Food Factory Using Oil Fired Hot Water Boiler Working High Efficiency
Specification of WNS hot water boiler :
1. 59 years experience in manufacturing and designing
2. Easy maintenance, Very safety
3. ISO and CE
4. Working steady
5. Easily adjustment
6. Enough Steam Pressure
7. High thermal efficiency
8. Fuel adaptable
9. Easy to install
Special Design Features of WNS hot water boiler:
1. The spiral furnace design
Increase the overall strength of the furnace,make compensation for the heat exchange and shrinkage automatically,avoid the in-perfection of welded sew crack due to the change of tube plate heating stress.Therefore,boiler has strong adaptability about various of fuel,for example,heavy oil,light oil,natural gas,city gas.
2. Improve heat transfer technology
Apply the technology of heat transfer from “the light of Harbin institute”.Adopt the design of efficient heat transfer screw thread pipe and optimize the smoke speed.The output and heat efficiency of boiler don’t decrease with the extend of operation time,thus achieve a compact structure with 10% overload capacity.
3. Research PCL control board independently
Strontg conpatibility,PLC intelligent touch screen equipmet,10-inch touch screen,fool-type operation,safe and reliable,automatic ignition/flame-out/fire switch,high fired gas,low pressure protection,gas leakage protection,filling and stopping pump automatically,high and low water warning,ultra low water-level interlock,alarm when the temperature of smoke exhaust is too high and stop furnace operating.
4. Large load imported burner configuration
80% configuration ratio,light load drive,enough thermal energy import,guaranteed output,reduce equipment use fatigue,extend the service life,the quality of inlet valve group is steady and reliable.
5. Wet back built-in transfer smoke room structure design:all wet back structure,reduce the temperature of the tube plate,prevent cracking.
6. “the light of boiler institute”spirally corrugated pipe technology patent:Technology source of the light of Beijing boiler research institute are, raise smoke flow rate,raise heat transfer coefficient,strengthen heat transfer effect
