PRINCIPLE OF AIR CURTAIN INCINERATION
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.
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 can ex-
ceed 1,800º F. These machines do not inject any fuels into the fire, the fire is sustained only by add-
ing 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.
1. Manifold and nozzles that create the air
curtain over the earthen pit (burn chamber).
2. Wall of earthen pit (30 ft. long, 8 ft. wide &
min. 8-10 ft. deep).
3. Clean wood waste to be burned.
4. High velocity air curtain.
5. Continued air flow over-oxygenates fire
keeping temperatures high.

T300 Air Curtain Trench Burner with HATZ 4H50 Diesel Engine & Fluid Coupling
OPERATING MANUAL
GENERAL DESCRIPTION OF T300
The T300 is a mobile air curtain burner which is used in combination with an earthen pit or trench
made to function as the combustion chamber. The T300 unit is a fully self-contained, trailer mounted
system that includes a power plant, fluid drive system (automatic clutch), blower fan, manifolds, car-
rier pipe and fuel tanks.
This unit does not require assembly on site, as the carrier pipe and manifolds deploy and unfold.
The Diesel engine drives a fan which produces high velocity air. This high velocity air is directed
down the carrier pipe to the manifold. The carrier pipe is an important safety element, as it gives the
machine the required “set-back” from the fire. This set-back will help protect the machine, if the fire
gets too high or if the wind changes direction.
Once in the manifold, the air is evenly distributed across the burning trench through the manifold
nozzles. Air is directed across the top and down into the combustion zone. The curtain of air acts as
a top over the pit, trapping particulates (PM or small airborne particles) and adding oxygen to the
combustion zone, thereby generating a hotter more complete fire.
Temperature achieved by this unit while burning clean wood and other vegetative waste can range
between 1,000º F and 1,800º F.
The air flow coupled with the recommended dimensions of the pit creates an after-burner effect. By
re-circulating the air under the curtain, residence time of the particulates is increased long enough
for their effective combustion with very little smoke escaping.

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 machine’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 curtain 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 reducing 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 pit causing larger
sized particles to be ejected from the pit. Besides violating the EPA limits for PM (particulate
matter) the larger hotter embers ejected will pose a much greater fire hazard.

OPERATING MANUAL
(Vers. 08.08.2023)
T300 Air Curtain Trench Burner with HATZ 4H50 Diesel Engine & Fluid Coupling
OPERATING MANUAL
The Air Curtain Burner operator is dealing with fire on a daily basis; it is very important that each
and every individual involved with the machine be aware of and practice very rigid safety precau-
tions.
When you are running the machine, you are responsible for assuring that it is operated in the safest
possible manner at all times. During the burning operations there may not be any signs of smoke
from the trench, but small hot embers will always be coming out. These embers rise up on the hot
gases from the fire. Operators must be aware of the area around the unit to insure “spot fires” do not
ignite. If you notice something wrong, correct it immediately, and if you cannot correct it, find some-
one who can and/or shut down the machine.
The T300 is very safe as long as it is used and operated in the manner for which it was designed;
however, it will be no safer than an open fire burning above ground when it is not being used and
operated properly.
Basic Safety Points:
1. Personnel should not enter the pit while building it.
There is always the danger of the pit collapsing. Personnel must not enter the pit. The pit should
be secured and marked to prevent anyone from falling in.
2. Once the pit is in use the area should be restricted.
The area around the pit should be controlled by the trained operators. If the pit is to be re-used
the next day, then a security guard and secure fencing should be used around the pit to insure
no animals or persons will fall in. If the pit is not to be reused then the fire should be extinguished
and the pit filled in with dirt. The operators must monitor the activities around the pit at all times.
3. The Machine must only be operated with the cowling closed and secured.
The top cowling provides a guard for the drive belts and fan inlet. There is a risk of serious injury,
if the machine is run with the cowling open.
SAFETY CONSIDERATIONS
READ ALL SECTIONS OF THIS MANUAL BEFORE YOU BEGIN BURNING OPERATIONS
DANGER: Falling into the fire pit will cause serious injury or death.
DANGER: Watch for DANGER NOTICES throughout this manual.

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.
4. The Machine should be placed on cleared, level ground.
The placement or positioning of the machine on the job site can be very important. The machine
should be placed in a manner to give the greatest clearance on the downwind side of the pit. The
unit should be placed on level ground to facilitate proper positioning of the manifold alongside the
pit.
5. The Machine should be placed such that no combustible material is within a minimum of
100 foot clearance in any direction.
The machine should not be located over combustibles, such as dry grass, brush or peat moss. In
addition, hot embers will escape from the pit and, depending on the wind, will land on the ground
around the unit. The unit should not be located within 100 ft. of any combustible material.
The waste material to be burned during the day’s operation can be staged within the 100 ft. pe-
rimeter 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 ft. perimeter or in accordance with the chart below which suggests adjust-
ments for wind speed.

