combined heavy oil boiler dealer, with a new technological upgrading, ZOZEN boiler, the gas-fired boiler manufacturer, vigorously enhances the core competitiveness of the enterprise

ZOZEN announced the partnership with Libbey Inc., the global glassware industry giant, on the low NOx gas-fired boilers. As an industrial boiler manufacturer with more than 30 years of history, ZOZEN shares the same development concepts with Libby. The two sides became friendly and trustworthy partners to improve the atmospheric environment.

ZOZEN YLW series thermal oil heater is a kind of horizontal square-coil chain grate boiler. It is pre-assembled, so the chain grate and boiler proper are separated for shipment. The boiler adopts the chain grate for mechanical coal feeding, the forced and induced draft fans for mechanical ventilation and the slag discharger for mechanical slag discharge. During operation, the fuel falls from the coal hopper onto the grate for combustion. The high-temperature flue gas is reflected from the back arch to the front of the furnace and enters the furnace. After the radiant heat exchange, it enters the convective heating surface for convective heat exchange and then goes to the waste heat boiler, air preheater and dust collector. Finally, the flue gas is drawn by the induced draft fan through the chimney and is discharged into the atmosphere.

ZOZEN Boiler has invested a lot of technical force in improving boiler’s energy-saving performance. The structure and operating principle of organic heat carrier boiler cause that the exhaust gas temperature at its end is around 300°C and result in a huge waste of heat energy. In order to reduce heat loss, ZOZEN technicians add a variety of energy-saving devices at the end of boiler’s flue gas duct to improve the overall thermal efficiency of organic heat carrier boiler through the recovery and utilization of high-temperature flue gas, which helps many companies to achieve the goal of energy saving and consumption reduction.

combined heavy oil boiler dealer, The key processing technologies of the steel plate of ZOZEN gas fired boiler, such as the slanting of the steel plate, the circle, and the drilling of the drum, all adopt advanced CNC processing technology to reduce assembly stress and extend the service life of the boiler. Process to ensure welding quality, all longitudinal and circumferential welds are 100% radiographically inspected.

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.

combined heavy oil boiler dealer, There is only one earth. An increasing number of enterprises are constantly striving to build a community of shared future for humanity. In the future, ZOZEN will adhere to the original aspiration of sustainable development, design and manufacture more efficient and environmentally-friendly boilers and explore more boiler system solutions to promote the realization of environmental protection goals.
