It is often incorrectly assumed that the burner tile is simply a piece of refractory or firebrick. Nothing could be further from the truth. The burner tile is the “heart” of the burner. Tile that has not been poured correctly, installed correctly or that has not been properly maintained can have a serious impact on burner performance.
Burner tiles, sometimes called quarls, are an important component in burners.1 Tiles are typically made out of some type of ceramic and serve many different purposes, including:
Protecting the metal components inside the burner from the heat in the combustion chamber
Shaping the flame
Radiating heat: these burners are commonly called radiant wall burners
