Flat Flame Burner (FFB)

Flat Flame Burner

The Flat Flame Burner has a flared refractory outlet which produces a disc-shaped flame which “sticks” to the refractory wall or roof, thus creating a source of radiant heat. It is used in applications where no forward velocity can be tolerated. Typically these are kilns where the flame cannot be allowed to impinge on the ware, or large reheating furnaces, where they are installed in the roof to ensure good temperature uniformity by providing additional heat in the middle of the furnace. FFB Burners are also used for reheating glass sheets prior to bending.
