Silverfire Super Dragon Fan Stove
I've been experimenting with the Silverfire Super Dragon Fan Stove
for a couple of days. The first attempt resulted in crispy blackened bacon
; not the stoves fault, all me and hunger-induced impatience. I'll spare you the horror of wasted pork; the sooty ring around the wood feed shows how much heat there was in trial 1.
First lesson learned is the same lesson as for all the other rocket-stoves and heaters
tried thus far. More paper.
The next trial was far more successful. Once the fire had a steady flame it only took 12 minutes to boil water
. Managing the airflow via the electric fan requires keen observation and timing; which I have not yet mastered, thus it took about 30 minutes to get both fires going well. I predict that after 5+ uses one could get the fire going well in about 10 minutes.
Rocket mass stoves with L-shaped wood feeds require paper first, then kindling
, then larger pieces. The Silverfire stove is the opposite, paper on top. The paper should
be placed around the inner perimeter of the fire box rather than in the center. The picture above is an example how NOT to layer the paper. Lesson learned. Tossing it in haphazardly or in a centered pile and the fire won't catch the woody bits. Both times I used only sticks and twigs found nearby.
The fan adjustment was a little confusing at first. Basically low is left and high is all the way to the right. When first igniting the paper it worked best when my kettle covered the entire wood feed and the fan was on low. Once it sounded rockety, I slid the pot off the wood feed 0.5 cm and turned the fan on high. there needs to be some airflow between the pot and the 'burner,' but too much too soon and the paper goes out. It is not advised to cook a meal, such as bacon with the fan on high. Also important to remember is that when cooking with cast iron
it is best to remove the pan from the fire just before the food finishes cooking. Cast iron retains so much heat that dinner can go from perfect to charred pretty quickly. We don't have the Silverfire cast iron trivet, but flat rocks work just fine.
It was tempting to dismiss this device since it does require electricity. However, the fan can be run off a small solar-power system or a 12v plug. I am confident my Prius could run the fan with a 130w inverter and an extension cord.
The Silverfire Super Dragon Fan Stove will be available for use during the PDC and AT courses.
