Looks a bit complex with all the electric add-ons. What about when the battery goes flat?

Sweet. Any video of the stove burning?

Looks a bit complex with all the electric add-ons. What about when the battery goes flat? This is something I built from stuff I had lying around. The original burner I used was built from the Champion TLud plans It works fine but does not have enough output to heat my 22 inch wok or grill very well and did not have a long enough burn time. It was naturally drafted. So I put together the burner in the picture. So now it really cooks! I used two computer fans. The bottom one blows air through the bottom of the reactor and has a draft control gate to control output of the burner. The top fan blows air in through holes in the top of the reactor for secondary combustion of gases. It actually works quite well. It is able to be adjusted from a tall flame to fairly low flame. Not all that much differently than controlling the output on a gas grill. The fans run quite few hours on that battery. The battery is out of a commercial zero turn lawn mower and is a little smaller than a small car battery. If you don't like the battery you can connect to any 12 volt source like your car or small transformer. |

I find this type of grill has some advantages over other type of grills. Number one, wood fuel contains quite a bit of moisture. The meat cooks up very moist and tender. even without any food in the grill it will condense moisture on your hand if you put it in front of the exhaust. Can use found fuel from property. It makes a high quality charcoal that can be used for other purposes or even in your charcoal grill.
I do have some plans for an improved model. This design should be very easy to improve upon. It should be fairly simple to use one fan or blower. With the fan driven burner it does not need the pipe that is pictured in between the burner and grill body (this was used to improve draft in the natural draft system). The top of the burner should go right in the bottom of the grill body. On the current design, I have seen the temperature as high as 900 degrees Fahrenheit! This of course leads to a huge loss of btus and makes a burn hazard. The thing is too heavy. No good way to seal the burner to snuff out the charcoal. There are no handles on the burner. And that not even mentioning the grill body.
I think I will stick to the forced draft idea for now because it is easier to get good output and reliability out of. However it would be interesting to come up with a naturally drafted one that had high output. I am thinking that it would have to have a chimney of some sort. Any ideas or suggestions?
