pass steam packaged firetube boiler, the automatic control system of ZOZEN thermal oil heater realizes precise oil pressure control

After more than 30 years of development, Wuxi Zozen Boilers Co., Ltd. has made outstanding achievements in various industries. Recently, the ZOZEN WNS series gas-fired steam boiler has established a high-temperature sterilization safety line for the production of contact lenses, which has promoted the healthy development of the entire industry, pass steam packaged firetube boiler.

Recently, benefiting from its solid comprehensive strength, ZOZEN reached cooperation with Sinochem Exploration International Petroleum Company, and successfully settled the boiler project in Colombia. SPIC Columbia is a subsidiary of Sinochem Group's petroleum exploration and development business, dedicated to the exploration and development of long-term oil in Colombia. Boilers are essential equipment for oil exploration.

ZOZEN SZL series chain grate boilers have high combustion efficiency, strong overload capacity, wide coal type adaptability. The boiler is mainly composed of upper and lower drums, convection tube bundles, water-cooled wall tubes, downcomers and headers. The upper and lower drums are longitudinal arranged. The combustion equipment adopts the chain grate with chain belt and is driven by a stepless speed change device.

The IoT solution of ZOZEN Boiler has multiple subsystems such as equipment monitoring, expert management and so on. The boiler operator can monitor the overall operating status of boiler in real time through PC, APP and large screen, which realizes the real-time upload of fault alarms and video monitoring. At the same time, a boiler expert management knowledge base is established for common problems and treatment measures during boiler’s operation, which makes it possible for plan checking and expert online diagnosis, realizes the intelligent and precise management of each production base and further reduces the operating cost and improve the economic efficiency of the enterprise, pass steam packaged firetube 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.

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.

In the past three years, ZOZEN Boiler had brought warmth and cleanliness to people in Harbin with outstanding products and professional services. In the next three years, ZOZEN Boiler will continue to provide support for the air pollution treatment in Harbin with a more proactive attitude.
