7 mw condensing hot water 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.
7 mw condensing hot water boiler, Increase stoker availability of stoker, guarantee boiler safely running. ZOZEN biomass-fired fuel has another character, which is high volatility and low ash content. After combustion, there is almost no ash left on the stoker, so stoker should adopt proper high temperature resistance material to work under high temperature radiation.
At present, the blanking rate of ZOZEN's sheet metal has reached more than 80%, and a large-scale welding and assembly process revolution has been performed. Mechanical automatic welding is used to realize the assembly mold, and gradually reduce the traditional processing methods of scribing assembly and eliminating scribing errors. Meanwhile, the company's use of advanced measurement and testing equipment also provides a strong guarantee for manufacturing high-quality products.
The textile industry is a great energy consumer. As an important heat source equipment on the production line of textile enterprises, the steam boiler system can directly affect the textile quality and economic benefits of enterprises. Hebei Xindadong Textile Co., Ltd. began to implement an international industrial expansion strategy in 2013 and established a production base in Vietnam. ZOZEN Boiler customized the SZL series coal-fired steam boiler system for the company based on the local situation in Vietnam and actual demands of the production line. This kind of boiler has high efficiency, strong overload capacity and wide fuel adaptability.
After the golden period of rapid development, China’s equipment manufacturing industry is undergoing a transformation and upgrading.
