Does anyone know how to calculate where (how high from bottom of tank) to place the reverse flow plate/baffle? It seems to me that if you calculate the sizes of your firebox, plate gap and chimney size, that the area below ( and above) the reverse flow plate/baffle would be important too. We're about to start building a new competition rig and want it to be the best it possibly can be. Thanks.

My understanding is that your plate should be high enough to give the same area as the opening of the firebox/cook chamber and plate gap.  So if you have a 120 square inch opening from your fb to cook chamber, the area under a given portion of your tank should be the same.  If you're using a cylindrical tank (like a propane tank) and a square fb, it should be about at the upper opening of the fb.  There is a website that will help you figure this.  Plug in your tank radius and the height of a segment (possible distance above bottom of tank for plate) and keep messing with it until you approximate your square inches needed.  Hope this helps.    ...  

I cant get this link to work...does anybody have a different link or site that would help get these dimensions? is reader supported and as an Amazon Associate, we may earn commissions from qualifying purchases.
