Safely Maximize Heat Production
Efficient heat generation is essential for maximum energy input into your refining processes. Low levels of oxygen create dangerous environments with excess combustible fuels in the refining process. Sub-stoichiometric combustion carries other risks of possibly tripping the heater or even causing heater damage. While high levels of oxygen provide an added margin of safe heater operation, they negatively affect thermal efficiency and environmental compliance. Optimizing your oxygen levels with a Rosemount(TM) oxygen analyzer will ensure maximum heat production and safe process conditions.
