WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
1. Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.
2.Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
3. Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.
4. Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.

Wood is placed in the fire box and lit while the draft is flowing out through an exhaust hole in the top of the fire box. Once the wood has lit sufficiently, the exhaust hole is closed and the draft is forced down through slot in the fire brick, which is super heated by the fire.
Transcript: Gasification is simply the process of burning smoke. That process can be elaborate or it can be simplified. We use the simplified method, the elaborate method would be secondary air, downdraft, refractory brick all will give gasification but it’s basically getting the smoke to a high enough temperature for the smoke to ignite.
Wood Gasification Wood starts to gasify at around 750 degrees F. Primary air is delivered to the top loading chamber in a regulated way so as to maintain an oxygen starved region. In the top chamber the wood gas is essentialy baked from the wood. This wood-gas is forced downward through a refractory nozzle where pre-heated secondary air is combined.
Vigas gasification boilers. Vigas make log gasifying boilers with outputs from 25-80kW and efficiencies in excess of 80%. The Vigas uses one fan to supply combustion air to burn the wood gases and to regulate the output of the boiler. Visit our Vigas gasification boilers page, or click on the picture for more details
The capstone project for the class will be designing a system and getting it reviewed by John. The class is capped at 50 students, and there are 30 discount seats. When properly applied, wood gasification boilers allow dry firewood to be converted into thermal energy at efficiencies far higher than those of non-gasification type wood
WOOD GASIFICATION BOILERS: Wood is a convenient source of energy, which can be harvested when needed and is easily stored. If you have your own seasoned timber with low moisture, then what better, more efficient, way to put it to good use than for heating your home with a wood gasification boiler.
Wood Gasification vs. Complete Combustion. The result of the wood gasification process is woodgas, which in gasification wood boilers don’t just go up and out the chimney (peculiar for standard wood boilers), but is rather emitted, superheated and mixed with air, with further resulting in complete combustion (leaves little or no ash).
Oct 23, 2014· Here’s an introduction into what’s involved with the installation and use of a Log Gasification System.
Gasification is a process that converts organic- or fossil fuel-based carbonaceous materials into carbon monoxide, hydrogen and carbon dioxide.This is achieved by reacting the material at high temperatures (>700 °C), without combustion, with a controlled amount of oxygen and/or steam.The resulting gas mixture is called syngas (from synthesis gas) or producer gas and is itself a fuel.

The Attack gasification boiler uses this method, however when there is a large amount of return water from a buffer tank or heating system the boiler is continually cooled with cold water every time the pump goes on. To prevent this a boiler temperature maintenance thermostatic valve is used.
