Air Curtain Burner
An Air Curtain Burner works by pushing high velocity air over the top of the
burn chamber, creating a curtain of air which the rising smoke cannot penetrate.
The unburned particulates are pushed back down into the chamber where they
reburn until they are light enough to rise through the air curtain.
Air Curtain Burners or Air Curtain
Incinerators are used to dispose of
forest waste generated from fuels
reduction projects in areas where
the debris cannot be left on-site, and
broadcast or pile burning is not an
option. Air Curtain Burners produce
a much cleaner, nearly smokeless
burn with emissions consisting mostly
of water vapor and biogenic carbon
dioxide.
guidelines. Because Air Curtain Burners
consume fuel so efficiently, they can
be operated on days when weather
conditions aren’t suitable for broadcast
or pile burning. Air Curtain Burners are
capable of burning five to seven tons of
material per hour.
The air curtain reduces particulate
matter (PM), or smoke, which results
from burning clean wood waste, to
an acceptable limit per United States
