instant biogas hot water boiler, ZOZEN boiler continuously introduces professional boiler major talents

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.

In March 2019, Wuxi Zozen Boilers Co., Ltd. successfully passed the French BV certification and became an in-depth factory inspection company of Alibaba International Station. Alibaba cooperated with the French BV certification and comprehensively judged companies' product capabilities, quality control, research and development capabilities, and trade capabilities, which further proved that ZOZEN's comprehensive strength is strong, and all indicators fully meet the boiler export certification standards.

The DZL series coal-fired horizontal three-pass water-fire tube chain grate boiler is pre-assembled boiler which is safe and efficient with a thermal efficiency of over 82%. The boiler body is a single drum longitudinal layout. Thread smoke tubes in the drum form the convection heating surface while the drum and water-cooled walls on both sides form the radiation heating surface of the furnace. The combustion equipment adopts the light chain grate. It has the characteristics of wide coal adaptability, small covering area, convenient installation and high thermal efficiency, instant biogas hot water boiler.

The process of dyeing, drying, pressing, sizing, printing and dyeing, shaping and other processes in the textile industry are supported by the steam generated from industrial boilers. SOORTY is one of the largest denim manufacturers in Pakistan. ZOZEN left a deep impression on SOORTY with its energy-efficient steam boiler system solution, and provided the company with one set of 10 tph SZL series coal-fired steam boiler. 

The grate bracket of ZOZEN’s chain grate boilers adopts double-layer structure. The lower layer uses channel steel and the upper layer uses light rail. The upper layer is heated and the lower layer is stressed. It changes the traditional grate bracket using angle steel and friction strips without  deformation. The active grate runs on the light rail with a 72-hour cold test run carried out before leaving the factory to ensure the smooth operation of grate without deviation or jamming, instant biogas hot water boiler.

During the production process, the CNC cutting rate of ZOZEN has reached more than 80%, which provides a strong guarantee for the welding and assembly quality of the boiler. Compared with flame cutting, the underwater plasma cutting used by ZOZEN has no deformation and splashing, which further improves the assembly accuracy between the components of the boiler, thereby achieving accurate assembly of the entire boiler.

Be it a firetube, watertube, hot water, or steam boiler, they are all effective and efficient in their own unique ways. To learn in more detail about the differences between boiler types, visit the section on ZOZEN website.
