BURNER WITH LOW TEMPERATURE LID Russian patent published in 2023 - IPC F23D14/04 

FIELD: power engineering.

SUBSTANCE: burner (100) comprises a body (1) adapted to accommodate at least one nozzle (2), a crown (3) placed on the body (1) and a cover (4) placed on the crown (3), whereas the crown (3) comprises: a side edge (31) in the form of a truncated cone, the diameter of which decreases in the direction from bottom to top, and the angle of inclination of which is 20°-70° relative to the horizontal plane, a plurality of openings (30), which are U-shaped when viewed from the front which pass radially in the side edge (31) of the crown and are intended for the release of flames, whereas the cover (4) has a side edge (40) comprising: the first part (40a) in the form of a truncated cone, made with a downward slope at an angle of approximately 10°-25° relative to the horizontal plane, and the second part (40b) in the form of a truncated cone, made with an inclination downward at an angle of approximately 30°-70° relative to the horizontal plane; and a bottom surface (41) that is inclined at an angle of approximately 8-25° relative to the horizontal plane and located over the openings (30) of the crown.

EFFECT: invention makes it possible to reduce the temperature of the lid and create an efficient, reliable, inexpensive and easy-to-manufacture burner.
