Max Combustion from flame swirling and windscreen shape

Post by SSGHawk » Wed Apr 16, 2014 9:51 pm

Is here any agreement that the bottom of the windscreen must not be vertical but must have a shape like the Caldera cone?
This come from an old test thread from zelph about 2007. This distance between the incoming air and the flame allows the flame to swirl and have better combustion.

Experiences and thought ladies and gents?
regards to all

It has always been known that the amount of holes in the base of a windscreen must match or exceed the output of the stove while burning. The windscreen placement is kept at a distance only enough to allow the given amount of air to pass upwards. Get it too close and not enough air will pass between the pot allowing for an efficient amount of oxygen to enter at the base of the windscreen.

The only advantage of the cone style is that it supports the pot in a more stable manner. Down side of the cone is it can be used for only one size pot. If that matters :roll:

One pot exactly.
It seems that if I use your kmart port windscreen stand as the basic model but have it sized with snaps at two different places for two different pot sizes it will be a more useful "Two-Fer". IT would be nice to have a two-fer that would work for one of your Fosters and for a Kmart pot.
Thanks again

Yes, I think a cone made to fit a kmart pot will be able to be sqeezed shut enough to fit a foster can...I think!!! not sure ....need to try it. I have some screens for kmart pots. Next time I go the garage and remember....hahaahaha the remembering is the key to that action :lol: remember to test it for multi fit . ;)

I tried it today!!!! :DB: :DP: :DB: :DP:

It will work for a Kmart grease pot and a foster can pot.

The screen has to be marked for holes while in the Foster can mode or clamp it tight and then punch the holes while it's in the rolled up position if you can picture what I'm describing :mrgreen:
