OPERATING MANUAL
PRINCIPLE OF AIR CURTAIN INCINERATION
OPERATION
Air curtain incinerators are designed primarily as a pollution control device. Using a diesel engine
driven fan, these machines generate a curtain of air with a very particular mass flow and velocity.
This curtain of air acts as a trap over the top of an earthen trench or thermal-ceramic lined firebox
(burn chamber). The wood debris is dumped into the trench or firebox and then ignited (usually with
a propane torch or with a small amount of diesel fuel) just as you would light any other pile of wood
you intended to burn. Once the fire has gained strength the air curtain is turned on.
The air curtain traps most of the smoke particles and causes them to reburn under the air curtain
where the temperatures may exceed 1,800º F. These machines do not inject any fuels into the fire,
the fire is sustained only by adding more wood waste. The air from the air curtain is not heated. The
only fuel used in the continuous operation is that of the diesel engine driven fan.

OPERATING MANUAL
GENERAL DESCRIPTION S-SERIES
The self-contained refractory walled air curtain system is manufactured as an over-the-road trans-
portable combustion system designed to reduce clean wood waste and vegetative growth to ash in
a safe, controlled burning process without excessive particulate emissions. The FireBox is open to
the ground, except for the Roll-off versions; they have a floor to accommodate the roll-off rail sys-
tem. The standard S-Series machines are offered in several sizes. The smallest is the S116 (16 ft.
firebox) and the largest is the S330 (30 ft. firebox).
The T26 CharBoss is a trailer-mounted street-legal Biochar processor designed do optimize pro-
duction of high-grade Biochar. The self-propelled T28 TrackBoss is similar to the T24 BurnBoss,
however, with the trailer frame replaced by a remotely controlled track system.

OPERATING MANUAL
GENERAL DESCRIPTION S-SERIES
When delivered to a job site, the S-Series machine is ready for use as soon as it is off-loaded. The
entire system is built on a skid type base frame which is designed for easy movement over the
earthen ground. The forward equipment deck supports a four cylinder diesel engine, a 58 gallon fuel
tank, the direct drive system and the air fan. When viewed from the front of the unit, the patented air
disbursement manifold is mounted on the left top side of the firebox (combustion chamber). The fire-
box is lined with proprietary thermal-ceramic refractory panels. The panels are cured prior to installa-
tion at the factory to drive out any moisture to ensure they are stable at first use in the field. The
back of the firebox is fitted with refractory lined doors that allow ash removal and access to the fire-
box (only when it is empty).
The diesel engine is coupled through a fluid drive (automatic clutch) that turns the air fan. The high
velocity air is sent down the manifold through the vanes and directed to the outlet nozzles. A bal-
anced and distributed air flow is directed across the top of the firebox and then reflected down into
the combustion zone.
The curtain of air acts as a top over the firebox (burn chamber) trapping a large percentage of the
escaping particulate matter (smoke) and causing it to burn down even further under the curtain be-
fore finally escaping through the curtain as a hot gas. The air from the nozzles travels across the
firebox creating the air curtain effect, then it reflects off the far side thermal-ceramic wall, adding oxy-
gen to the combustion zone helping to generate a hotter more complete fire. This additional agitation
helps prevent the fire from starving for oxygen as the ash builds up during burning operations.
All of this is carefully engineered to provide the correct amount of air at the correct
velocity. It is sometimes thought that more air flow will actually increase the burn
rate. This is INCORRECT. Modifying the air flow will actually have the opposite
effect and reduce the machine’s through-put. Additionally, it will reduce the ma-
chine’s ability to meet air quality minimum standards. There is a maximum rate at
which wood can burn. Trying to exceed that rate by adding more air to an air cur-
tain burner causes two major problems:
1. It will cool the fire reducing combustion efficiency creating more smoke (carbon
dioxide and nitrogen enriched). This will begin a circular effect of further reduc-
ing the oxygen and further reducing combustion efficiency. The result is your
through-put drops and smoke increases.
2. Increasing the air flow beyond design standards will over pressurize the firebox
causing larger sized particles to be ejected from the firebox. Besides violating
the EPA limits for PM (particulate matter) the larger, hotter embers ejected will
pose a much greater fire hazard.

