ylw liquid phase chain grate horizontal coal fired heat transfer fluid furnace factory, the advanced boiler technology of ZOZEN leads the industry

ZOZEN is not just a company that only responsible for manufacturing boilers. Instead, ZOZEN takes responsibility in every step and offers the most effective and fastest service to resolve any problems for customers, including pre-consultation and after-sales services. 

Recently, data from the National Bureau of Statistics showed that China’s industrial boiler output from January to July in 2020 was 184,780.8 tph, a decrease of 24.8% year-on-year, showing a downward trend. Against the background of a sharp decline in the domestic industrial boiler industry, ZOZEN Boiler managed to overcome the difficulties and achieved a slight increase in output, ylw liquid phase chain grate horizontal coal fired heat transfer fluid furnace factory.

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.

The gas-fired boiler is the classic energy-saving and eco-friendly work of ZOZEN Boiler. The boiler has excellent manufacturing technology, reasonable structure and stable performance, which has been widely recognized by customers. Besides, it adopts the imported low-NOx burner from German and new combustion technology to stably control the NOx emission below 30mg/Nm3 without FGR. With the intelligent control system, it can adjust the combustion according to changes in working conditions to effectively reduce the energy consumption for users, ylw liquid phase chain grate horizontal coal fired heat transfer fluid furnace factory.

The high-precision processing boiler parts brought by digitization are the quality assurance of boiler welding and assembly. ZOZEN Boiler introduces 600 pieces of advanced CNC and digital equipment, including high-speed CNC surface drilling machine, CNC drum drilling machine, 3D laser cutting machine, 4-axis CNC tube bending machine, Φ168 CNC cubic tube bending equipment, 100mm three-roller CNC universal plate rolling machine, serpentine tube production line, CNC coil production line, membrane wall production line and so on. Currently, ZOZEN’s CNC cutting rate has reached 80% and above.

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 information era, only two-way communication and an open mind can maintain long-term development. Only by constantly understanding the market, improving the technology, and updating product and service concepts can we maintain the common development and progress with the times. Facing new opportunities in the new era, ZOZEN Boiler firmly believes that products, services and management will accelerate its pace in a more international, professional and humanized direction.
