Abstract: An oil premix burner comprising: a combustion element; a burner surface on the outer lateral surface; a distribution chamber below the burner surface; a central oil injection device; a combustion air channel connected to a blower situated upstream as well as an air heat exchanger for the preheating of the combustion air in the area of the burner surface. In each case, the annular space formed between the inner tube and the outer tube of all the double tube elements opens out into an annular-shaped collecting chamber, and the preheated combustion air, starting from the collecting chamber, flows inwards via a swirl-generating device into the area around the oil injection device into the distribution chamber.
