Boiler description and superior advantages

1. Big corrugated furnace
Adopt the advanced corrugated furnace design, the combustion chamber with large volume. It enlarged the furnace diameter and create a bigger radiant heat exchange area, so increased the boiler thermal efficiency.
2.The boiler is equipped with world famous brand burners and valves groups such as Baltur, Riello, Weishaupt, Oilon etc. , 80% configuration, making the combustion more sufficient with lower failure rate.
3. thread smoke tube technology
Strengthen the heat transfer and reduce the number of smoke tubes and boiler shell size.Reduce the thermal stress at the tube end to prevent cracking of tube sheet.
4. Wet back structure
Wet-back smoke chamber, the whole smoke chamber is inside boiler proper, directly heating water in
boiler proper, greatly increase boiler heating efficiency. It can also lower the temperature of back tube sheet to prevent cracking. And also extend boiler life and reduce maintenance costs.
5.Three-pass exhausted gas flow design, ensure high temperature exhausted gas contacting with boiler tubes adequately, reduce exhausted gas temperature and increase boiler efficiency.
6.Automatic PLC control
Independently developed PLC control panel, better match our boiler operation. Siemens PLC with 10 inch touch screen and frequency transformer, more safety and easy operation.
