ZOZEN has focused on the research and development of chain gratesfor years and has obtained a number of patent technologies. With thermalefficiencyover 82% and NOx emissions less than 100mg/Nm3, ZOZEN DZL series boilershaverealizedthehigh efficiency and low emissions goals. DZL series boilers adopt horizontal single-drumstructure and a chain grateand take the lead in adopting arched tube platesand threaded smoketubes to increase heat conduction. The heat transfer coefficient of threaded smoketubes is 1.8 times higher than ordinary tubes. In terms of manufacturing processes, ZOZEN adopts the pre expansion ofsmoke tubesand tube platesto eliminate the gap between them, and then adopts the welding process of argon arc automatic welding to effectively eliminate the stress and prolongthe service life of the boiler. With aboveadvantages, ZOZEN has been one of the most popular industrial boiler brands in the feed industry.
Founded in 1982, New Hope Group with an annual revenue of more than 130 billion yuan has nearly 700 companies and 80,000employees around the world. Having started out asa feed manufacturer, New Hope Liuhe Co., Ltd,a branchof New Hope Groupengaged inthe development of food and modern agriculture,is one of the key leading enterprises in China's agricultural industrialization.In order to expand the capacity, PT. New Hope Indonesiaintroduced the high-quality and high-efficiencyDZL series coal-fired steam boiler to provideefficient and reliable heat source guarantee for feed production.
After numerous inspections and investigations, we chose ZOZEN as the steam boiler supplier of our Indonesia branch. At present, ZOZEN DZL series steam boiler hadbeen successfully delivered. The features of compact structure and simple installation saved a lot of capital construction investment for us, and the characteristics of high efficiency and low emissions of the boiler also reduced operating costs and pollution emissions.
