boiler in hospitals condensing boiler manufacturer, ZOZEN boiler wins the dual certification of asme and iso

ZOZEN is always committed to doing every detail well and creating value for users. Since the company was founded in 1988, ZOZEN has reformed the traditional production mode of industrial boiler industry and introduced modern science and technology to realize the mechanization, informatization and intelligentization of boiler production line. The fully automatic production lines greatly improve the production efficiency. More importantly, it also enhances the size precision of boiler parts processing and reduces the product quality problems caused by human factors, boiler in hospitals condensing boiler manufacturer.

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 biomass-fired horizontal three-pass water-fire tube chain grate boiler is pre-assembled boiler with a capacity of 2-20 tph (hot water boiler: 1.4-14MW) and a thermal efficiency of over 88%. By extending the furnace arch, increasing the furnace height and adjusting the width and length of grate, ZOZEN takes the lead in solving the problems that easily occur in biomass-fired boilers such as furnace arch collapse, furnace door burnout, hopper tempering and tube wall coking. It has the characteristics of wide fuel adaptability, small covering area, convenient installation and high thermal efficiency.

boiler in hospitals condensing boiler manufacturer, The biomass-fired boilers produced by ZOZEN have wide fuel adaptability to a variety of fuels such as biomass pellets, wood chips, palm shells, straws, etc. According to different fuel characteristics, ZOZEN technicians optimize the design of feed hopper, width and length of grate, speed of grate reduction gears, ratio of primary and secondary air, position and direction of secondary air outlet to ensure the highly-efficient, energy-saving and stable operation of boiler.

The digital management of ZOZEN runs through the entire process. In the drum production workshop, the high-speed CNC drilling machine is operating efficiently according to the instructions of the control system. Thousands of holes can be accurately completed in less than twenty hours. Such a workload requires at least one week of labor.

boiler in hospitals condensing boiler manufacturer, The complete set of WNS series gas-fired hot water boiler system customized by ZOZEN Boiler for Jilin Mingde Education adopts the corrugated furnace which not only increases the strength and flexibility of the furnace, but also enhances the flue gas disturbance to effectively improve the heat transfer effect. The threaded smoke tube with advanced manufacturing technology has been continuously optimized to effectively absorb the flame energy, and its heat transfer coefficient is 1.2 times higher than that of ordinary smoke tube. At the same time, with the additional finned tube condenser at the end of the flue gas duct, the exhaust gas temperature can be lowered and the boiler thermal efficiency can be as high as over 95%. According to the energy efficiency test conducted by the Thermal Energy Testing Center of the Special Inspection Institute, the performance indicators of the WNS series gas-fired boiler are higher than design requirements and have reached the advanced level at home and abroad.

Industrial boiler belongs to special equipment and has high requirements for product safety factors. As the domestic well-known boiler supplier, ZOZEN has advanced mechanical equipment, mature manufacturing process and guarantee of boiler quality. In addition, via the innovation and development of ZOZEN’s professional design team, the structure and material of boiler proper are continuously improved and optimized to greatly extend boiler’s service life. It is also worth mentioning that ZOZEN’s automatic boiler control system with dozen kinds of safety protection interlocks can fully ensure boiler’s safety. In the aspect of environmental protection performance, ZOZEN boilers are also outstanding. The flue gas emission of ZOZEN boilers nearly meets the EU standards. The NOx emission is low to 30mg, which realizes the goal of low-nitrogen emission, boiler in hospitals condensing boiler manufacturer.
