What is the primary reason for chamberless firing in oil burners?

Chamberless firing in oil burners is primarily aimed at achieving better heat transfer. This design eliminates the traditional combustion chamber and allows for a more efficient combustion process by optimizing the mixing of fuel and air. This results in a more complete burn of the fuel, which enhances the overall efficiency of the burner system.

The improvement in heat transfer occurs because without a combustion chamber, the heat produced by the burning fuel can be transferred more directly to the heating medium, such as water or air. This design minimizes heat loss and provides greater temperature control, which is essential in heating systems.

While other factors such as maintenance, emissions, and safety are important considerations in the design and operation of oil burners, the key advantage of chamberless firing relates to its ability to maximize the efficiency of heat transfer. This focus on efficiency not only improves performance but can also contribute to reduced fuel consumption over time.
