Product Detailed
1:oil/gas fired 2:three-return fuel oil (gas) boiler 3:with the wave-type boiler inner and transfers radiation heat

WNS series horizontal internal-combustion furnace is pan-shell type horizontal three-return fuel oil (gas) boiler developed by absorbing domestic, foreign advanced technology and experience. It runs automatically. After the burner atomizes fuel, the produced torch is full of the wave-type boiler inner and transfers radiation heat through inner wall. This is the first return. The high-temperature smoke gas produced during burning accumulates in burning room and turns to the second return (screw smoke pipe bundle area).

After conversion heat change,  smoke gas's temperature reduces gradually and then it goes into the front smoke case; And turns into the third return (light pipe bundle area); Finally, it flows into chimney through rear smoke case.


1) After checked and accepted eligibly, the boiler can leave factory integrally for installation, debug and use easily.

2)It runs automatically. Burning, water level, temperature and steam pressure are adjusted and protected automatically.

3) The mobile front and rear smoke case is convenient to repair and keep boiler.

4)The international first-class burner guarantees thermal efficiency and improves integral quality.

5)Enough steam storage house and heating surface makes the boiler produce high-power, high-quality steam.

6) Water-cooling room is designed integrally to improve thermal efficiency and prolong boiler's use life.

7) Various high-quality boiler fittings guarantee boiler works in normal.

8) Wave-type hearth and large burning room make it have good thermal flexibility.

This series smoke boiler can improve boiler's efficiency, save fuel, reduce cost greatly to reach the aim of high-performance, oil (gas)-saving, safe boiler.
