Abstract: An oil burner for heating installations is provided, having a burner housing comprising a perforated evaporating tube which is equipped with a circular series of blades to impart a twisting motion to the air and a cone-shaped guiding piece to impart an injection effect to the air, and which has attached thereto and maintained at a fixed distance therefrom a perforated, disk-shaped baffle. The present burner arrangement provides for a complete and soot-free, stoichiometric combustion wherein a blue flame is generated with extremely low level of noise.
