Horizontal Oil Fired Boiler (WNS)

Typical Type: Down-Flow, Fully Wet Back, Three-Pass Shell Boiler
1. Oil(Gas)Fired Steam Boiler is of the type three-pass with wet back and central back-flame in the series steam output more than 1T/H, flame tubes are symmetrical on furnace axis, uniform distribution is good to improve the stress of the Tube plates, fully wet back structure combustion chamber inundates water completely so cooling conditions is good and back tube plates will not be scoured by the high-temp smoke, so the boiler running conditions and durability can be improved.
2. The application of corrugated furnace, not only increase the heating area but also lessened the damnification to burning chamber because of expansion on heating and contracting on cooling, Big volume furnace leads to completely burning and can save fuel.
3. Front flame box fit by gemel, which can bring much convenience to open. After it is opened the furnace and flame tubes can be approached to clean and maintain. What's more, big volume furnace design can reduce the temperature of front flame box to avoid being damaged.
4. Big steam space reduces the speed of the steam separating from the surface of the water. The inner water separator set can insure high quality steam output.
5. Blow down automatically: The blow down valve is controlled according to the concentration of boiler, it will be opened when concentration reach to the blow down values, normally, it will be closed. (The acts above will run automatically when the boiler is stopping) so it can save labor more and lessen the waste of water and fuel, slower the form of fur-scale efficiently in the boiler, and extend the life of boiler.
6. Package construction and main auxiliary pre-assembled considerably reduce installation costs.
7. Boiler can be operated completely by just using the fingers to press keys in the intelligentize digital control system
8. Perfect protection: Over-pressure switch on interlocking protection device, controllers giving alarms, burner stopped, and blow down automatically with safety valves opening.
9. Convenient maintenance: There is an access on top of the boiler for cleaning and maintenance if it's needed.
10. All of the boilers are tested with rated load in order to ensure the performance and reliability of burner, automatical controlling apparatus and rated security units.
(0.8Mpa and smaller series with function of automatically blow down and fur-scale detecting)

TThe control system provides functions such as automatic running, manual running, timing-set running, failure logging and password protectionT

1. Operated with function of timing-set, the system can turn into on duty or off duty automatically. Control system can set three groups timing period in 24 hours. The system will turn into on duty when present time is in any stage of three groups, and touch screen will display the same as automatic mode while the timing is in a on duty stage. It is a off duty stage beyond a on duty atate. Each timing period includes a turn on time (Hour, minute) and a turn off time (Hour, minute). The hour and minute of the three group timing stages and current time can be set and reset. The user can set varying temperature range at varying time.
2. Failure logging: When a failure occurs, the touch screen will give an alarm simultaneously and record the reason and time of this failure. The controller can record the latest 5 failures forever for further query.
3. Passwort protection: You can set a password for the controller to prevent others change the operation parameters unconsciously while may bring an abnormal running. You can select to turn on password protection (password protection is available) or turn off password protection (password protection is not available).
