The triangle TLUD plate works with the Afterburners in the Core 3 or Core 4 (in three sided mode) stove to re-burn the smoke.
Using the Triangle TLUD plate, filling the stove with fuel to the bottom of the afterburner ports will allow you to cook for about 20+ minutes, with a controllable, steady, hot flame. No Smoke, no Stoke.
*Requires Afterburner plates in order to work.
*Does not work with the Core M4 or Core Recon.
Check out this video made by a Gen 1 Core 3 owner of the stove burning in wood gas mode with 3 afterburners and the triangle TLUD plate.
