I was bored to death with hard and slow starting, smokeback on windy days etc!
When i cut a restaurant fridge for it's stainless, i recuperated the fan in it. Which had melted a wire inside. Repaired this. It' IP65 or 66, so i thought, why not. Made a bracket, and voila, power asist draft. Ok, not pure rocket, but once the draft is strong and the last elbow is hot, i can turn it off. Mind you, i haven't tried it in strong southern wind yet. Ill report back then.
This green machine seems it will never work right. I've started it up today, with the fan, and i had a smidge of smoke. After a while, with roaring fire, and the fan on, it shouldn't smoke anymore! And it's smoke, not steam, i can smell it.
Or is my air drawing cooling the fire. Nevertheless, when i thought it was hot enough, i switched the fan off; and it was smoking like a box stove.
Firebox is insulated. Nearly with the right dimensions. i have a P channel, not drawing much, but it's there. I have a door with an opening that i can reduce. usualy open between 7 an 8cm, x7cm height. So 49 to 52cm², compared to the 201 of the 16cm riser. That's a bit more than the advised 20% oppening. So what is wrong?
Ok fuel might be less than optimal. But it's not at 20% moisture. Usualy sticks offcuts from woodworking. Actualy the wood in there today has spent most of the summer in the tipper of my truck. I haven't been able for a while, to get the back of the firebox to glow. Ok it's not that cold outside, around the 10C° for the moment. But it should work ok! It has worked all right in the past, where i could see only a haze. Nothing has changed since. I plan on enlarging the transition area, tho it's not that far off. I have a projection of at least 235cm². 15cmx5cm gap at the nearest, tho i have 8cm on the radius of the barrel. So it should be a bit more.
It's not a funny feeling, having to work with sub optimal parameters, like the crappy chimney. Restriction through the wall etc. And i can't move yet, the sale being blocked by the other part's liquidator.
Max, If there isn't enough draft you will have to open the primary air to get a complete burn. When I first made my batch box it worked fine. Once I connected it to my bench it slowed down a bit and I had to play with the door opening. After plenty of trials I felt concerned enough to notify to forum with this post which Peter placed in the library.
Have you cleaned it recently? Sounds like your system parameters are pretty tight, perhaps there is a bit of buildup somewhere throw in you off that is noticeable in warmer weather. Another thought I had was that perhaps the good draw of the fan is giving enough draft to overload the afterburner with hydrocarbons that can't be consumed. Still, though, if the balance between primary and secondary air is right it would seem that even an assisted draft should have the right proportions. So back to grizbach's thoughts, I guess...

daniel: in my experience as I am working now on something of that nature, I have thought of making a heat exchanger and distributing the heat through vents using a slower fan. Now after a few years I realize that mass heaters give out primarily radiant heat, for

vesuvius: Do any of you have experience with using the glass from home oven doors on a rocket stove? I'd like to have a viewing port on my stove but don't want to fork out for new ceramic glass. Any thought as to whether it would take the heat of a rocket stove?