IMPORTANT:
Notice how dirt is placed all around the inside bottom rails to close any openings under
the skids that may be the result of uneven earthen terrain? This will prevent smoke
from escaping. The FireBox must be placed on well-leveled soil (dirt), never on surfac-
es like concrete slabs, gravel, crushed stones or asphalt.

SAFETY CONSIDERATIONS
READ ALL SECTIONS OF THIS MANUAL BEFORE YOU BEGIN BURNING OPERATIONS
The S-Series machine operator is dealing with fire on a daily basis; it is very important that each
and every individual involved with the machine be alert and practice very rigid safety precautions.
When you are running the FireBox, you are responsible for assuring that it is operated in the safest
possible manner at all times. If you notice something wrong, correct it immediately. If you cannot
correct it, find someone who can and/or shut down the machine.
Basic Safety Points:
1. The unit must be placed on cleared, level ground.
The unit should be placed on level ground directly on the soil surface to facilitate loading,
dumping and moving of the unit. The rear doors weigh approximately 2,000 lb. each and should
not be opened if the unit is inclined on any axis more than 5 degrees.
2. The unit should be placed such that no combustible material is within a minimum 100 ft. clear-
ance in any direction and never on a concrete pad or gravel stones.
The S-Series units do not have a bottom and must not be located over combustibles such as
dry grass or peat moss which may cause a fire to spread to other areas. It is equally important
not to place the FireBox on anything other than earthen soil, never on a concrete pad, on grav-
el or crushed stones. There is a good reason for this warning. Concrete or gravel can contain
water which the heat in an operating firebox could vaporize quicker than it can be drawn out.
This could result in increased vapor pressure that can cause the concrete or stones to explode.
Fragments could possibly fly out of the firebox and cause injury or death to persons nearby.
In addition hot embers will escape from the firebox and, depending on the wind, will land on the
ground around the unit. The unit should not be located within 100 ft. of any stored combustible
materials. The waste material to be burned during the day’s operation can be staged within the
100 ft. perimeter to facilitate loading. The operator must monitor the loading pile to ensure em-
bers do not ignite the loading pile. The combustible materials to be stored for burning at a later
date must be stored outside the 100 ft. perimeter or in accordance with the chart on page 6 of
this manual which suggests adjustments for wind speed.
3. The unit should not be operated when the wind speeds reach 20 MPH as the potential to carry
hot embers is significantly increased.
As an operator you should always be aware of wind speed and direction. increased wind speed
will affect the integrity of the “air curtain” and will cause hot embers to travel farther. See the
wind speed chart regarding suggested set back on page 6.
WARNING:
Watch for and pay attention to the danger notices throughout this manual.

(Vers.10.26.2023)

OPERATING MANUAL
4. NEVER use highly combustible materials to light the unit.
Highly combustible materials such as gasoline, refined spirits, etc. ignite at an explosive rate
which may cause serious injury or death. The safest method to start the fire in the firebox is to
use materials such as paper and kindling wood. In the absence of these materials or when start-
ing materials with a high moisture content use diesel fuel oil as an acceptable option.
5. NEVER climb on the unit to view or light the fire.
Use the ladder built into the unit and never go beyond the top step, or use a step ladder or simi-
lar platform located at a safe distance from the unit. Do not stand along the rails or on top of the
S-Series unit under any circumstance.
6. Shut the unit down in an emergency.
Stop loading the unit, stop the air flow by shutting down the engine. Dump dirt or sand on to the
fire. Water should only be used as a last resort, as it will likely damage the refractory panels.
DANGER: The above distances serve as a GUIDELINE ONLY! You MUST ALWAYS
observe the down range area regardless of the wind speed.
You must always observe local fire ordinances and directives from the local fire depart-
ment or other competent authorities.
DANGER: Falling into the FireBox will cause serious injury or death.

