Description
10 15 20 25 55 gvsozzss-z i f 2 ligt uppfinningen. Fig 5 och 4 visar två, olika konstruktiva, utformningar av ventilen enligt uppfinningen. mg 1 visar en gasflfirbinanläggfsng omfattande en kompressor 1, gester-bin 2 och två. brännkamrar 3. Tryckluften leds. från kompressorn till en varje b omgivande mantel 4 genom ett yttre rör 5 som omger ett inre rör 6 som leder de heta gaserna från brännkammaren till turbinen. 10 15 20 25 55 gvsozzss-z i f 2 according to the invention. Figures 5 and 4 show two, different constructive, designs of the valve according to the invention. mg 1 shows a gas turbine plant comprising a compressor 1, gesture bin 2 and two. combustion chambers 3. The compressed air is conducted. from the compressor to one each b surrounding jacket 4 through an outer tube 5 surrounding an inner tube 6 leading them the hot gases from the combustion chamber to the turbine.
Som ovan nämnts måste man vid användningen av en virvelbäddsbrännkannnare kunna avstänga. denna. helt och hållet från anläggningeni tillfälleav störningar, såsom exempelvis lastbortfall eller haveri. Samtidigt måste kompressor-luften föras direkt till gasturbinen, dels för att inte bromsa upp kompressorn, dels för att kyla turbinen. Principen härför framgår av fig 2, där avspärrnings- ventilerna 7 ooh B har ineattsi luft- respektive gasledningen 5 respektive 6, . medan förbigångsventilen9 har insatta mellan nämnda två. ledningar. vid betjäningen av dessa ventiler gäller att ventilerna. 7 och 8 inte får stängas av innan förbigåxzgaventilen 9 har öppnats för att undvika häftiga uppbromsningar av luftströmmenpuFör att säkra. detta koordineras manöverorganen för ventilerna lämpligen så. att ventilen 9' öppnas innan man börjar stänga av ventileras. 7 och e. ' e p Vidare måste brännkammaren kunna avlestas efter avstängningen, vilket kan ske medelst en speciell ventil 10, en s k dumperventil, som leder till anläggningens skorsten eller avg-anledning. Vid haveri är detta den enda möjligloeten. Är det däremot bara fråga., om laatbortfall kan brännkanmaren långsamt avlastes till tur- binen om: bara luft- och bränsletillförseln är spärrade. Härvid kan man utnyttja. det förhållandet att det vid aktuella. dimensioner och temperaturer ändå. är e svårt att göra ventilerna 7 och 8 helt täta utan risk för att de kan klänmas fast i stängt läge. Man utformar därför dessa ventiler med ett visst glapp och säkrar att ventilen 8 ständigt har större glapp än ventilen 7. Pâ. så. vis komer brännkammaren att långsamt avlastas över ventilen 8, medan lufttillförselzx över venmen 7 m1- försumbar.As mentioned above, when using a fluidized bed burner burner, one must be able to shut down. this. completely from the plant in the event of disturbances, such as cargo loss or breakdown. At the same time must compressor air carried directly to the gas turbine, partly so as not to slow down the compressor, partly to cool the turbine. The principle for this is shown in Fig. 2, where the barrier the valves 7 ooh B have ineattsi the air and gas line 5 and 6, respectively, . while the bypass valve 9 is inserted between said two. management. when operating these valves, the valves apply. 7 and 8 must not be closed off before the bypass valve 9 has been opened to avoid violent braking of airflowpuTo secure. this coordinates the actuators of the valves suitably so. that the valve 9 'is opened before starting to switch off is ventilated. 7 and e. 'e Furthermore, the combustion chamber must be able to be read after shutting down, which can happen by means of a special valve 10, a so-called dumper valve, which leads to the plant chimney or avg reason. In the event of an accident, this is the only possible option. Is it on the other hand, just ask., if late loss, the combustion chamber can be slowly relieved to bees if: only the air and fuel supply are blocked. You can take advantage of this. the fact that it at current. dimensions and temperatures anyway. is It is difficult to make valves 7 and 8 completely tight without the risk of them becoming clamped fixed in closed position. These valves are therefore designed with a certain play and ensures that the valve 8 always has a larger play than the valve 7. On. so. show comer the combustion chamber to be slowly relieved over the valve 8, while the air supply is over venmen 7 m1- negligible.
Den konstruktiva. utformningen av ventilkombirzationen enligt uppfinningen framgår av fig 3, där ventiler-na är placerade i ett hus 11 på. en vinkelböjning på. koaxial- ledningen S, 6.The constructive. the design of the valve combination according to the invention appears of Fig. 3, where the valves are located in a housing 11 on. an angular bend of. coaxial- line S, 6.
Ventiler-na. 7 och 8 utformas lämpligen som dubbla klaffventiler och som framgår av ritningen går den inre gasledningen 6 fram i 'en obruten böjning, medan luft- ledningen 5 avbryts så. attventilen 7 mynnar fritt i huset 11.Ventiler-na. 7 and 8 are suitably designed as double flap valves and as shown of the drawing, the inner gas line 6 advances in an unbroken bend, while the air line 5 is then disconnected. the valve 7 opens freely into the housing 11.
