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.
China produces more than 700 million tons of crop straw every year, which has become a new source of rural environmental pollution. Hebei Yigao Bioenergy Co., Ltd. and ZOZEN worked together to promote the efficient use of biomass energy such as crop straw. In 2018, Yigao Bioenergy built a number of new production lines, and its products are widely used in papermaking, xylose resin, adhesives, petroleum, pharmaceuticals and other industries. After the project was completed, it is estimated to consume 240,000 tons of biomass straw each year, becoming a demonstration project of comprehensive utilization of biomass straw.
The Second Hospital of Jilin University is a third-class & first-grade comprehensive clinical hospital.
