System and method for operating a combustion chamber

A method for operating a combustion chamber comprising:

• obtaining a carbon monoxide reading at an exit of the combustion chamber via a carbon monoxide sensor;
• deriving an oxygen set point trim based at least in part on the carbon monoxide reading and a carbon monoxide set point via a controller;
• determining a stability status of the combustion chamber via a combustion stability sensor;
• via the combustion stability sensor, determining that the stability status of the combustion chamber is above a threshold indicating a stable combustion condition, and in response, adjusting an oxygen set point of the combustion chamber with the oxygen set point trim via the controller;
• and
• via the combustion stability sensor, determining that the stability status is below the threshold indicating a poor combustion condition, and in response, maintaining the oxygen set point at its prior value until the stability status is above the threshold;
• wherein the oxygen set point defines a desired oxygen level at the exit of the combustion chamber.
