Hi everybody.
Well, an idea which passed through my mind.
I have a problem, with the fresh air cooling my second bell, after fire is out.
I was thinking, why not use perforated steel, between intake and exhaust, near the exhaust of the bell, with the total CSA of the holes, equivalent to the stystem CSA. But the friction on all the edges, would tremendously increase the drag, hence reducing the draft somewhat. Forcing the bell to stratificate a smidge more, because of the jet of gases would be less strong, and would wash the bell less.
Just an idea.

Hi Satamax! 1) About fresh air cooling your second bell, can you say how it succeds to enter the stove and the bell? Have you no possibility to close the in and outs? (sorry maybe did you already explain this somewhere else?)
2) I have not yet an opinion about your idea with the perforated plate : I must think (I am not very quick!). But I suppose one should increase the total ISA, maybe of 50% otherwise it would be (I think )like closing a bit the damper (fermer le clapet de sortie), no?
3) Do you know that the french MHA (Association Française des Poeles Maçonnés Artisanaux : AFPMA) has its second meeting in june 2015, in Dordogne?

Intresting info Benoit. Where in Dordogne? I will need to make a door at some point, but for the moment, i have none. That's why i have "airwash"

I might have used a inappropriate word : I wanted to say a way to shut, to close the stove just before the stove pipe to prevent the stove to cool because of ait passing through. I often forget english words that I understand when I read them but when I write in english it is a different story!
