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 an excess
supply of air (excess O2) 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.
