The Oven

Posted by

Here is the oven which is an option for any combustion system 6" or larger. In order to reach baking temperatures, it needs to sit near the heat riser. .

The groves are for adjustable shelves. The interior is 12" × 12".

Here is a quick video of its assembly.

The oven ships flat. The joints are filled with fireclay mortar as it is installed. A door frame and a door with glass is included in the price for the oven.

The Dragon Heater masonry oven was tested with a 6" combustion system in the stair castle build. It demonstrated:

  • Even Heating
  • Temperatures to 560°F
  • Ability to maintain a given temperature
  • Quick recovery after opening the door

This oven comes with a door and can be wired for a 12V light kit. It is also compatible with standard oven probes that go inside the meat or dish being cooked. It is 12" x 12" x 14".

Here is an image with the door:

Oven Temperature Profile

The chart to the left is starting the Dragon Heater cold. No more fuel was added to the heater once it appeared the temperature had stabilized at around 550-560°F. At this point, it is losing as much heat out the glass door as new heat is being added.

You can see two dips where the door was opened to see what effect there was on the temperature. As you can see the temperature drops more gradually than it increases. The dip on the way up was a lapse in fuel loading.

Maintaining a Stable Temperature

Next, we wanted to see if a partial loading of the heater would maintain a stable temperature. Once the temperature dropped to around 280F fuel was added. 1/3 to 1/4 of the feed tube was filled and the remainder of the tube was covered to prevent excess air. The results are shown below. As you can see it leveled out pretty nicely.

Operational Considerations

Sustaining Temperature at 280F

Like other wood fired ovens, it produces an even heat, with heat coming equally from all directions of the oven. There are no hot or cold spots.

Because the heat originates outside the oven it is called a white oven. A black oven is where a fire is lit inside the oven.
