4tph DZL Chain Grate Steam Boiler Introduction
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 4tph DZL chain grate steam boiler has realized the high efficiency and low emissions goals. DZL series steam 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 1982, New Hope Group with an annual revenue of more than 130 billion yuan has nearly 700 companies and 80,000 employees around the world. Having started out as a feed manufacturer, New Hope Liuhe Co., Ltd, a branch of New Hope Group engaged in the 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 Indonesia introduced the high-quality and high-efficiency DZL series coal-fired steam boiler to provide efficient and reliable heat source guarantee for feed production.
