[Stoves] the 150 gasifier in operation in Vietnam

[Crispin Pemberton-Pigott]

Dear Paul

 

I think it is not necessary and there are two reasons. First, that energy is
not being lost. It is inside the system and sooner or later it comes out in
the form of a hot gas, probably preheating the gas before the flame. Second,
aluminum would melt in there. If you radiated it at the dome from below the
dome would only get a little hotter and you would be cooling the system
somewhere else.

 

If the heat was getting away from the stove completely that would matter.

 

Regards

Crispin,

You've seen the video of the dome that is red hot.

The dome emits radiant energy in all directions.
I placed a shield on the sides of the dome to stop the lateral loss of
radiant energy.
You can see the shield clearly in the video.

But there is a lot of radiant energy (perhaps half) that goes down to burner
and does not heat the pot.
I want to put a piece of tin foil about 4 mm above the burner.
If it does not touch the burner, it should be more reflective.
The idea is to reflect radiant energy back up in the direction of the pot.
Does this make sense?
What difference should this make?

Paul
