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 thermo-ceramic lined firebox. 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)
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 re-burn 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 sus-
tained 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
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 ground. The forward equipment deck supports a four cylinder die-
sel engine, a 58 gallon fuel tank, the direct drive system and the fan. When viewed
from the front of the unit, the patented air disbursement manifold is mounted on the left
top side of the combustion chamber. The back of the FireBox is fitted with refractory
lined doors that allow ash removal and access to the (only when it is empty) firebox.
The diesel engine is coupled through a clutch drive PTO (Power Take-Off) that turns
the fan. The high velocity air is sent down the manifold through the vanes and directed
to the outlet nozzles. A balanced and distributed air flow is directed across the top of
the box and then reflected down into the combustion zone.
The curtain of air acts as a top over the fire box, trapping a large percentage of the es-
caping particulate matter (smoke) and causing it to burn down even further under the
curtain before finally escaping through the curtain as a hot gas. The air from the noz-
zles travels across the FireBox creating the air curtain effect, then it reflects off the far
side thermo-ceramic wall, adding oxygen 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 Fire-
Box causing larger sized particles to be ejected from the firebox. Besides vio-
lating the EPA limits for PM (particulate matter) the larger, hotter embers eject-
ed will pose a much greater fire hazard.

OPERATING MANUAL
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 rig-
id safety precautions.
When you are running the S-Series unit, you are responsible for assuring that it is op-
erated in the safest possible manner at all times. If you notice something wrong, cor-
rect it immediately. If you cannot correct it, find someone who can and/or shut down
the machine.
Basic Safety Points:
1) The unit should be placed on cleared, level ground.
The unit should be placed on level ground to facilitate loading, dumping and
moving of the unit. The rear doors weigh approximately 2,000 lbs. 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 foot clearance in any direction.
The S-Series units do not have a bottom and should not be located over com-
bustibles such as dry grass or peat moss. In addition hot embers will escape
from the unit and, depending on the wind, will land on the ground around the
unit. The unit should not be located within 100 feet of any stored combustible
materials. The waste material to be burned during the day’s operation can be
staged within the 100 foot perimeter to facilitate loading. The operator must
monitor the loading pile to insure embers do not ignite the loading pile. The
combustible materials to be stored for burning at a later date must be stored
outside the 100 foot 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.
DANGER:
Watch for the danger notices throughout this manual.

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 box is to use materials such as paper and kindling wood. In
the absence of these materials or when starting 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 similar 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 either disengaging the PTO or 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 department or other authorities.
DANGER: Falling into the FireBox will cause serious injury or death.

7) Personal Safety
Operators need to be aware of the following potential hazards:
A) Flying hot embers being released from the fire. Operators or anyone within
the 100 foot radius of the fire should wear appropriate fire resistant clothing. The
ideal outwear 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 ma-
terial can melt and cause injury. Additionally, some synthetic materials will sup-
port 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 machines. It is a
good practice to wear approved 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 reach temperatures as high as 500ºF. Caution should be tak-
en to insure 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 to protect themselves from
inhaling the dust and ash.
DANGER: You must insure debris does not build up on the equipment
front deck. It must be keep clean at all times during operation to prevent a
fire that would damage or destroy the engine and accessories.

OPERATING MANUAL
HOW TO SET UP THE MACHINE
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 General Description section. 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 machine, as this will tend to disrupt the air cur-
tain.
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
DANGER: When you tow (drag) the S-Series units, especially in soft
soil, watch that the dirt does not build up under the panels and lift the
panels off the rails. Never walk inside the box when it is being towed.
Typically, the softer soils will require a longer cable. If the rear of the
unit sinks in soft soil while it is being towed, use another vehicle to fol-
low 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.

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 firebox. 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 next section).
Consider the predominate wind direction. Hot embers will be escaping from the Fire-
Box during all burning operations.
Consider where and how you will empty the firebox. If you are going to ‘drag’ the Fire-
Box 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 box is in position, it is important to place dirt around the inside bottom of the
FireBox 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 side) wall. Any openings under the panels
or forward skid will allow 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.
Never dig a pit in the center of the firebox. This will make it hard to seal the inside of
the box and the walls of the pit can deteriorate during operation allowing smoke and
heat to escape from the FireBox or reach the area below the engine deck creating a
hazard for anyone standing on the deck and will void the Air Burners Warranty.

OPERATING MANUAL
SITE PREPARATION
Faster operation through staging the wood piles
Air Burners Fireboxes were designed primarily as a pollution control device, but oper-
ated correctly they will burn clean wood two or three times faster than open burning.
To achieve the best throughput, the fire must remain at the highest temperature possi-
ble. 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 different 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 and
leaves and pine needles. These are
the high moisture content and
dense materials 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 branch-
es with leaves and needles, or green branches such as palm fronds. While these are
certainly 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 sys-
tem.”
“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 clear-
ing 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 de-
bris 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 burn-
ing 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
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 insure 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.
