BURNER DEVICE Russian patent published in 2013 - IPC F23D17/00 F23R3/28 F23D14/76 

FIELD: power engineering.

SUBSTANCE: burner device of a plant for combustion of fluid types of fuel comprises a burner bushing (18), at least one channel (3, 4) for air supply, and at least one channel (9, 13, 19, 23) for supply of the appropriate fuel, at the same time at least one channel (9, 13, 19, 23) for fuel supply is arranged at least partially inside the burner bushing (18), at least in one channel (23) for fuel supply there is a screening wall (30), which is at the distance from the wall (21) of the channel (23) for fuel supply, besides, between the wall (21) of the channel (23) for fuel supply and the screening wall (30) there is an intermediate space (38), which does not relate to the path of the fuel flow passing via the channel (23) for fuel supply, at the same time the screening wall (30) is formed with a case (30) inserted into the channel (23) for fuel supply and equipped with at least one radial positioning facility (33, 35) providing for the distance (s) between the case (30) and the wall (21) of the channel (23) for fuel supply, at the same time at least one radial positioning facility (33, 35) of the case (30) is arranged in the form of at least one circularly arranged positioning ledge (33,35) protruding radially outside.

EFFECT: invention makes it possible to reduce stresses in a burner bushing from received heat.