6. The Machine should not be operated when the wind speeds reach 20 MPH.
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 on Page 5 regarding the suggested set back.
7. NEVER use highly combustible materials to light the pit.
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 pit 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, Diesel fuel oil is an acceptable option.
8. Shut the unit down in an emergency.
Stop loading the pit, stop the air flow by shutting down the engine. Dump dirt, sand or water into
the fire pit.
9. Personal Safety (Personal Protective Equipment - PPE)
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 ft. 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. Opera-
tors should never wear synthetic material (i.e. poly-
ester) 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 100% 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. 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 such
as respirators.

1. Once the machine is in the correct location, first chock
the wheels with suitable blocks or wedges to keep the
trailer from moving, disconnect your tow vehicle. Next,
remove the two jacks from the storage box under the
top cowling and fit them to the jack points at the rear
and front of the trailer. Using the three jack stands, lev-
el the trailer.
2. Lift the cowling of the machine and secure it with an
appropriate cowling support prop rod / device.
3. Check engine fluid levels, top up as necessary.
4. Check drive belts (see Page 29).
5. Check fan bearings for grease, regrease per mainte-
nance schedule.
6. Check engine for leaks, check for any loose compo-
nents and any obstructions at the fan inlet.
7. Close the top cowling and secure all latches (See Pho-
to on upper right). Lock “D” lift latch.

8. Use the 3 jack stands to set the trailer level.
9. Remove the carrier pipe locking bolt, use this bolt to
secure the manifold in step 12.
NOTE: When the T300 first arrives, the locking bolt
is replaced with a “travel bolt assembly” for flatbed
truck transport. Remove this device before first use
and replace it with the locking bolt shown here. You
will find it in a pouch in the “Black Binder” that con-
tains the Operating Manual (Shipped in the T300
toolbox).
10. Release the front winch and extend the carrier pipe
manually by pulling the grab handles. Do not use
any equipment or machinery to accomplish this.
11. Extend the carrier pipe completely until the yellow/
black arrow indicator shows full extension and you
reach a hard stop.
DANGER: IF THE TRAILER IS NOT SET LEVEL THEN THERE IS THE RISK THAT
THE CARRIER PIPE WILL EXTEND OUT OF CONTROL AS SOON AS THE LOCKING
BOLT IS REMOVED. THIS COULD CAUSE SERIOUS INJURY AND/OR DAMAGE TO
THE UNIT.
DANGER: THE REAR JACK STANDS MUST BE EXTENDED BEFORE PULLING THE
MANIFOLD OUT, OR THE MACHINE WILL TIP BACK AND YOU COULD BE SERIOUSLY
INJURED.

HOW TO BUILD A PIT
1. The pit needs to be constructed with straight vertical walls to the dimensions shown on Page 15.
2. With the manifold resting on the ground, mark the outline of the pit. Leave the trailer and mani-
fold in position, if possible as it will save time in relocating the trailer.
3. Excavate as close to the manifold without damaging it (see the photo on Page 15). This will give
you the proper manifold position to ensure that the manifold does not protrude over the edge
of the pit which may lead to excessive temperature build-up in the manifold which will cause
damage to the manifold.
You may also want to retract the manifold assembly about half way with the manifold sections in
travel position to assure that it is not suffering any damage during the pit excavation work. Once
the pit is built, PUSH and do not pull the assembly back. Pulling it would be too dangerous and
could easily result in an accidental fall into the pit. Next, swing out the manifold sections again,
making sure not to fall into the pit as that could cause serious injury or death. The manifold must
rest on the ground at the edge of the pit without hanging over it.
4. The ground under the machine needs to be as close to level as practical. If the ground slopes
down from the pit this will cause the air curtain to be too high and if the ground slopes up from
the pit this will cause the angle to be too low.
5. Construct a safety barrier on the loading side of the pit, for example, by securing a large tree
trunk there to prevent the loader from being accidentally driven into the pit. Such a calamity
could, of cause, result in serios injury or death.
6. After the pit has been used for several days, it may need some re-construction due to partial col-
lapse. After the pit becomes wider that 10 feet and the walls are less than vertical, the trench
burner will begin to lose its effectiveness and may start to emit more smoke (particulate matter)
than desired. At this point you should either repair the pit or relocate and construct a new pit.
DANGER: THE PIT SHOULD BE PROTECTED AT ALL TIMES BY USING A
SUITABLE FENCE, BARRIER OR ENCLOSURE TO PREVENT PERSONS OR
ANIMALS FROM FALLING INTO IT.
NOTE: IF YOU HAVE TO BUILD UP THE GRADE IT IS IMPORTANT THAT THE
FILL IS WELL COMPACTED, SUCH THAT A STABLE PIT MAY BE FORMED.
ON THE LOADING SIDE OF THE PIT OPPOSITE THE MANIFOLD SECURE A
SAFETY BARRIER, FOR EXAMPLE FROM A LARGE TREE TRUCK, TO KEEP
THE LOADER FROM BEING ACCIDENTALLY DRIVEN INTO THE PIT.
