After numerous inspections and investigations, we chose ZOZEN as the steam boiler supplier of our Indonesia branch. At present, ZOZEN DZL series steam boiler had been 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.

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.
