T-400 Air Curtain Trench Burner with Kubota V3600-TE Engine
OPERATING MANUAL
GENERAL DESCRIPTION T-400 SERIES
The T-400 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 T-400 unit is a fully self
-contained, trailer mounted system that includes a power plant, mechanical drive sys-
tem, blower fan, manifolds, carrier 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 im-
portant 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 (small air-born
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 vegetative waste can
range between 1,600 and 2,000 degrees Fahrenheit.
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 particu-
lates is increased long enough for their effective combustion with very little smoke es-
caping.
