What can help eliminate extinction pop by reducing the air supplied to the burner?

Reducing the air supplied to the burner can help eliminate extinction pop, which is a combustion phenomenon that can occur in certain burner applications. Primary air is the air that is mixed directly with the fuel as it enters the combustion chamber, playing a crucial role in ensuring that combustion is stable and efficient. By controlling and reducing the amount of primary air supplied to the burner, the combustion conditions can be optimized to reduce the chances of incomplete combustion, which is often a factor in extinction popping.

In situations where there is too much primary air, the flame may become unstable, leading to fluctuations in combustion and potential extinction. By reducing the primary air, the fuel-to-air ratio can be adjusted to more appropriate levels, thereby minimizing the risk of extinction pop by promoting a steadier and more stable flame.

The other options serve different purposes. Secondary air is typically used to enhance combustion and help in the complete burning of gas or vaporized fuel. Surplus air refers to the additional air supplied beyond the stoichiometric requirement, which can actually lead to worse combustion stability issues. Inlet air is a broader term that may include any air that enters the system, but does not specifically address the reduction of air to the burner for controlling extinction pop.
