An explanation of how this outdoor wood furnace works follows.

1. Wood is loaded into the firebox all the way to the top.

2. 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.

3. 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.

4. After this the 2000 degree exhaust enters the heat exchange area where the exhaust temperature is brought down to temperatures of under 300 degrees

5. 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.
