Abstract (en)
[origin: EP0445393A2] A burner, in particular a forced-draught burner for heating boilers, combustion installations or the like, is proposed, which is provided with an air supply device, a fuel supply device (15) which introduces liquid or gaseous fuel, a flame device (14) which penetrates into a combustion chamber (11) and forms the burner flame (18), and a waste gas return duct (20) which returns to the air supply device part of the waste gases formed during combustion. A region of the waste gas return duct (20), which during operation of the burner (13) has a temperature above the dew point of the waste gases, is provided with at least one supply opening (22) for outside air. By virtue of the inflowing dry outside air, which mixes with the waste gases, the dew point is on the whole reduced to such an extent that it lies below the temperatures prevailing in the waste gas return circuit. As a result of this, the condensation in the burner and thus the corrosion in the burner can be prevented in a simple manner. <IMAGE>
