FIELD: furnace chamber of gas-turbine plants. SUBSTANCE: flame tube is made in form of section of pipe provided with thermal shield made from bricks 5. Thermal shield 4 is directed towards inner zone 2 and is secured by means of at least one metal bearing frame 6 provided with many cooling gas supply passages 7 and shoulder 9 whose passages are mainly closed in direction towards inner zone 2 at clearance 8. Bearing frame 6 may be reliably shielded against hot gas due to availability of cooling gas film formed above bearing frame 6 by cooling gas fed through passages 7 and clearance 8 without disturbing the hot gas flow. EFFECT: enhanced reliability. 4 cl, 4 dwg
