FAQ SECTION C
OPERATING AN AIR BURNER

Will you train and certify our operators on the use of Air Burners' equipment, and if so, at what expense?

Yes, we have field technicians who specialize in training and operator certification. There is a per diem charge for this service, and, additionally, the client pays travel and related expenses for the technician. Usually, three days are scheduled for the training, including travel time.

Can I burn chips or mulch that I have piled up and that now nobody wants? Taking them to the landfill will cost me a fortune, and the Fire Marshal wants me to get rid of them fast as they are a fire hazard or they may go septic and endanger the water table.

No. Chips and mulch are too dense to burn in the air curtain machines; they will smolder and create too much smoke for the air curtain to contain. It is important to understand that there is absolutely no need or better, it is counter-productive and must not be done, to grind or chip the wood waste before it can be combusted in the air curtain burner. The air curtain burner can handle root balls with rocks and dirt embedded, wet foliage, freshly cut or trees pulled freshly from the ground, whole logs (to the extend that they fit into the FireBox) or wet floating debris fetched out of waterways or from ocean shore lines; the grinder can do none of this.

Moreover, chipping and grinding is a very expensive method to the disposal of wood waste when compared to our air curtain burners. The equipment is very maintenance intensive and costly to operate and to acquire. Unless there is an application for beneficial reuse of the grindings, a much more environmentally friendly alternative is the use of an Air Burners system. Wood waste is reduced 96% to 98% to a sterile ash that can be land applied or used as a soil amendment. This process is considered "carbon neutral" by the EPA.

The chipped or ground wood waste has to be trucked to landfills at great expense for trucking and tipping fees. Take a look at this comparison of ACB disposal vs. chipping for land clearing or pallet wood waste disposal HERE.

How do I use a trench burner where the water table is high and it's difficult to maintain a pit?

First of all, it would be best to use a FireBox, but if you must use your trench burner, build a hill or berm from good, if possible, clay-like material on the surface and then dig a pit into the hill, staying above the groundwater table. The T-400/300/200 units must be placed on a dirt platform level with the top of the berm. The retractable carrier pipe cannot be positioned at an angle as it is rigid. It is important to position the machine such that the manifold will provide a properly angled air curtain over the pit. The T-350 has a flexible section of the carrier pipe and it can be positioned on ground level with the carrier pipe leading uphill to the pit.

How long does it take for the unit to cool off after use before the engine and fan can be cut?

Usually, about 1-2 hours.

How long does it take to set up a trench burner?

It takes one operator only about 3-5 minutes to set up the T-200, T-300 or T-400 without the need to employ ancillary equipment. This does not include the time it takes to dig the trench. The T-350 will require a set-up time of 30-40 minutes.

How long will the trench burner last?

Many Air Burners trench burners are still in service after more than 30 years. We have been manufacturing our traditional T-Series trench burners for more than 30 years.

Is there any reason why I should not make my trench as deep as I can?

No (but within reason, say up to 12 to 13 feet), some additional depth will give you a little more volume. Consult the spec sheets for pit dimensions. A few jurisdictions have rules in place that limit the pit depth.
