circulating fluidized water boiler, ZOZEN Boiler, a competitive industrial boiler manufacturer in China, answers your questions

On August 25 of 2020, Wuxi ZOZEN Boilers Co., Ltd. officially held the quality management mobilization meeting. The basic design department, research and development department, process improvement department, equipment department, production department, quality assurance department, purchasing department, material planning department, all workers at the production lines and related leadership attended the meeting.

The COVID-19 is spreading rapidly across the world in 2020. As important weapons that can isolate viruses and ensure the safety of medical personnel, medical gloves and protective clothing are in short supply. At this critical time, ZOZEN reached cooperation with Ansell, an American protective material enterprise. In order to provide sufficient heat source for its production lines of medical gloves and protective clothing quickly, ZOZEN gave top priority to the production and delivery of the order of Ansell.

ZOZEN’s molten salt boiler is a kind of boiler that uses a mixture of molten potassium nitrate and sodium nitrite as heat transfer medium. It is a kind of straight-flow special industrial boiler that uses a molten salt circulating pump to force liquid phase circulation, transfer the heat energy to heating equipment and then return to the boiler for further heating circulation. It is highly-efficient and energy-saving with a thermal efficiency of over 95%, and it also can obtain an ultra-high working temperature of 350-580℃ under a lower operating pressure. The whole boiler system is mainly composed of molten salt circulation system, combustion system and heating system.

ZOZEN boilers adopt the ultra-low nitrogen burner with flue gas recirculation method to realize low NOx emission. Adding flue gas to the combustion air to reduce the oxygen content in the combustion air and lower the flame temperature at the combustion center, so as to greatly reduce the generation of NOx. At the same time, superimposed use of world advanced technologies such as staged combustion of ultra-low nitrogen burner and internal flue gas circulation realizes the stable and low emission of NOx.

Boiler parts undergoing X-ray inspection of welding seams

In the production process, the CNC rate of cutting materials of ZOZEN Boiler has reached over 80%, which provides a strong guarantee for the quality of boiler welding and assembly. Compared with flame cutting, the underwater plasma cutting used by ZOZEN Boiler has no deformation and splashing, which further improves the assembly accuracy of boiler components, thereby realizing the precise assembly of the entire boiler. In addition, in terms of pre-welding treatment, ZOZEN Boiler strives for excellence. The three processes of grinding and rust removal, edge milling, and chamfering on vertical lathe can eliminate a large number of pores in the welding seams to ensure the welding quality.

ZOZEN General Manager introduced the manufacturing technique

Nantong Kedi Medical Material Technology Co., Ltd. is engaged in the research, development and production of products such as medical non-woven fabrics, dressings, wound care materials, surgical sanitary products, etc. The products are very popular in the market. In July 2019, Kedi Medical Material decided to expand the production project of processing 8,000 tons of medical non-woven fabrics. As an important piece of equipment of the hot-rolled non-woven fabric production line, the performance of energy saving and high efficiency of gas-fired thermal oil heaters will directly affect the product quality and production efficiency of Kedi Medical Material. With advanced production technologies, scientific testing methods and considerate after-sale service, ZOZEN provided Kedi Medical Material with the YQW series horizontal thermal oil heaters, circulating fluidized water boiler.

In the future, ZOZEN will continue to play its own Advantages in the field of industrial boiler manufacturing and provide high-quality boiler products for more enterprises to lay a solid foundation for development, circulating fluidized water boiler.
