The 3 sets of 29 MW gas-fired hot water boilers serving for Jin-an Thermal Power in Tianjin were installed in 2015. The boiler is a common type for central heating which adopts the full membrane wall structure and a D-type layout. It has the characteristics of micro-positive pressure combustion, no air leakage, low heat loss caused by exhaust gas and high thermal efficiency. During the boiler manufacturing process, ZOZEN Boiler emphasizes that the welding of each baffle must be tight, and the height of welding leg should meet the requirements specified on the design drawing to ensure the leakproofness of the boiler. In addition, ZOZEN Boiler also sets strict welding standards for detailed parts including the door opening and kiln eye to prevent the high-temperature flue gas from leaking.
The immersive foreign language training mode is a language training method with many years of practical experience and successful examples in the world. It refers to the fully enclosed language training in which the target language is used for teaching. As a learning-oriented team, ZOZEN E-commerce department used the immersive English training method. After many practices, it had effectively improved the English level of our staff to help them provide better boiler services for overseas customers.
Continuing the 2020 industrial live streaming mode, ZOZEN Boiler has made the online visit normal. Recently, at the modern production base of Wuxi ZOZEN Boiler, technicians had connected with Finnish customers via the live streaming to show the whole process of the boiler hydrostatic test. Through the live streaming, ZOZEN not only showed the entire panorama of the hydrostatic test, but also showed the operating steps and pressure gauge values on the top of the boiler. The customers were very satisfied.
Among many boiler types, biomass-fired chain grate boiler has the advantages of wide fuel adaptability, low original emission concentration, low operating costs and easy operation. Based on the eco-friendly development thinking, ZOZEN Boiler has long been designing and manufacturing the chain grate boilers. At present, the DZL series industrial boiler adopts the advanced arch design, independently developed membrane water-cooled wall structure, special slag removal technology and reasonable sealing grate structure, which shows an obvious performance advantage.
ZOZEN SZS series oil-fired/gas-fired boiler proper adopts the D-type structure. One side is the furnace, and the other side is the convection heating surface. The partition walls around the furnace body, the partition wall between furnace and convection section, and the front and rear walls all adopt the membrane wall structure. There are foreign advanced burner, economizer and condenser installed at the end of flue gas duct, which can lower the exhaust gas temperature to 60℃, achieve the thermal efficiency of over 98% and control the emission of NOx to less than 30mg/Nm3. This kind of boiler has the characteristics of energy saving and environmental protection, safety and efficiency, simple operation and maintenance, and fully automatic control system which can realize unattended operation.
This is gas-fired/oil-fired thermal oil heater from ZOZEN Boiler which is widely used in petroleum, chemical fiber, pharmaceutical, printing and dyeing and other industries that require high-temperature heating. The thermal oil heater adopts heat medium oil to transfer the heat energy. Applying high temperature of heat medium oil, the boiler can realize low pressure and high temperature heating with a working temperature of 320℃. Meanwhile, our thermal oil heater is equipped with the complete device for operation control and safety supervision which can precisely control the working temperature with convenient operation and high safety performance.
Binzhou Xinkeode Technology Co., Ltd. is a private enterprise engaged in the production and sales of neopentyl glycol, sodium formate and formaldehyde. According to the actual situation of Xinkeode’s production lines, ZOZEN Boiler recommended the SZS series gas-fired condensing boiler. This series of steam boiler adopts the large furnace design and advanced burner, which can ensure the sufficient combustion of fuel to improve the fuel use ratio. With the energy-saving equipment at the end of the gas duct, the boiler thermal efficiency can reach 98% and above to save the operating costs.
ZOZEN energy-efficient WNS series gas/oil-fired steam boilers have two-pass and three-pass structures. This series of boilers adopt the large-diameter corrugated furnace and threaded smoke tubes with high heat transfer efficiency. With the economizer at the end of the flue gas duct, they can enlarge the boiler's heating surface, lower the exhaust gas temperature to 60℃ and improve the boiler's thermal efficiency to over 98%. ZOZEN WNS 8 tph steam boilers are applied in the food, chemical and heating industries.
