What is the purpose of secondary air in the incinerator?

The purpose of secondary air in an incinerator is to enhance combustion efficiency by providing additional oxygen to the combustion chamber. This helps to ensure that any unburned or partially burned gases are fully oxidized, reducing emissions of harmful pollutants and improving overall combustion stability. By promoting complete combustion, secondary air also contributes to the effective breakdown of waste materials and minimizes the generation of residual ash.
