PRINCIPLE OF AIR CURTAIN INCINERATION
OPERATION
Air curtain burners are designed primarily as a pollution control device to make open pile burning
cleanest. Using a diesel engine driven fan, these machines generate a curtain of air with a very par-
ticular mass flow and velocity. This curtain of air acts as a trap over the top of a thermal ceramic
lined firebox like the CharBoss. The wood debris is dumped into the firebox (burn chamber) and then
ignited (usually with a propane torch and 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 directly under the
air curtain where the temperatures exceed 1800º F. These machines do not inject any fuels into the
fire, the fire is sustained only by adding more wood debris. 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.
The same air curtain pollution control principle is also built into the CharBoss, however, it has been
designed with special features to process the wood waste into biochar rather than completely elimi-
nating it by burning it into residual ashes. Biochar is a byproduct in the residuals of all our air curtain
burners and it has become a very desirable natural product. The simple to operate trailer-mounted
CharBoss processes forest slash or other clean wood waste into commercially viable quantities of
biochar. It is ideally suited for on-site operation in forests i.e., for fuels management.

GENERAL DESCRIPTION OF THE CharBoss
The CharBoss design is intended to allow for the use of our self-contained refractory walled air cur-
tain system design, but mounted on a trailer frame for ease of mobility and biochar processing in-
stead of total wood waste elimination. The standard S-Series machines are offered in several sizes
as indicated below. Most of the functions and principles for the CharBoss are the same as the stand-
ard FireBox, except for the design features that process wood waste into biochar. The T24 Burn-
Boss is similar to the T26 CharBoss, except it has been designed strictly for the efficient reduction of
wood waste and not for enhanced biochar processing. 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 OF CharBoss
The CharBoss is a design that adds not only mobility but biochar processing to the Air Burners Fire-
Box line of machines, in particular to the popular T24 BurnBoss. When delivered to a job site, the
machine is ready for use as soon as it is off-loaded. The firebox system is built on a patented trailer
frame that allows the firebox to be raised and lowered for easy movement over the ground. The for-
ward equipment deck under the cowling supports a three-cylinder diesel engine, a 20-gallon fuel
tank, the direct drive system and the air fan. In addition the battery and firebox hydraulic controls
are located here. When viewed from the rear of the unit, the patented air disbursement manifold is
mounted on the right top side of the combustion chamber of the firebox.
The diesel engine is directly coupled to the main air fan. The high velocity air is sent down the man-
ifold through the vanes and directed to the outlet nozzles. A balanced and distributed air flow is di-
rected 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, trapping a large percentage of the escaping partic-
ulate matter (smoke) and causing it to burn down even further under the curtain before finally es-
caping through the air curtain as a hot gas. The air from the nozzles travels across the firebox cre-
ating the air curtain effect, then it reflects off the far side thermal 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.
The CharBoss incorporates most of the same design features as the BurnBoss. The CharBoss,
however, includes a hydraulically driven mechanical grid and transport design to facilitate biochar
processing as opposed to optimizing the rapid reduction of woody debris featured by the BurnBoss.
That is accomplished by limiting the residence time of the burning char in the firebox. A shaking
panel agitates the woody waste material as it is being combusted. This forces small chunks of hot
embers to fall onto a continuously moving belt system, which in turn transports the hot glowing
particle chunks to the rear of the machine. They are then released into a collection tray filled with
quenching water.
The biochar as a finished product is periodically collected from the quenching tray. This is a manual
operation on the current T26 model. To conserve water which is a precious commodity in the forest
and agricultural fields, the CharBoss design features a system that conserves water with minor wa-
ter loss from evaporation.

SAFETY CONSIDERATIONS
READ ALL SECTIONS OF THIS MANUAL
BEFORE YOU BEGIN BURNING OPERATIONS
The 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 which in-
cludes the use of personal protective equipment (PPE).
When you are running the unit, you are responsible for assuring that it is operated in the safest pos-
sible manner at all times. If you notice something wrong, correct it immediately, and 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 to facilitate loading, biochar collection and moving
(relocating) of the trailer-mounted unit. The firebox must touch the ground on all sides or smoke
and embers will escape.
2) The unit should be placed such that no combustible material is stored within a minimum
100 foot clearance in any direction.
The CharBoss has no bottom to the firebox and should not be located over combustibles such
as dry grass or peat moss. In addition, hot embers will escape from the unit and, depending on
the wind, they 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 op-
eration can be staged within the 100 foot perimeter to facilitate loading. The operator must
monitor the loading pile to ensure embers do not ignite the loading pile. The combustible mate-
rials 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 7 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 and position the Char-
Boss accordingly. 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 7.
WARNING:
Watch for and read 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 a
propane torch with an appropriate lighting torch to reach into firebox. When starting materials
with a high moisture content, use diesel fuel oil as an acceptable option.
5) NEVER climb on the unit or lean over it to view or light the fire.
Always load and operate the machine from the MANIFOLD side. Hot embers will escape at a low
height opposite the manifold. The left side (opposite the manifold - see drawing on Page 12) of
the machine should be a restricted access area to prevent injury.
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 onto the
fire. Water should only be used as a very 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 competent authorities.
DANGER: Falling into the firebox will cause serious injury or death.
DO NOT stand within 20 feet of the firebox on the side opposite the manifold.

7) Personal Safety
Operators need to be aware of the following potential hazards:
A) Flying hot embers being released from the fire. Operators or any person within a 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 material can melt and cause injury. Additionally, some synthet-
ic 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 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 green structure
can reach temperatures as high as 500°F. Caution should be taken to ensure operator and
visitors do not come in contact with these hot areas.
D) Ash, dust and steam can be released during the CharBoss operation, char quenching
and during cleaning. Operators should wear appropriate breathing masks to protect them-
selves from inhaling the dust and fly ash.
DANGER: You must ensure combustible debris does not build up on the
equipment. It must be keep clean at all times during operation to prevent a
possible fire that would damage or destroy the engine and accessories.