DANGER: You must ensure debris does not build up on the front equip-
ment deck. It must be keep clean at all times during operation to prevent a
fire that would damage or destroy the engine and accessories.
7. Personal Safety (Personal Protective Equipment – PPE)
Operators must be aware of the following potential hazards:
a. Flying hot embers being released from the fire. Operators or anyone within the 100 ft. radius of
the fire should wear appropriate fire resistant clothing. The ideal outerwear for an operator
would include a Nomex jacket, leather gloves, eye protection, hard hat, cotton work jeans and
steel toe boots. Operators should never wear synthetic material (i.e., polyester) around the fire
as this type of material can melt and cause injury. Additionally, some synthetic materials will
support combustion and could be very dangerous around fire. One hundred percent cotton
materials would be the minimum, cotton treated with a fire retardant would be better and fire
proof materials like Nomex would be best.
b. Noise: Ear protection is recommended around the BurnBoss. It is a good practice to wear ap-
proved ear protection when working in close proximity to the fan and engine.
c. Hot Panels: The backs of the thermo-ceramic panels and parts of the steel structure can each
temperatures as high as 500ºF. Caution should be taken to ensure operator and visitors do not
come in contact with these hot areas.
d. Ash and dust can be released during the operation and during cleaning. Operators should
wear appropriate breathing masks (PPE, such as respirators) to protect themselves from inhal-
ing the dust and ash.

OPERATING MANUAL
HOW TO SET UP THE FIREBOX
A. POSITIONING THE UNIT
The S-Series units are totally self-contained and ready to use upon delivery to the job site. The S-
Series units are built on a skid base that is designed to facilitate dragging the unit into position and
to move the unit around the site. The weights of the various units are given in the table on page 2.
Ensure that lifting or tow cables are certified for these weights.
With respect to the prevailing wind direction, the unit should be positioned such that the wind comes
over the back of the manifold. This is the preferred position. It is also acceptable to have the wind
blow into the manifold. It is discouraged, however, to have the wind come from either end of the ma-
chine, as this will tend to disrupt the air curtain.
As highlighted under Safety Considerations on page 5, the FireBox must be placed on plain level
ground (dirt), and it must not be placed on combustibles like dry grass or peatmoss and also never
on a concrete pad, gravel, crushed stones or asphalt.
DANGER:
When you tow (drag) the FireBox, especially in soft soil, watch that the dirt does not
build up under the panels and lift the panels off the rails. That is why you must never
walk inside the firebox when it is being towed. A dislodged panel may fall on a person
inside the firebox which may cause serious injury or death.
Typically, the softer soils will require a longer cable. If the rear of the unit sinks into soft
soil while it is being towed, use another vehicle to follow and carry some of the load. If
you are still having trouble dragging the unit, try a different length of tow cable. Always
stay clear of the tow cable while the dragging operation is underway and wear Personal
Protective Gear (PPE).
B. PRE-OPERATION CHECKS:
1. Air filter for cleanliness (VERY IMPORTANT).
2. Engine oil level.
3. Engine coolant level and antifreeze rating.
4. Diesel fuel level.

