Fuel oil burner with converging flame tube - has cylindrical outlet on flame tube holding baffle plate downstream of swirler

摘要

The burner for fuel oil has a downstream converging flame tube. The fuel outlet is situated axially along the centre line of this flame tube. Air swirl is generated by a swirler downstream of air blower. A baffle plate is arranged downstream of swirler at the burner flame tube outlet. The burner flame tube has on its downstream narrow end a cylindrical part and the baffle plate (17) is arranged into this cylindrical part. The igniting electrode is situated upstream of the baffle plate in the vicinity of fuel outlet nozzle (16). The swirler (13) blade angle can be adjusted and the axial fan (12) blade angles can also be adjusted.
