Abstract
The invention relates to a burner with a refractory burner body 1, 2, 3 for burning liquid or aerosol fuels, in particular, gaseous fuels. With the aim of reducing NOx emissions, the burner body comprises a gas nozzle 7, 9, 10, 11 and a plurality of air nozzles 4, 6, which are at least partially formed as integral mouldings in the burner body and flow out on a front side 16 of the burner body. Here, the air nozzles are symmetrically arranged around the gas nozzle and diverge at an angle α to the gas nozzle. Likewise, the invention relates to a method for burning liquid or aerosol fuels, in particular, gaseous fuels with reduced NOx emissions.
