High heat liberation hearth burners are located adjacent to the inlet sections of the coils and lower heat liberation burners are located adjacent to the outlet sections. The secondary fuel tips of the burners are inclined toward the adjacent heater wall. The high heat liberation hearth burners adjacent to the inlet coils are arranged in spaced apart pairs with the secondary burner tips of each of the pair being inclined toward the other burner of the pair.
