4 ton DZL Chain Grate Steam Boiler Introduction
Over the years, ZOZEN Boiler has focused on the innovative research and development of chain grate and obtained a number of patented technologies to achieve high efficiency and low emission of DZL series coal-fired steam boiler, with thermal efficiency increased to over 82% and NOx emission lower than 100mg/Nm3. DZL series chain grate steam boilers are single pot longitudinal arrangement, the first in China to adopt arch-shaped tube plate and threaded flue tube structure, the threaded flue tube is ZOZEN boilers for many years of research on high-efficiency heat transfer elements, after continuous optimization, its heat transfer coefficient is 1.8 times higher than the ordinary flue tube, increasing heat transfer. In terms of manufacturing process, ZOZEN boilers adopt pre-expansion for flue tubes and tube plates to eliminate the gap between tubes and plates, and then adopt the welding process of automatic argon arc welding to effectively eliminate stress and extend the service life of the boiler. All these advantages have made ZOZEN boilers one of the popular industrial boiler brands in the feed industry.
