Chain grate is a common mechanized combustion device, which is used in biomass-fired boilers, coal-fired boilers and thermal oil heaters. ZOZEN chain grate is designed and produced independently, with reasonable structure and exquisite material selection. According to different fuels, ZOZEN Boiler also designs different grate widths, lengths and air distribution systems to ensure stable ignition and full combustion of fuels.
During the assembly process of ZOZEN WNS gas-fired boiler, the workers will assemble the threaded smoke tube produced in batches one by one according to the specifications. Then, the professional welder completes the automatic welding of the tube sheet.
ZOZEN WNS oil-fired and gas-fired boiler is one of the best-selling series of energy-saving and environmental protection boilers in China. The inside of the boiler consists of large diameter corrugated boiler, threaded smoke tube, and other boiler components.
ZOZEN SZS series gas/oil-fired boiler adopts the PLC control system, it can automatically control the system by temperature, water level and pressure control. ZOZEN Boiler provides the advanced parts and auxiliaries with the boiler system.
ZOZEN SZS series gas-fired and oil-fired steam boiler has the advantages of high efficiency and energy saving. This series of boiler adopts double drum with full membrane structure. The SZS series boiler adopts flue gas backflip technology, with the economizer and condenser to improve the thermal efficiency to 98% and above.
ZOZEN DZL series biomass/coal-fired boiler has designed with multiple separate air chambers, which can realize the air distribution at different combustion. With the speed gear, the sufficient combustion of fuel can be ensured according to different combustion rate.
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.
