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.
ZOZEN YLW series biomass-fired chain grate thermal oil heater is favored by Indonesian customers because it has the features of high temperature and low pressure, precise temperature control and high quality. Heater proper and chain grate are transferred separately. The video shows the heater proper is on the delivery. YLW series thermal oil heater adopts the square coil structure to realize high safety and sufficient heating surface.
ZOZEN DZL series biomass/coal-fired boiler has sufficient steam output. The boiler adopts the arched tube plates and threaded smoke tubes, which strengthen the heat transfer and solve the cracking problem of rear tube plates. Please kindly click the chat online to get more information.
In Sri Lanka, a set of ZOZEN 15 tph DZW series biomass-fired steam boiler was being installed and debugged. The user is a well-known local palm oil manufacturer, AEN PALM OIL PROCESSING (PVT) LTD. The boiler fuel is palm fiber. The boiler is a tri-drum boiler which has characteristics of no ash accumulation, high efficiency and good environmental protection performance. There is no need to stop the boiler for dust removal, which can make the boiler keep the normal operation for a long time. Meanwhile, considering the combustion characteristics of palm fiber, ZOZEN technicians also optimize the feeding hopper, furnace arch and air distribution device of the boiler to solve the coking problem caused by the fuel combustion.
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.
The new generation of SZL series boiler is cooperated with Shanghai Jiaotong University. It increases the furnace height, increases rotating speed, adds ash blowing device and designs ash removal system at the bottom of the grate. These well solve problems like scaling, abrasion, front arch, etc. It can also reduce the maintenance and operating costs and extend the service life of the biomass-fired boilers.
ZOZEN WNS series gas/oil-fired steam boilers have outstanding eco-friendly performance. The flue gas emission of WNS series gas/oil-fired steam boilers can meet the environmental protection standards. Facing the strict low NOx emission requirements across the country, ZOZEN Boiler realizes the low emission of NOx (less than 30mg/Nm3) via the advanced low-nitrogen burner and combustion technology. ZOZEN WNS 20 tph steam boilers are applied in the food, chemical and nonferrous metal industries.
ZOZEN SZL series biomass-fired boiler has the characteristics of sufficient output and high thermal efficiency. To ensure the sufficient combustion of fuel and save the fuel costs, ZOZEN analyzes the characteristics of different fuels, and optimizes the feeding hopper, width and length of grate, grate rotating speed, secondary air inlet place and direction. ZOZEN also adopts the design of separate air chambers and air dampers to ensure the complete combustion of different biomass fuels and improve the boiler thermal efficiency to above 88%.
