Some combustion processes, e.g. process heaters, steam boilers or heating furnaces the air required to achieve optimal system efficiency can easily fluctuate. And the economic optimum of the process fluctuates within a relatively narrow range.

Both elevated NOx or SOx emission due to excess supply of air (O2 excess), as well as energy loss within the system due to incomplete combustion (lack of O2 ) require measuring the oxygen level in the flue gas of the combustion process. Sampling near the combustion chamber is therefore just as vital as using a rapid response sensor to allow for responding to changes in the combustion gas temperature and/or other variables in the combustion process promptly.
The BA 2000 was developed specifically for this application.
