Abstract
The dry oxygen content in the exhaust of an industrial furnace may be controlled to 1% or less by determining one or more of: the temperature of: each or a group of one or more burner (flame); one or more section of the radiant walls adjacent (e.g., within 5 feet of the burner); the temperature gradient across the process coils; the combustion products of one or more burners; the mass flow rate or the volume flow rate of air to each burner (e.g., the pressure drop across the variable forced air aperture
