Hot Sale Fire Tube Diesel Heavy Oil Natural Gas Industrial Steam
WNS series gas and oil fired boiler is package type full automatic
horizontal three pass fire tube wet back structure boiler. The
boiler can produce hot water, saturated steam or superheated steam.
It’s adaptable for wide ranges of fuels such as natural gas, LPG,
biogas, methane gas, diesel heavy oil etc. The boiler has a large
corrugated furnace which have big radiate heating area and we
adopted threaded smoke tube which greatly increased the boiler heat
transfer efficiency. The boiler burners and valve groups are world
famous brand from Italy and German, quality is stable and reliable.

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
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
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.
