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 INCOR-
RECT. Modifying the air flow will actually have the opposite effect and reduce the machine’s
throughput. 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 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 S-Series FireBox line of ma-
chines. When delivered to a job site, the machine is ready for use as soon as it is off-loaded. The
firebox system (burn chamber) is built on a patented trailer frame that allows the firebox to be raised
and lowered for easy movement over the ground. The forward equipment 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 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.
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 distributed air flow is directed
across the top of the firebox (burn chamber) 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 particu-
late matter (smoke) and causing it to burn down even further under the curtain before finally escap-
ing through the curtain as a hot gas. The air from the nozzles travels across the firebox creating the
air curtain effect, then it reflects off the far side thermal-ceramic wall adding oxygen to the combus-
tion 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.
