windscreens

Some of the stovies will chime in here. The screens vary depending on what type of fuel system you use.

Some, like for a woodburner, keep the heat going up and around the cook pot in a stack effect. Some are more for keeping external wind from blowing the heat away from the cook pot.

Often there is a round screen directly underneath a burner such as butane or white gas. That is intended to keep most of the heat reflected upward and not going down to overheat the butane or white gas fuel. Call that one a heat reflector. Of course you would never see that on a woodburner. On the other hand, some fuels need just a little bit of that heat to perform effectively. You have to know where the fresh air draft is coming from, where the hot air is going, and what the fuel system needs.

Each stove is a little different and the windscreen acts a little different. YMMV.