OPERATING MANUAL
SITE PREPARATION
THE GOALS TO GOOD SITE PREPARATION ARE:
To place the FireBox for easy access.
To sort the waste wood pile.
To organize the inflow of new wood waste.
When locating the FireBox, consider access for your truck and trailer to load and unload the Fire-
Box. Ensure there is enough room to maneuver your truck and trailer.
Consider where the waste piles will be located. We generally recommend two waste piles
(explained in the next section).
Consider the predominate wind direction. Hot embers will be escaping from the FireBox during all
burning operations.
Consider where and how you will empty the firebox. If you are going to ‘drag’ the FireBox to empty
it, ensure there is room and the soil conditions are not too soft. If you are going to excavate the ash
out, then consider where you will dump it. In most cases cold ash can be reapplied to the land.
Check your local ordinances.
Once the FireBox is in position, it is important to place dirt around the inside bottom of the firebox
(burn chamber) to close any openings under the skids that may be caused by uneven terrain as
shown on page 4. This will prevent smoke and heat from escaping. Pay particular attention to the
seal for the forward (engine deck side) wall. Any openings under the panels or forward skid will al-
low heat from the fire to reach the area below the engine deck. This could cause the engine deck to
become hot enough to burn the paint and be a hazard to someone standing on the deck.
DANGER: This machine DOES NOT prevent hot embers from escaping. This machine
is designed primarily as a pollution control device to reduce the smoke generated from
burning clean wood waste.
DANGER: Never dig a pit in the center of the firebox. This will make it hard to seal the inside of the
firebox and the walls of the pit can deteriorate during operation allowing smoke and heat to es-
cape from the firebox or reach the area below the engine deck creating a hazard for anyone
standing on the deck. This will void your Air Burners Factory Warranty.
DANGER: Never place the FireBox on combustibles like peat moss or dry grass, and
never position it on a concrete pad, gravel or crushed stones or asphalt.

SITE PREPARATION
Faster operation through staging the wood piles
Air Burners FireBoxes were designed primarily as a pollution control device, but operated correctly
they will burn clean wood significantly faster than open burning. To achieve the best throughput, the
fire must remain at the highest temperature possible. You achieve this by remembering three rules:
1. Don’t smother the fire with a huge load or a load of very dense material.
2. Load “less more often” smaller bucket loads more often.
3. Sort out a pile of your best burnable wood, use it to create a hot fire.
The basic principle of operation is not too dif-
ferent from a campfire. You use your best
wood to get it started, and if the fire dies
down you add some more “Good Wood” to
bring it back up. The big difference is that on
your campfire you are probably not adding
root balls, leaves or pine needles. These are
the high moisture content and dense materi-
als that bring the fire temperature down.
The temperature drops (smoke increases)
and your burn rate slows down, if you over-
load the machine with materials that have
high moisture content, such as tree branches
with leaves and needles, or green branches
such as palm fronds. While these are certain-
ly ok to burn in the firebox, you want to add
them to a hot fire so they dry out and ignite quickly.
To keep the temperature up and to maintain the highest throughput of waste, you should mix the
very burnable wood with the less burnable materials throughout the course of the burning operation.
The most common way to accomplish this is to stage a pile of the most burnable materials or what
we call the “two pile system.”
“If it’s burning clean it’s burning hot; if there is smoke, you’re losing money.”

OPERATING MANUAL
SITE PREPARATION
The “Two Pile System”
For an efficient operation you would have two piles:
The first pile or “Main Debris” Pile, is the material being generated from the land clearing or forest
clearing operation and is located away from the ember path, but with good access to your loading
machinery.
The second pile or “Good Wood” pile is your best and most burnable wood. When you first setup
the site, the operator should spend some time sorting through the main debris pile pulling out what
appears to be your best, most burnable materials. This is the material with which you will start the
fire and this material will give you a good hot burning base fire. You will also draw from the “good
wood” pile throughout the day if you should need to stoke up the fire (more on this in the following
sections).
As the FireBox operator is drawing from the main debris pile throughout the day, he or she should
continue to replenish the “good wood” pile as necessary. The “good wood” pile only needs to be
enough material to stoke-up the fire if needed and enough material to get you started the next day.
DANGER:
You must ensure debris does not build up on the equipment front deck. It
must be kept clean at all times during operation to prevent a fire that would
damage or destroy the engine and accessories.
IMPORTANT WARNING ABOUT BURNING OF PALLETS
Wooden Pallets, especially spent pallets, burn extremely hot. DO NOT load
the FireBox above approximately 3/4 of the height of the burn chamber.
Heat damage to the manifold and other structure may occur which would
not be covered under your Limited Factory Warranty.

