A combustor 13 comprises a double structure of an inner cylindrical member 13a and an enlarged outer cylindrical member 13b to thereby enlarge a diameter of a combustion zone. A pre-mixing nozzle 11 comprises an outer sleeve 23 of which front end is projected beyond a base plate 17 and a pre-mixing nozzle portion 21 of the inner side. Air flows between the outer sleeve 23 and the pre-mixing nozzle portion 21 for enhancing the cooling effect of the pre-mixing nozzle 11. High temperature gas inner and outer circulating flows 15, 16 are formed in the combustion zone to enhance the flame holding ability. Pilot fuel quantity, as so far necessitated for flame holding, is reduced and NOx quantity generated of the pilot fuel is reduced. The base plate 17 exposed to the high temperature gas is prevented from being overheated by the projected front portion of the pre-mixing nozzle 11.

The specific embodiment
Below, accompanying drawings is according to one embodiment of present invention.
Fig. 1 (a) and (b) schematically represent the gas-turbine combustion chamber of this embodiment, wherein Fig. 1 (a) is a longitudinal section, the inside of combustion chamber is shown, and Fig. 1 (b) is the front view of combustion chamber one side of something.At Fig. 1 (a) with (b), label 10 expression combustion chamber bodies, as the shell of combustion chamber, eight pre-mix nozzles 11 are located at wherein, and the axis that centers on combustion chamber body 10 interconnects.Pre-mix nozzle 11 structures are able to the outstanding substrate 17 that surpasses of its front end, and this will be in hereinafter explanation.Label 11 expression pilot jets, this pilot jet is arranged on the axis of combustion chamber body 10.Label 13 expression combustion chambers, this combustion chamber comprises combustion chamber body 10 and the miscellaneous part that is arranged in wherein.Cylindrical member 13a and Outer cylindrical member 13b in combustion chamber body 10 comprises therein.The internal diameter of Outer cylindrical member 13b is done both greater than the external diameter of interior cylindrical member 13a, again greater than the external diameter of the cylindrical member of the combustion chamber of prior art.Outer cylindrical member 13b arranges to such an extent that hold the leading section of interior cylindrical member 13a and the downstream of extending interior cylindrical member 13a, to cover the combustion zone of combustion chamber 13.Label 14 expression flames are kept cone, and this flame is kept cone and cancelled its leading section, and the flame that makes it to be shorter than prior art is kept cone.Label 17 expression substrates, this is the lip-deep member of inner peripheral wall of cylindrical member 13a in eight pre-mix nozzles 11 are supported to.
Fig. 2 is the longitudinal section of the amplification of one of pre-mix nozzle 11.The double structure of the outer sleeve 23 with inboard premix spray nozzle part 21 and outside is made in the front portion of this pre-mix nozzle 11.Omitted in the drawings, a plurality of ribs member supportings of outer sleeve 23 processes are on premix spray nozzle part 21.The pre-mix nozzle of prior art cuts off in substrate position at its front end, and is further not outstanding, and pre-mix nozzle 11 of the present invention is in the outstanding substrate 17 that surpasses of its front end.In other words, the outstanding forward position that surpasses substrate 17 of the front end of outer sleeve 23.Label 14 expression flames are kept cone, and this cone leading section is by the projection brachymemma of outer sleeve 23.Swirler blade of label 22 expressions, its structure is identical with prior art.
In the above combustion chamber of describing that sees figures.1.and.2, main fuel 40 flow in eight pre-mix nozzles 11 and with air pre-mixing to form premix, be used in the combustion chamber 13 combustion zone and burn.Air is by the inner rim spatial portion of compressor (not shown) supply with the combustion chamber body 10 of flowing through in the feed-in combustion chamber 13, shown in arrow 50 among Fig. 1 (a), flow through the then neighboring spatial portion of the premix spray nozzle part 21 and the premix spray nozzle part 21 of flowing through is shown in the arrow among Fig. 2 51.On the other hand, auxiliary fuel 41 infeeds in the combustion chamber 13 through the pilot jet 12 of center, combustion chamber, and burns with premix in this chamber.
Preceding central space portion in that the flame of pilot jet 12 is kept cone 14 produces circular flow 15 in the high-temperature gas by auxiliary fuel.In addition, the inner rim spatial portion at the Outer cylindrical member 13b of pre-mix nozzle 11 fronts produces high-temperature gas outer circulation stream 16 by the premix that enters from pre-mix nozzle 11.Thereby, carry out flame reliably and keep by these two circulating currents 15,16.Because the structure of combustion chamber 13, be cylindrical member 13a and Outer cylindrical member 13b in combustion chamber 13 comprises, and do the internal diameter of Outer cylindrical member 13b greatlyyer, thereby in the inner rim spatial portion of the front Outer cylindrical member 13b of pre-mix nozzle 11, form the gas stagnant area.Like this, the high-temperature combustion gas that produces along with the burning of main premix circulates, and forms high-temperature gas outer circulation stream 16 in this gas stagnant area.
Keep the flame that circular flow causes in the high-temperature gas that cone 14 produces and keep along with increasing flame, because the structure of circulating current and outer circulation air-flow 15,16 in the high-temperature gas has been strengthened flame widely and kept ability.Thereby, keep needed auxiliary fuel consumption for flame so far and can reduce, thereby can reduce the NOx that auxiliary fuel produces, realize the burning of very low NOx.
As the explanation that reference Fig. 2 is done, pre-mix nozzle 11 comprises swirler blade 22, premix spray nozzle part 21 and outer sleeve 23.The premix spray nozzle part 21 that outer sleeve 23 is arranged inboardly with it keeps predetermined gap, and shown in arrow among Fig. 2 51, air flows into this gap, thereby can cool off mix nozzle portion 21 and the outer sleeve 23 that is subjected to the high-temperature gas heating effectively.
And, the front end of the pre-mix nozzle 11 that forms by the front end of outer sleeve 23, the outstanding substrate 17 that surpasses.Owing to the part of this projection, prevent from directly to be exposed to substrate 17 superheated of high-temperature gas outer circulation stream 16.Among Fig. 2, L is the outstanding distance of jut, the just front side surface of substrate 17 and the distance between mix nozzle 11 front ends in advance, and D is the external diameter of pre-mix nozzle 11, the external diameter of outer sleeve 23 just, if L is set to D/3 or above (L 〉=D/3) just can improve the effect that prevents that substrate 17 is overheated.
Fig. 3 is and the identical view of Fig. 1 (a), has wherein increased hatched part.In Fig. 3, alphabetical P is defined as centring ring, and centring ring is the central axis circle all disposed thereon of all pre-mix nozzles.Internal diameter corresponding to the Outer cylindrical member 13b of the diameter of combustion zone in the combustion chamber is to set like this, make when on the sagittal plane of combustion chamber, measuring area, be in the outside of the inboard of Outer cylindrical member 13b and centring ring P area, deduct pre-mix nozzle 11 at the shared area in the outside of centring ring P, that is to say, among Fig. 3 the shared area of dashed area be all pre-mix nozzles 11 area half or over half.By the diameter in such selective combustion Indoor Combustion district, in the preceding outer space portion of pre-mix nozzle 11, form the above-mentioned gas stagnant area effectively, keep ability thereby can improve flame widely.
According to the gas-turbine combustion chamber of above-mentioned formation, can be reduced the effect of NOx significantly.For example, the amount of NOx can be reduced to 10PPM or following by the 25PPM of prior art.
Although described the preferred embodiments of the present invention in the above, should be appreciated that to the invention is not restricted to concrete structure and arrangement illustrated and that describe here, but comprise its modification that falls in claims scope.
