The general idea... just brace the screen as a wind break...
closer (though blurry) pic...
From behind...
This may be a little close... the idea is to use this like Jim Wood's kitescreen... the curve and closeness can be adjusted to suit.

Definitely DON'T use the burner this way... too great of a chance of heating up the stove / canister. Caldera cones get VERY hot inside...
Way too tight to use fully enclosed.
