market you have came to the right place.

We are still waiting for the EPA to review the test of our E3400
Gasification Outdoor Wood Furnace in order to get our orange sticker but if
you would like to review the test results

Advantages of the E3400
1.
Much less Emissions.
Tested by Intertec laboratories using the EPA owhh test procedure and
results shown to be .32 lbs per MBTU of wood burned. This compares to old
style furnaces that average 1.8 lbs per MBTU of wood burned.
2.
Much less smoke then
old style furnaces. Also any exhaust you will smell will not be the acidic
smell that the old style furnaces produce.
3.
Uses less wood for the
same amount of heat, 20-50% less than most other models on the market. This
means if you use 20 loads of wood a year with the old style furnaces you
will only use 10-15 loads with an E3400.
4.
No creosote in the
exhaust stream. Used properly these furnaces will not produce creosote in
the chimneys or heat exchange area.
5.
No creosote means no
chance of chimney fires. You can add additional chimney without the worry of
coming out to your furnace and having a big fire streaming into the air.
6.
No sparks. The long
travel path and extreme cooling of the exhaust means no sparks coming out of
the chimney. This greatly
reduces the chance of a fire around the stove.
7.
Lockable doors with
keys. Keep the kids, mother in law, or other unwanted individuals from
gaining access to the stove or controls.
8.
Easy to read water
level indicator. Water level is indicated by a float mounted on the top of
the furnace. Can be seen from 100 yards away if you need to add water.
9.
Easy cleanout. Stove is
cleaned by the use of a ash pan\ash scoop once a week. No need to turn some
auger or burn your coat arms shoveling ash out of the feed door.
10.
Clean design. Stove
does not become smoke covered like other models on the market. It is
designed to not show smoke in area that it may come out of.
In addition there is not creosote running down the chimney so you do
not get a roof covered in creosote or ash.
An explanation of how this outdoor wood furnace works
follows.
-
Wood is loaded into the firebox all the way to the
top.
-
Air is injected using a forced draft blower from the
rear of the furnace. The outdoor wood furnace is designed such that
there is no way for the air to escape except to go down though spaces in
the firebrick in the bottom of the outdoor wood furnace. This causes the
fire and smoke to get very turbulent in the firebox and mixed very well
with an excessive amount of oxygen.
-
The exhaust exits through openings in the bottom of
the outdoor wood furnace floor made of heavy duty firebrick. It then
separates into 2 separate exhaust streams and travels through an
insulated maze of firebrick tunnels over 12 feet long. it is forced to
change direction many times and gets adequate time to burn all of the
gases and to drop out much of the fine emissions. This area gets
very hot, sometimes in excess of 2000 degrees.
-
After this the 2000 degree exhaust enters the heat
exchange area where the exhaust temperature is brought down to
temperatures of under 300 degrees
-
After exiting the the heat exchangers it then travels
another 6 feet and then exits the chimney pipe on the top of the outdoor
wood furnace.
