What can excessive oxygen in the combustion process lead to?

Excessive oxygen in the combustion process can lead to lower efficiency. When there is too much oxygen in the combustion chamber, it indicates that not all of the fuel is being utilized effectively. This excess oxygen can dilute the flue gases and lead to incomplete combustion, where the fuel does not burn fully. As a result, the energy content of the fuel is not maximized, and much of the potential energy is wasted, leading to a decrease in overall efficiency of the boiler system.

Additionally, when the combustion process is not optimal due to an excess of oxygen, the temperatures can also be adversely affected, which can further impact the efficiency of energy conversion in the boiler. Maintaining the right balance of fuel and oxygen is crucial for achieving optimal combustion efficiency and ensuring that the energy produced is used effectively.
