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.
The hot water boiler is the important equipment for central heating in the northern part of China, which is related to the development of the enterprise and the production and life of the people. Shenyang Third Thermal Heating Co., Ltd. is one of the largest companies of the central heating industry in Shenyang.
China Medical University, (CMU) for short, is located in Shenyang, Liaoning Province. It is a tertiary institution jointly established by the National Health and Family Planning Commission, the Ministry of Education, and the Liaoning Provincial People's Government. According to incomplete statistics, there are 9,157 staff in the school, and 15,548 full-time school students. Such a large group needs to do a good deal of heating and sanitation measures in advance in Shenyang, a particularly long-term winter city. ZOZEN boiler is a fixed-point manufacturer of boilers and pressure vessels approved by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China. This China Medical University's heating equipment purchased a 46MW and a 29MW DHL series angle tube water heater from Zozen Boiler. This series of boilers is a second-generation angle tube type hot water boiler product, which combines the technical characteristics of large-capacity
Jiangxi Ganfeng Lithium Industry Co., Ltd. is a leading company in Chinese lithium industry, specializing in R&D, production, and operation of lithium and deep-processing lithium compound products. In order to improve the production efficiency, Ganfeng Lithuum has purchased a 35-ton energy-saving DHX series circulating fluidized bed boiler in ZOZEN boiler. The furnace has a wide range of combustion adaptability. It can not only burn high-quality coal, but also use various low-grade coal, and the combustion technology is environmentally friendly.
The use of large-tonnage circulating fluidized bed boilers in the lithium industry is a national development trend. The 50-ton circulating fluidized bed boiler is also a medium-sized environmental boiler suitable for the lithium industry. In 2017, Ningdu County Ganfeng Lithium Industry Co., Ltd., a subsidiary of Ganfeng Lithium, plans to invest 17500 tons of battery-grade lithium carbonate production line projects. A 50-ton DHX series circul
Yuanda Cable Co., Ltd.---a high-tech company specializing in the research, product and sale of power cables, branch cables and computer cables. The cable manufacturing process includes three processes of mixing, extruding and vulcanizing. During the extrusion process, overheating easily leads to scorching, when the temperature is too low, it’s hard to gel. In the vulcanization process, bubbles are easily generated when the temperature is too low or too high. The temperature and pressure requirements of every process are different, so the control of cooking temperature and pressure must be precise and adjustable. In 2011, Yuanda Cable had customized a 4-ton DZL coal-fired steam boiler at ZOZEN. This series carried out comprehensive safety monitoring of the boiler’s water level and steam pressure, and it used boiler safety control technology that complied with EU coal-fired boiler standards to ensure boiler operates safer and more reliable. The automatic and interlocking control technolo