LOADING THE FIREBOX
You can load the FireBox from either side, but we recom-
mend loading from the manifold side because
(1) it is safest and (2) it tends to increase the life of the
manifold, as it is reduces the chance for it to be acci-
dentally damaged.
THE GOALS IN STARTING AN S-SERIES UNIT
ARE:
1. To achieve an even fire across the length of the firebox.
2. To start the fire from the bottom of the initial pile.
3. To build a hot base fire.
There are two methods for lighting the unit; a cold start and a hot start. A cold start means the Fire-
Box is clean and has no hot coals left from a previous burn. A hot start uses heat from the coals of
the previous day’s burn.
COLD START
Unit should be on level ground and the engine should be off, as the fluid clutch would spin the air
fan which would make it more difficult to light the fire and the fire may even be blown out. Ensure,
though that you have started the engine and warmed it up before switching it off for the light up.
To prevent smoke from escaping under the firebox, shovel dirt along the inside bottom edges of the
panels. It will only need a couple inches to prevent the smoke from escaping underneath the unit.
This is generally only a concern on hard ground, and it usually only lasts for the first hour of burn-
ing. As burning continues the ash will build up and seal off the bottom of the firebox as well.
Load your most burnable material (materials from the “Good Wood” pile as discussed in the previ-
ous section) which is the smaller, dryer and cleaner wood, into the firebox to a level about half way
up. Ensure that the entire bottom area of the firebox (burn chamber) is covered. If you are using
diesel fuel to assist in the lighting, spray it (approximately 10 gal.) across the top of this first load of
wood. Be sure to get some diesel fuel on the wood near the lighting holes in the FireBox side and
on the wood towards the back. This will help make it easier to light.
DANGER: If you are using an accelerant, first ensure there are NO HOT COALS
remaining in the FireBox.
DANGER: DO NOT use highly volatile accelerants such as gasoline or kerosene, to
light the fire. These fluids ignite almost explosively and may cause injury or death.

LOADING AND STARTING THE FIREBOX
Overview
Once you have the smaller material loaded and your accelerant added (if used), load some larg-
er, heavier feedstock on top such as logs or big branches. Load these heavier materials (also
from your “good wood” pile) to a height just below the manifold nozzles or approximately ¾ height
for machines burning pallets. This heavier material will help compress the smaller material which
will give you a better light-off. If there are large air spaces between the wood debris in the firebox
the heat will not build up as quickly and the fire may be more difficult to light.
Once burning, this material will become your hot base fire to support continued burning. Use your
best and driest materials (“good wood”) for startup as this will form a strong base for continued
burning, plus it will start quicker and burn hotter. If you will be burning stumps, it is best to load
them after the first hour of burning when the fire is up to full temperature.
The level of material in the firebox for light-off should be kept just below the manifold nozzles, ex-
cept for units burning pallets which should only be loaded up to approximately ¾ of the firebox
height. Pallets burn extremely hot and loading them to a higher level would tend to warp or de-
stroy the manifold. This heat damage would not be covered by your Limited Factory Warranty.
If you are using diesel fuel as an igniter, it is sometimes helpful to add a second coat to the top
load again. ENSURE THERE ARE NO HOT COALS REMAINING IN THE UNIT before adding
the accelerant.
Your goal is to develop a good hot base fire and to maintain a good hot fire throughout your burn-
ing operation. This will give you the cleanest burn and the most throughput.
There is always smoke on start-up as all of the material in the firebox contains moisture, com-
pared to later in the burn operation when only the new material you are loading contains mois-
ture. Plus, the air curtain cannot be fully engaged until the fire has strengthened, or you run the
risk of blowing out the fire.
DANGER:
NEVER stand on the machine as you may fall in causing serious
injury or death.
IMPORTANT WARNING ABOUT BURNING OF PALLETS
Wooden Pallets, especially spent pallets, burn extremely hot. DO NOT load
the FireBox above approximately 3/4 of the height of the burn chamber.
Heat damage to the manifold and other structure may occur which would
not be covered under your Limited Factory Warranty.
