Introduction: Camping Stove
This my "prototype" about a camping stove for the outdoor cooking contest.
Material is stainless 316, but it can be made mild steel too.
Idea is that fire warms the air between the sides, that makes air to rise convectively trough the holes to the upper "flue gas chamber".
In the middle of chamber is a block that shares the chamber to two parts, making "cone" shapes for the both sides of the chamber.
That increases the speed of burning flue gas, that speed makes a negative pressure above the holes, and pulls more air to the flame from the holes.
There's also airholes in the "centerblock" for that same purpose.
Basic idea is similar than it is on the two stroke carburetor.
In this case Air= flame Fuel= air.
This was just for testing the idea. Actual products that im goin to make,
are round, and there's double walls all around it.
But i tought that one can get something for this " experiment " too.
Drawing shows the idea, and the video actual making and testing.
Step 1: Bottom and the Chamber
From the bottom you can see where the cold air goes in,
and after warming it rises up, and goes through the holes to feed the flame.
Flue gas burning chamber can be seen from two other pictures.
Step 2: Air Adjustment...
Simple air adjustment, with burning wood its in upper position.
When flame embers its in the lower position and gives heat longer.
Thanks for watching.
