small capacity pellet boiler, the third-generation of ZOZEN biomass-fired boiler has significant energy-saving and environmental protection effects
In the comprehensive office building of ZOZEN Boiler, Design Department, Technology Department, Production Department, Quality Inspection Department and Marketing Department coordinate with each other to promote the projects in a smooth and quick way. In the modern multifunctional meeting room, there is a lot of domestic and international certification acquired by ZOZEN including the A-grade boiler and BRⅡ-grade pressure container manufacturing licence, ASME “S” (utility boiler), “U” (pressure container) steel seal licence of USA and ISO9001 international quality system certification.

As a well-known brand deeply exploring the industrial boiler industry for more than three decades, ZOZEN Boiler performs well in aspects including technology, quality, market reputation and so on. This time, based on excellent product quality, superior strength and abundant project experience in the auto industry, ZOZEN Boiler won the bid for providing boilers and installation service for the distributed energy combined cooling heating and power system project of BMW Brilliance's Tiexi new plant, small capacity pellet boiler.
ZOZEN DZL series coal-fired steam boiler has sufficient output and high thermal efficiency. The boiler is packaged with a compact structure, so it has relatively low construction costs. The boiler is a horizontal three-pass water and fire tube chain grate boiler. In the single drum with a longitudinal layout, threaded smoke tubes from the convection heating surface, while the boiler drum and water-cooled walls on both sides form the radiation heating surface in the furnace. The boiler thermal efficiency can reach 82% and above.
With thermal efficiency over 82% and NOx emissions less than 100mg/Nm3, ZOZEN DZL series boilers feature high efficiency and low emissions. They adopt single-drum structure and a chain grate. The heat transfer coefficient of threaded smoke tubes is 1.8 times higher than ordinary tubes. In order to expand the capacity, PT. New Hope Indonesia introduced ZOZEN DZL series coal-fired steam boiler to provide efficient and reliable heat source guarantee for feed production.
small capacity pellet boiler, ZOZEN’s biomass-fired chain grate boilers have significant advantages such as wide fuel adaptability, low original emission concentration, low operating costs and simple operation. Based on the development of environmental protection, ZOZEN Boiler has been designing and manufacturing chain grate boilers very early. At present, the company’s biomass-fired chain grate boilers have formed a series of industrial boilers including DZL, SZL, DHL, SHL, etc. They can ensure fuel’s sufficient combustion when burning shaped biomass fuel pellets or directly burning biomass bulk materials. The biomass-fired boilers designed by ZOZEN adopt advanced arch design, original membrane wall structure, special slag removal technology and reasonable grate sealing structure with outstanding performance advantages.
With the application of patented technology in chain grate furnace, ZOZEN has realized the high efficiency and low emission of DZL series steam boilers. The thermal efficiency can reach 82% and NOx emissions can be less than 100mg/Nm3, which not only improves the combustion efficiency but also reduces the operating costs and pollution emissions of enterprises.
In the next five years, with the construction of lean factory, ZOZEN Boiler will strive to become an international industrial boiler manufacturer to show the quality and service of made in China to the world. “Reform for better” will also become the goal of all ZOZEN people, small capacity pellet boiler.
