[Stoves] "stirring fan"

[Boll, Martin Dr.]

Dear all

-about vortex and gas-mix reflecting,

 

What do you think of a "stirring"-fan?

A fan which partly re-circulates the transported gasses?

This would allow good burning-gas/air mixture with least excess fresh air.
It could reach good mixing without jet-pressure of the fresh air.

That would be a fan, which makes turbulence, and brings as little fresh air
into the burning region, as desired.

 

I think of:

-A fan with fan-blades, which are each divided into two parts. The more
central parts blowing, while the more peripheral parts are sucking (-When
the fan rotates in the same direction). 

-Both parts are divided by a circular ring (-band). This ring does not allow
the directly flow from the inner to the outer part of the fan.

 

-Into the suction-side of the blowing fan-part reaches the fresh-air tube,
which can be regulated (closed or opened)

This regulates the amount of fresh air.

The fan-speed can be regulated, to allow different degrees of "stirring".
