<p>PURPOSE:To enable to fix an inner tube to a cone guide without causing relative displacements in case of receiving external forces such as a combustion vibration and the like, in a combustion device equipped with an outer tube, the inner tube, the cylindrical cone guide provided at the inside of the inner tube and a fuel nozzle. CONSTITUTION:In a combustion device, consisting of an outer tube 1, an inner tube 2, a cylindrical cone guide 4 provided at inside of the inner tube 2, an end- plate 6 integral with a part 3 of the cone guide and a fuel nozzle 7 penetrating the cone guide at the center portion thereof, a plurality of holes 15, opposing to inflated portions 14 formed by inflating several parts on the outer peripheral surface of the cone guide 12 toward the inner tube, are formed on the peripheral surface of the inner tube 11. Inner tube fixing members 16, being formed with surfaces engaging with the inflated portions 14 on one ends thereof, are inserted through the holes 15 and the other ends thereof are welded to the outer peripheral surface of the inner tube 11, thereby, the inner tube 11 is fixed. A retainer 17 is interposed between the inner tube 11 and the cone guide 12 at the side of an end plate 13 and is attached to the plate 13.</p> |
