Air Curtain Burners produce virtually no smoke or particulates and can be used for burning most types of timber waste and debris such as stumps, whole timber, wood waste, forestry residue, demolition and waste stream timber. (Subject to Permit – where required). They are particularly suitable for processing timber that is highly contaminated with objects that would damage other processing machines, such as metal, stone, concrete and wire and on sites where a low environmental impact is required.

Currently, these types of site are very expensive to clear and can result in expensive tipping charges. With an Air Burner there is virtually nothing to remove from site. Wood waste is reduced by approximately 98% in volume to a fine inert ash. Metal and other contaminants can then easily be removed for recycling and the remaining material mixed in to the site soils or removed. They are also extremely quiet and virtually dust-free when operating.

PRINCIPLE OF OPERATION.  

High velocity air is directed across and downwards at an angle into a fire-box creating the “air curtain” or lid across the top of the fire and a rotational turbulence within. The rotational turbulence provides a super oxygen-enriched environment within the combustion area and accelerates the combustion process by raising the temperatures inside to approximately 1,832º F (approx. 1,000º C). This is many times hotter than a conventional open fire. The high velocity air curtain across the top traps unburned particulate and smoke inside, until it is almost completely consumed. The end result achieves nearly 100% combustion with minimal escaped particulate and smoke.