HOW TO TRANSPORT THE CharBoss
A. Towing CharBoss T26 (Triple Axle Version)
The T26 CharBoss as street-legal “Trailer-Mounted
Machinery” is “Non-self-propelled Agricultural/
Forestry/Construction Equipment”. The CharBoss is
equipped with self-adjusting brakes. They are
properly adjusted at the Factory, but it is the opera-
tors responsibility to keep them adjusted by periodi-
cally backing up the CharBoss while applying the
brakes hard.
Towing the T26 model is like towing any other “heavy” trailer. It is important that the
frame rails are as level as possible when hooked to the truck. The T26 comes equipped with electric
brakes on all wheels. Be sure your truck has an appropriate “brake controller” that can handle a
maximum current draw for the brakes of approximately 25 amps. The T26 is also fitted with a break-
away system. Make sure the battery is charged, the breakaway safety cable and the pigtail with 7-
blade RC receptacle are properly connected to the towing vehicle, so that the brakes and lights will
function and the breakaway battery be charged. Be sure your hitch assembly is rated for the towing
weight of 17,500 lb. (7940 kg) and a tongue weight of 1,450 lb. (658 kg). Always maintain correct
tire pressure to prevent premature wear and blow outs (see tire decal). Familiarize yourself with all
state and local ordinances that apply to hauling a trailer of the weight of the CharBoss on public
roadways.
TOWING and TRUCK CONNECTION
1. The CharBoss lower trailer frame rail MUST be level to the ground front to rear when connected
to the towing vehicle.
2. The electrical “pigtail” connection must be correctly made. Check the electric brakes and break-
away system to make sure they operate properly.
3. The front jack stand must be up and secure.
4. Make sure the firebox travel safety pins in front and rear are properly in place and secured with
their hitch pins for towing (see Page 11).
5. The safety chains and breakaway cable must be properly connected to the towing vehicle.
6. Test the brakes before you drive away.
Frame Rails
DANGER: Do not transport CharBoss from burn site until all fire and
embers are extinguished. Trapped embers may not be easily visible.

13. Shovel dirt around the outside edges where the firebox contacts the ground to prevent heat
and smoke from leaking out, especially behind the tires.
14. Locate Catch Basin for Biochar output
15. Fill Catch Basin with water
Hydraulic Oil
If you are operating in cold weather you may need to warm the hydraulic oil before use. In most
cases running the engine briefly will generate enough heat. If you still have difficulties operating the
hydraulic system you will need to change the oil to a colder spec oil (lower viscosity).
The hydraulic system comes standard from the factory with Amsoil Synthetic Hydraulic Oil ISO32
(Amsoil P/N HVH05-EA). If your machine will operate in cold temperatures or remain outside for
long periods in cold temperatures you may need to use a synthetic hydraulic oil such as Amsoil P/N
HVG05-EA, ISO22

HOW TO SET UP THE MACHINE
A) POSITIONING THE UNIT
The CharBoss unit is self-contained and ready to use upon delivery to the job site.
1) The CharBoss must be setup on level ground.
2) The firebox is lowered to the ground using the hydraulic controls (see Page 13).
3) The bottom edges of the firebox must touch the ground to ensure smoke and embers will not
escape underneath the firebox walls. If necessary shovel some dirt against the walls from out-
side the firebox to seal the edges. This must be done prior to loading the firebox with feedstock.
Add dirt around the bottom behind the tires to help prevent any heat from damaging the tires.
4) 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 curtain.
5) The firebox will be loaded either by hand or by machine, like a Bobcat, always OVER THE MAN-
IFOLD. The firebox should not be loaded opposite the manifold as there are many hot embers in
this area making it dangerous for personnel.
6) Secure the area (use orange safety cones, signs, fencing, etc.) opposite the manifold (20’ x 20’
- see diagram below) and along the side of the machine to ensure persons do not get near the
hot fire or embers or the rear biochar chute and quenching Device.
DANGER: Load the machine over the manifold to prevent
hot embers from endangering personnel.

SITE PREPARATION
THE GOALS TO GOOD SITE PREPARATION ARE:
To place the CharBoss for easy access.
To sort the waste wood pile.
To organize the inflow of new wood waste.
When positioning the CharBoss:
1) Consider access for your delivery truck and trailer to load and unload the CharBoss, if not pulled
by a pickup truck to the location. Ensure there is enough room to maneuver your truck and
trailer.
2) Consider where the waste piles will be located. We generally recommend two waste piles
(explained in next section).
3) Consider the predominate wind direction. Hot embers will be escaping from the firebox during all
biochar processing operations.
4) Consider clearances for unit to be raised and towed forward until all the ash remains behind.
When emptying, the tires must not come in contact with the hot embers or they will be damaged.
5) Consider clearances to collect and temporarily store biochar collected from the quenching tray
and to clean the machine at the end of the workday.
6) Once the firebox is in position, it is important to place dirt around the outside bottom of the firebox
where the ceramic panels meet the ground to “seal” the bottom. This will prevent heat from escap-
ing. Pay particular attention to the seal between the tires and firebox and between the front wall
and engine bay.
DANGER: This machine DOES NOT prevent hot embers from escaping.
DANGER: Make sure you do not load foreign objects like metal rods or stakes.
They may get lodged into the firebox panels and conveyor system and cause
damage to the machine.
