ABSTRACT:
A burner for burning liquid or gaseous fuels, especially heavy heating oil. A central fuel lance is surrounded by two annular channels that supply primary and secondary combustion air. The annular channels are surrounded by several outer fuel lances that are distributed along the arc of a circle and can optionally be displaced axially and by air nozzles that convey tertiary combustion air. The object is to burn fuel at a low output of pollutants in systems with a narrow combustion space. The burner has an annular flue-gas channel between the outer annular channel and the air nozzles. The burner opens into a chamber that is jacketed in ceramic and that a heat exchanger (flame tube) extends out of. Other nozzles that convey a component of the flow of tertiary air are mounted in the wall of the chamber.
