BURNER FOR FUEL IN FORM OF PARTICLES Russian patent published in 2016 - IPC F23D1/02 

FIELD: energy.

SUBSTANCE: invention relates to power engineering. Burner (1) for particulate fuel, in particular biomass having a primary pipe (3) and one in primary pipe (3) disposed core tube (2), wherein primary pipe (3) and core tube (2) forming a primary tube gap (4) for guiding a flow of particulate fuel and gaseous oxidant from an inlet end to the hole of primary tube (3) on outlet side of core tube (2), in longitudinal direction of burner (1), ends before primary tube (3), wherein also provided is at least one device for centering flow within the primary tube (3) in end of primary tube (3) on outlet side. Axial distance between ends at output side of core tube (2) and primary tube (3) in longitudinal direction of primary tube (3) is at least 50 %, preferably at least 75 %, in particular, at least 100 %, of average width of primary tube gap (4). Core tube (2) converges towards its end on outlet side. At end on outlet side of core tube (2) in primary tube gap (4) there is a deflector to deflect inside close to core tube part of flow in primary tube gap (4).

EFFECT: technical result is reduction of NO_X.
