FIELD: heat-and-power generating plants. SUBSTANCE: injector has body 1 with fuel pipe 2 and two pairs of coaxial shells 3 and 4, 5 and 6 with annular clearance inside each pair; annular clearances are facing each other at certain angle. Shells 3-6 are truncated cones. Pair of shells 3 and 4 faces body 1 by its smaller bases and pair of shells 5 and 6, by larger bases. Annular clearance of each pair receives partitions placed in same plane and each of them is continuation of other one when one pair of shells leaves one annular clearance and enters other one. Annular row of coaxial holes 7-10 is provided in shells to form alternating blind and through ducts 13 and 14. Large bases of shells 3 and 4 may have diameter greater than that of smaller base of shell 6; inlet edge of shell 4 may be made so that it abuts inlet edge of shell 5. EFFECT: enlarged functional capabilities. 3 cl, 2 dwg
