BURNER AND METHOD OF ITS MANUFACTURING Russian patent published in 2025 - IPC F23D14/62 F23R3/12 

FIELD: power engineering.

SUBSTANCE: burner has combustion space (1), plurality of swirling ducts (2), wherein swirling duct (2) comprises at least one fuel nozzle (3) for introducing fuel (G) into corresponding swirling duct (2), wherein each swirling channel (2) extends from inlet side (21), on which fuel (G) from corresponding fuel injector (3) is capable of being introduced into swirling channel (2), to outlet side (22) leading into combustion space (1), and each of swirling channels (2) is capable of passing along flow path (23) passing from inlet side (21) to outlet side (22), fuel-air mixture of fuel (G) and air (L), flowing into swirling channel (2), wherein burner has central axis (X) passing through combustion space (1), and swirling channels (2), outgoing from outlet side (22), are helically twisted around central axis (X) at least partially so that fuel-air mixture flowing from inlet side (21) along flow path (23) to outlet side (22), in each case is subjected to swirling by means of swirling channels (2) and flows into combustion space (1) in swirling form, wherein each swirling channel (2) has an annular cross-section and is made in the form of a swirling tube, swirling channels (2) of a plurality of swirling channels (2) are adjacent to each other, each of swirling channels (2) contains a wall limiting corresponding swirling channel (2) in the radial direction, and walls of swirling channels (2), which are adjacent to each other, are made as a whole and/or in the form of one part.

EFFECT: invention will allow providing high resistance to reverse impact of flame, good mixing of air with fuel, reducing level of emissions.
