[Stoves] Smoke-free biomass pellet fueled stove

[Inversiones Falcon]

Paul, something similar I´ve desingned about 2 years ago, my problem is that I don´t have to much money for invetigation I have a model at the factory and on prototipe allready workin as you can see in the pictures.

Dear Ronal and Prof. Nurhuda,

I too await the answers to Ron's questions.   And add a comment
      about what Ron wrote:

you appear to be pre-heating both primary and secondary air - can you attribute any performance improvement to that?  (I know of no-one else doing both)
I cannot think of anyone preheating primary air in a TLUD to any significant degree.  That is because there is no serious heat in the lower areas of TLUDs until the pyrolysis front makes it at least half way down the column of fuel.  And then the heat is by conduction through the metal sidewalls.   

Looking at the video by Nurhuda, I do not detect any effort to
      pre-heat the primary air.   He can clarify that for us.   What is
      important is the quality of the control of the amount of primary
      air that can enter.   VERY  WELL DONE.   His stove should be a
      case study of industrial manufacturing of natural draft TLUDs.

I request from Prof. Nurhuda as much additional information as
      possible.   The more that everyone and the GACC knows about the
      Indonesia TLUD success story, the more opportunities there will be
      for the further scaling up to serve people in Indonesia and
      elsewhere.

        intrigues me most is that you are controlling secondary air for
        the pyrolysis gases.  And apparently doing it (and primary air)
        well with the rotating disc mechanism.  I do not recall seeing
        any other stove controlling both (without a fan) - so any data
        on the value of that for users of the stove could be very
        helpful to others.  (Can they control excess air by the look of
        the flame?)
