What does the introduction of secondary air do?

The introduction of secondary air plays a critical role in the combustion process by enhancing the efficiency of burning combustible gases. When secondary air is introduced, it mixes with the primary fuel-air mixture after it has already started burning. This additional air provides the necessary oxygen for the complete combustion of the fuel, which helps to ensure that more of the fuel is burned, reducing the amount of unburned hydrocarbons and improving overall combustion efficiency.

By facilitating a more thorough combustion process, the introduction of secondary air helps to lower emissions and maximize energy output from the fuel used. This is especially important in stationary engineering applications, where both performance and environmental considerations are paramount. Efficient burning not only results in effective energy use but also contributes to cleaner exhaust emissions, aligning with modern standards for environmental protection.
