MICRO-GASIFICATION
Fuel is added from hopper onto fuel pile above grate.
Fuel is top lit with lighter fluid.
Air enters upward through fuel.
Hot smoke fills the “smoke maker” above the fuel.
Air enters the “smoke burner” for clean combustion.
Used fuel becomes hot char and keeps the in-coming
raw fuel heated to release smoke (pyrolysis gases).
Openings for lower secondary air help control draft.
Ash and excess char are released after build up.

1.
The Chip Energy Biomass Grill
literally
“burns the smoke,” but smoke will not burn if it is
too cool, is deprived of sufficient air mixing, or contains excessive moisture. Because there are
so many variables (fuel types, fuel moisture content, wind, thinner air at higher elevations, over-
filling or under-filling of the fuel, air controls,
etc
.), you should experiment to fully learn how to
operate the gasifier and combustor. With some practice, you will master and appreciate the art of
cooking with biomass gasification.
2.
During extended burning times, the Biomass Grill will change over from TLUD gasification
to AVUD technology, a variation of traditional updraft gasification that consumes existing
charcoal at the bottom and creates more charcoal from the new fuel entering at the top. With
AVUD technology, the Biomass Grill can be operated continually because only a small amount
of ash accumulates at the bottom.
