BurnBoss® T24 Air Curtain Burner (Kubota Z482-E4 Engine)
OPERATING MANUAL
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 throughput. 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 that
your throughput drops and smoke increases.
2) Increasing the air flow beyond design standards will over pressurize the firebox
causing significantly more particles (embers) 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.
GENERAL DESCRIPTION OF BURNBOSS
The BurnBoss is a proven design that adds mobility to the Air Burners FireBox line of
machines. 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 fire-
box to be raised and lowered for easy movement over the ground. The forward equip-
ment deck under the cowling supports a two cylinder diesel engine, a 10 gallon fuel
tank, the direct drive system and the air fan. In addition the battery, firebox hydraulic
controls are located here. When viewed from the front of the unit, the patented air dis-
bursement manifold is mounted on the left top side of the combustion chamber.
The diesel engine is directly coupled to the air fan. The high velocity air is sent down
the manifold through the vanes and directed to the outlet nozzles. A balanced and dis-
tributed 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, 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.
