Abstract
A thimble shaped burner is made of a porous foam metal material and is adapted to be mounted on the interior of a plenum chamber receiving a fuel/air mixture under pressure. The fuel/air mixture infuses into the interior of the thimble shaped burner body and exits from it through a burner port in a support structure where the fuel/air mixture that has been infused through the burner body is ignited. The burners are typically used in multiples and are mounted by means conventional fasteners passing through reinforced mounting flanges on the interior of an air fuel plenum chamber. Flame lift off is reduced or eliminated by particular configurations and dimensions of annular metal washers that are used in association with the burner bodies for mounting purposes.
