Abstract: PURPOSE:To suppress deposition of carbides on the front surface of a fuel nozzle, by integrally casting a turbulator collar and a sweep ring by precision casting, and disposing a passage for a sealing air for the front surface of the fuel nozzle at an angle deviated in the direction of the center of the nozzle. CONSTITUTION:A fuel nozzle cap 2 is inserted into a turbulator collar 1 pro duced by precision casting. A portion 3a of compressed air 3 introduced into an inner tube of a combustor is led into an elbow-shaped groove hole provided in the turbulator collar to seal the front surface 2a of the cap 2. The compressed air 3 is given a swirling force by the turbulator collar, so that it enters the inner tube while swirling, thereby stirring sufficiently a mist form fuel oil, sprayed from a transition piece fitted in the fuel nozzle, and air. Since the air in the inner tube is swirled, the pressure at a central part of the interior of the inner tube is lowered, and the air on the downstream side is caused to flow backward, resulting in re-combustion of unburnt oil portions. Therefore, combustion efficiency is enhanced, and deposition of carbides on the front sur face of a fuel nozzle is suppressed.

Abstract: PURPOSE: To cool a bearing case sufficiently and promote the explosion-proof capacity by perforating small holes on the bulkhead of an inner air passage in the bearing case and conducting cooling air to a support part.  
     CONSTITUTION: A part of cooling air is circulated through an inner and an outer passage 4 and 5, and the second part is introduced into a cavity 15 from a labyrinth packing 3 for cooling work. Besides, in this cooling structure, the third part of cooling air is introduced into the cavity 15 through small holes 17 from the inner air passage 4, and dashed to diaphragm 18 to flow into gaps 19, At this stage, the air is mixed with lubricant, and discharged from a discharge pipe together with the lubricating oil to be exhausted to the open air in an oil tank. In this process, since the air jetted out through small holes 17 takes off heat from around small holes 17 and also from the diaphragm 18 as dashing to the diaphragm 18, the temperature in the bearing case 1 can be effectively reduced.
