Combustion is complete and achieves maximum efficiency if all the oxygen in the combustion air is burned. In case of this theoretical combustion, there is no residual oxygen left in the combustion gases. In this process, the amount of air is crucial: too much air results in a lower combustion efficiency, while too little air leads to incomplete combustion and CO (carbon monoxide) in the flue gases.
In case of CO regulation, the amount of CO in the flue gases is continuously measured and the burner manager automatically reduces the air supply until it detects traces of CO. In this way, the burner manager can achieve the most optimal combustion in any situation, fully automatically.
