It is more powerful BECAUSE it consumes more wood.

Yes that's what I wanted to say
thanks

Hi Inspired by this post: linkI thought I'd try the broken riser. seems to start with a little more smoke than the configuration of the first video, and a burn may be less clean, but here I also shortened the combustion tunnel perhaps this may be the cause. The heater part with more force (but more smoke), the flame was immediately sucked into the combustion tunnel. I would like to try then the P-channel and trip wire. |

Wow.. Ok, that broken riser thing is just weird..

Sorry Donkey , you mean that it is built in a strange way ?In fact I would like to perform further experiments for the kitchen

No.. I think you've done it the way (or close enough) that Matt has described it.
It's just weird for ME, after years of looking at straight, vertical heat risers..
I'm intrigued but sceptical.

Independentenergy, once insulated, you should have better burns. All thoses exposed firebricks are a heatsink.

Max, I compared the same combustion units with broken riser and vertical riser in the same conditions, I noticed that the broken riser smoke more.
Then isolating obviously improve, but the vertical riser will improve in the same way.
Would serve a thorough study to properly drive the gas within the combustion chambers.

Yes, I do not have much experience , but the inclined position of the riser does not seem natural , I noticed that the back of the riser tilted warms more than the rest ( obviously. .. ) the heat tends to go up ... a trip wire to drive the heat would be ideal . The stove part well in ignition , but then seems to slow down , the fire becomes less vigorous . I measured T output from the riser angle of about 250 ° C, compared , at 400 ° C with the vertical riser of the same wood seasoning. I do not know if the test is reliable , would need a serious experimentation .. |

I wonder how these temps would compare - all other things being equal - to vortex's (semi?) widening sloping riser? Might the gasses be happier if they have more freedom to expand sooner across the sloped surface? A J-feed or batch box with 12" of vertical riser then widening to 12" across by 6" deep at 45 degrees slope?
