What is an implication of having too much air in the combustion process?

Having too much air in the combustion process primarily leads to decreased efficiency. This outcome occurs because excess air dilutes the fuel-to-air ratio needed for optimal combustion. When there is an abundance of air, it can cause the flame to burn cooler and result in incomplete combustion. The lack of the proper ratio can also lead to energy loss as more energy is required to heat the extra air that does not contribute to combustion.

In a well-balanced combustion process, the goal is to ensure that the right amount of fuel mixes with just enough air to support complete combustion. When this balance is disrupted by excessive air, it hampers the overall efficiency of the burner and system.
