Abstract (en)
1. Burner for the stoichiometric combustion of a liquid or gaseous fuel comprising a fuel line (2) having a spray nozzle (3), an air tube (4) surrounding the fuel line which air tube is adapted to feed combustion air from a fan to the spray nozzle (3) and having a combustion tube (11) shaping the combustion chamber (12) and being connected to the air tube which combustion tube is made from a material having high temperature storing capacity, the end of which combustion tube facing the air tube (4) has an inlet opening (13) with a throttle (14) and to the opposite end of the combustion tube a cover plate (15) with a number of outlet openings (16, 16') is inserted, characterized in that the throttle (14) is shaped as a thickening (21) having in longitudinal section a triangular configuration and situated around the inner wall of the combustion tube (11) which thickening has inner wall surfaces (22, 23) each of which surrounding a truncated cone as a part of the inlet opening (13) respectively which inner wall surfaces merge in a concatenation region via a rounded region (24), and that the spray nozzle (3) is located where the throttle has its narrowest opening.
