double drums industry coal steam boiler, all indexes of ZOZEN boiler, the large boiler manufacturer are in compliance with the boiler export certification standards

ZOZEN continuously upgrades the marketing strategy and accelerates the pace of expanding the overseas sales territory. By virtue of the enterprise strength and advantages, ZOZEN has acquired a lot of international certification such as ASME, CE, DOSH and IBR. Its sales network extends from Asia to Africa, Oceania, eastern Europe and America and all series of boiler products are sold to more than 100 countries and regions such as Chile, Mexico, Australia, Singapore, Russia, Kenya, Vietnam, Thailand, Pakistan, Saudi Arabia and so on, which are also favored by users.

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, double drums industry coal steam boiler.

Steam boilers provide thermal energy support in the process of feed granulation. Due to the growing market demands, Zubair Feeds Private Limited in Pakistan decided to purchase one more efficient steam boiler to supply sufficient heat source for the production line. To reduce the fuel costs, the company added rice husk into the coal as boiler fuel for co-firing. ZOZEN provided the boiler solution of SZL series steam boiler system  to meet their actual demand, achieving the goal of promoting the cyclic utilization of biological resources as well as improving the economic benefits. 

With over 30 years of experience in boiler manufacturing, Wuxi ZOZEN Boilers Co., Ltd. has more than 400 kinds of gas-fired boilers, biomass-fired boilers, coal-fired boilers and thermal oil heaters which are widely applied in chemical, food, brewing, heating, paper, printing and dyeing, rubber and other industries. In particular, ZOZEN’s gas-fired boilers can reduce the flue gas temperature to less than 60℃ to improve thermal efficiency and save boiler operating costs for users, double drums industry coal steam boiler.

After the raw materials are transported to the workshop, steel plates will be precisely cut by the plasma cutting machine according to design drawings. The cut steel plates after finishing three processes of rust removing, edge milling and chamfering will be rolled into workpieces for making drums by this advanced four-axis rolling machine. ZOZEN’s CNC rolling machine can complete the rolling of a drum shell within 90 seconds with a largest thickness of 100mm, an out-of-roundness and angular deviation within 1mm. Its advantages include the predeformation and cylindrical rolling of two plate ends via one-time load, arc work, shaping and leveling work on the sheet metal. It has the effects of direct pre-bending, saving time and materials to ensure the smooth progress of next welding process and further ensure the welding quality.

All boilers are subject to damage if proper water treatment procedures are not followed. This is an important consideration both during operation and when the boiler is idle. To avoid damage and costly repairs, monitor water chemistry routinely and ensure that you are supplying your boiler with soft water at all times.
