Nantong Everlasting Foodstuffs Co., Ltd. is a professional foreign trade enterprise, specializing in the production and processing of canned food. The steam boiler plays an irreplaceable role in the production of canned food. In order to ensure that canned food can be preserved for a long time without deterioration, it is necessary to sterilize the canned food with high temperature and high pressure steam. Therefore, a set of steam boiler system with stable operation, high efficiency and energy saving will directly affect the product quality.
Changshu Xinda Weft Knitted Fabrics Factory, established in 2003, is mainly engaged in the manufacturing of weft knitted polyester garment accessories, printing and dyeing of textile fabrics, and dyeing processing of loose wools, wool tops and cheeses. Its weft knitted fabrics with good elasticity, extensibility, softness and wrinkle resistance are favored by many customers. In order to meet the increasing market demands, Xinda Weft Knitted Fabrics Factory decided to expand the production and improve the production equipment including supporting heating equipment by purchasing a set of high-efficiency and energy-saving steam boiler. After investigating the boiler products on the market, Xinda Weft Knitted Fabrics Factory finally ordered a set of WNS series three-pass gas-fired steam boiler from ZOZEN Boiler who had completed the delivery recently.
In order to realize green production and environmental protection effects, Longwang Food decided to purchase the natural gas steam boiler and sets strict requirements for the eco-friendly performance of boiler. After knowing the huge steam demands of Longwang Food's diary and soybean products production lines, ZOZEN Boiler recommended the SZS series gas-fired saturated steam boiler which has sufficiency output, high thermal efficiency and outstanding eco-friendly performance.
Bioland Environmental Technology Group Co., Ltd., founded in 2004, is a high-tech enterprise specializing in integrated garbage treatment and equipment manufacturing. It is also a professional environmental protection company with high qualification in the solid waste industry. As a member in the environmental protection industry, Bioland Environmental Technology Group has been actively responding to the national call of energy saving, emission reduction, environmental and blue sky protection. It removed the outdated production equipment and introduced the highly efficient and eco-friendly WNS series gas-fired steam boiler produced by ZOZEN Boiler as the heating equipment.
This series of circulating fluidized bed is low-temperature combustion. It can desulfurize directly during the combustion process. Besides, the technology and equipment are simple and economic, and the desulfurization efficiency is high. Meanwhile, high temperature cyclone separator in combination with the design of big furnace and low flow rate prolongs the time of coal particles stayed in the furnace, which can ensure complete combustion of coal and effectively improve the thermal efficiency of boilers. In addition, multiple baffle plates are designed on the convection heating surface, which increases the flue gas flow and reduces the dust. Moreover, serpentine tube economizer and air preheater further improve the overall thermal efficiency of the boiler to more than 89%.
This time, Jilin Deda purchased a branch of ZOZEN WNS series gas-fired boilers for demands of meat production and workers' heat supply. This type of gas-fired steam boilers adopts horizontal internal combustion wetback structure with novel design and rational structure. The burner flame is burning in large-diameter corrugated furnace in slight positive vacuum condition. It combined with high-efficient threaded smoke tubes and scientific furnace heat preservation design that can effectively improve thermal efficiency to more than 98%, which is superior to the national Level 1 energy efficiency standard and can realize the expected energy-saving goal of Jilin Deda. Besides, the advanced automatic control system can realize automatic start-stop, load adjustment, water supply and other operations according to the demands of users. With features of easy operation and low failure rate, the control system is both safe and reliable.
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.
Founded in 1958, Changchun University of Science and Technology has three campuses with a building area of 627,000 square meters and a total of 29,820 students. Therefore, the boiler plays a non-negligible role in ensuring the daily needs of teachers and students.Facing the severe situation of environmental protection, Changchun University of Science and Technology decided to upgrade the original boilers. ZOZEN won the trust of Changchun University of Science and Technology with its advantages o...
