Outdoor bakeoven Originally posted by "really nice"
I'm glad I didn't get one for inside the house as occaisionally, the smoke comes out the front rather than the chimney. Guess I should have been a boy scout.
There are a few reasons why your outdoor oven will smoke on occasion-
The first is that being outdoors, you do not have a pressure differential that you would have were it located indoors. Pressure differential is one thing that creates draft.
Another reason is starting a fire in the traditional manner of lots of paper and small pieces of wood on the bottom, and large pieces on top. The fire starts burning very fast, and smoky, and when you try to stuff all that heat and smoke up a cold chimney/stovepipe, often it is too much, and it flows out the door instead. (not so much a problem if the oven is still hot from previous use the day before) The alternative is starting your fire useing what we call the top-down burn. You build your starter fire by stacking your wood with the bigger pieces on the bottom, and adding smaller pieces on top of each layer, finishing the top with small kindeling, and lighting the top. The fire starts a bit slower, but it will develop it own draft as it burns to the bottom of the pile of wood, and you will never have smoke out the door again.
BTW, the top down burn also reduces the amount of unburned wood (smoke) released into the atmosphere. Start up is often the dirtiest phase of a wood fire, any wood fire, in a bakeoven, masonry heater, open fireplace, or woodstove. |
