FIELD: mechanical engineering. SUBSTANCE: invention relates to fuel afterburning device using for its operation carburetor type flame stabilizer featuring optimized cooling system. Flame stabilizer has housing 34 passing in radial direction in primary gas flow. Flame stabilizer housing is a structure made in form of V-shaped dihedral angle with two side plates 35, 36 provided with common rounded-off rib 37 uniting the plates, vent tube 38 located between two side plates 35, 36 and at least one fuel pipeline 44, 45 arranged in rib of vent tube 38. Vent tube 38 has triangular cross-section and chute 42 on its rear surface relative to flow. Fuel pipelines 44, 45 are placed in chute 42. Vent tube 38 has holes 41, 46 designed for intensive cooling of side plates 35, 36 of dihedral angle structure and fuel pipelines 44, 45. EFFECT: improved cooling. 3 cl, 4 dwg
