in 1962, has won the Gold Award of Monde Selection. As hazy weather appears frequently in recent years, air quality issues have aroused great concern of the whole society. The Chinese government has successively launched "coal to gas" and other environ...
Thermal oil heater is a kind of new heat energy equipment with low pressure and high temperature, playing an important role in various industries. Huagang Gas Group is a sino-foreign joint venture enterprise, which established by Kunlun Energy Company Limited and Huabei Oilfield Company. The company is engaged in natural gas, liquefied petroleum gas, blast furnace gas and so on. Due to the stringent quality requirement for pipeline gas in China, all natural gas needs to be decarbonized and des...
As the determination of country to prevent and control air pollution is increasing, various policies have been introduced across the country. Almost every region, the time period and number of boiler renovations have been issued. In order to maximize the cost savings of the company’s operations, most companies will choose to convert coal-fired boilers to gas-fired boilers, and the rubber chemicals industry is no exception. With the increasingly stringent policies and regulations being promulgated in succession, in 2013, Huasheng rubber planning rubber auxiliary energy-saving renovation project, they purchased a 10-ton WNS condensing gas-fired steam boiler at ZOZEN boiler. The condensing boiler is a hull-type three-way pyrotechnic tube structure researched and developed based on the mature technology of the current gas boiler, the heat load of the boiler is low. An additional condenser is installed at the tail of the flue to increase the boiler inlet temperature and reduce the temperatu
The gas-fired replace coal-fired heating project is one of the decontamination projects to improve air quality in Tianjin. As a result, the fifth gas-fired replace coal-fired boilers project in Tianjin city center ware launched.
First, the coal-to-gas conversion project of the Tiantuo Heat Source Plant in Nankai District. The Tiantuo plant is surrounded by empty land to be built. The project plans to dismantle the original 3 sets of 58MW, 2 sets of 29MW coal-fired hot water boilers and 3 sets of 14 MW steam boilers. They build a new gas-fired boiler room on the west side of the existing boiler room, and install 10 sets of 29MW gas-fired boilers with auxiliary equipment, the heating area is maintained at 3.5 million square meters. Through vigorous bidding campaigns, ZOZEN provided 5 sets of 29MW gas-fired hot water boilers (SZS-1.6/130/70-Q) for the Tiantuo Heating Plant with advanced technology and strength in the boiler industry.
Second, Hedong District also undertakes the task of
PT.Lontar Papyrus has built their pulp mill in Sumatra island since 1994.
During manufacture, the raw material needs to be cut, grinded and cooked, as per the capacity rising, the huge power and steam consumption makes the manufacturing cost higher and higher. For making their product more competitive, PT.Lontar Papyrus decided to build their own cogeneration energy plant, high-quality steam is used for making electricity and low-quality steam is used for process. Cogeneration boiler has high requirement for steam quality, pressure, and boiler smooth running. Because it needs to be installed on-site, it also requires the supplier to be profession for on-site installation. After many times visit and discuss, PT.Lontar Papyrus chose ZOZEN coal-fired steam boiler, by cooperating with local agent, ZOZEN full filled this big project successfully. The boiler has been running well and each target are reached too.
