BURNER FOR A HEATER FOR THE COMBUSTION OF LIQUID OR GASEOUS FUELS AND UNIT FROM A BURNER AND A HEAT EXCHANGER

摘要

The invention relates to a burner (10) for a heater for the combustion of liquid or gaseous fuels. Said burner comprises a mixture-producing chamber (16) in which a combustible gas mixture can be produced from the fuel, and a cylindrical fire tube (22). Said fire tube is arranged downstream of the mixture-producing chamber (16) in a direction of flow (S) of the combustible gas mixture and defines a combustion chamber (34). The fire tube (22) has a jacket (30) extending in the direction of its longitudinal axis (A) and is closed at a front facing away from the mixture-producing chamber (16). The jacket (30) comprises a plurality of outlet openings (31) that are axially distributed across the periphery of the jacket (30) and through which combustion gas (20) from the combustion chamber (34) of the fire tube (22) can be discharged.
