[Stoves] High tech Pelmondo TLUD outdoors stove

[Roberto Poehlmann]

Hi to all,
i found this very interesting outdoors stove from Pelmondo.
Is a very high tech TLUD stove:

The interesting part of the stove, is the technology used that i don't have
seen before in any TLUD stove.

It has a mobile fuel chamber, that goes down when loading with pellets.
This fuel chamber move inside of another fixed chamber or cylinder, which
has the secondary air holes. Then, when the pellet start the burning, the
fuel chamber starts to rise slowly only by the action of the less weight of
the pellets.
The secondary air holes are triangular, so when the fuel chamber is fully
loaded, the secondary air holes are at maximun aperture. When the fuel
chamber is at the top, the secondary air holes are at minimum aperture or
closed (maybe).
This is ideal for the gasification stage, that require less secondary air.

For the primary air, i don´t know if the amount of primary air varies
depending on the position of the inner fuel chamber or not.

And the las thing i see in the video, is the shape of the inner chamber. It
has a space at the whole diameter of the chamber , that star at the bottom
and end a few centimeters below the top.
I think it serves por primary and secondary air at the same time, similar
to inner cylinder design of other TLUD stoves.

I bet that the transition to the gasification stage from the pyrolisis
stage are smoke free.
This stove are made for a completly free user operation, and whithout smoke
in the whole process to the end of the combustion.

Greetings!

Atte.
