Abstract

1. Burner (100) for a solid fuel-fired boiler (40) with a heat exchanger for the heating of water and with a fuel storage space (41) and a combustion chamber (42) disposed therebelow separated by the burner, in which the burner (100) is comprised of a burner firing block (20) horizontally arranged in the boiler (40) with a perforation (21; 121) interconnecting the fuel storage space (41) with the combustion chamber (42) in order to form a gasification zone, and a blower (50) supplies primary air to the fuel storage space (41) and secondary air to the burner (100) within the area of the perforation (21; 121) in a controlled manner, in which the perforation (21; 121) possesses a circular cross-section with radii (R1 ) which decrease in size from the fuel storage space in the direction of the combustion chamber (42), characterized in that the perforation (21; 121), in order to decelerate the combustible gases, in its effective cross-section from the fuel storage space (41) in the direction of the combustion chamber (42), is constructed so as to increase in size, while in the perforation (21; 121), the truncated cone (30; 130) is disposed while forming an annular gap (31; 131) between the truncated cone surface (32; 132) and the inner area (22; 122) of the perforation (21; 121), in which the radii (R1 ) of the circular cross section of the perforation (21; 121) decrease more substantially in size from the fuel storage space (41) in the direction of the combustion chamber (42).
