How the G-Series Gasification Outdoor Furnace Works
Steel Tech Inc is proud of it's reputation of producing innovative outdoor heating meth-
ods and our G Series outdoor furnaces are continuing that trend. They operate more
efficiently with fewer emissions than other outdoor furnaces. The Heatmaster ss G Se-
ries wood furnaces use up to 50% less wood to create the same heat.
How It Works
°
200-300 F
Wood gas is generated in a high
temperature reaction (>700°) be-
tween the wood and a limited
amount of oxygen. The heat and
lack of oxygen "bakes" the wood,
causing the gases in the wood to
release in the form of carbon
monoxide, hydrogen and carbon
dioxide.
The wood gas mixture that is cre-
ated in the firebox then gets
forced through the base of the
fire along with any ash that would
come with it and burned at tem-
peratures around 2000° in the
gasification chamber. This cre-
ates a very hot, very clean burn
helping you get the most out of
your fuel. After the gas is
burned, heat is extracted to the
water jacket using the heat exchange tubes.
Normal exit temperatures of the exhaust are 200-300 F.
The most notable indicator of effective gasification is the lack of smoke exiting the
chimney. However, many times you will see white exhaust that dissipates quickly,
which is steam from the wood in the firebox.
The gasification process creates longer burn times and can reduce wood consumption
as much as 50% compared to a standard outdoor furnace..
