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 9 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 main air 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 thermos-ceramic wall adding oxygen to the combustion zone helping to generate
a hotter more complete fire. This additional agitation helps prevent the fire from starv-
ing 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 re-
ducing the oxygen and further reducing combustion efficiency. The result is
that your through-put drops and smoke increases.
2) Increasing the air flow beyond design standards will over pressurize the Fire-
Box causing significantly more particles (embers) to be ejected from the Fire-
Box. Besides violating the EPA limits for PM (particulate matter) the larger
hotter embers ejected will pose a much greater fire hazard.
