Description

10 15 20 25 50 -~ 7907687-3 Enligt uppfinningen är gasgeneratorns tryokkärl omgivet av ett skal som tillsammans med tryckkärlet bildar en spalt. Skalet är vid sin nedre ooh övre del utfomat med öppningar genom vilka spalten står i förbindelse med omgivande atmosfär. En kylande luftström erhålles genom skorstensverkan när gasen i spalten uppvärmes av den varma tryckkärlsväggen. Rent automa- tiskt erhålles större drivkraft och kraftiga gasströnmingar och därmed kylning vid 'ökande väggtemperatur. Skalet som omger tryckkärlet kan vara försett med ett vämeisclerande skikt för att maximal drivkraft och hög strömxingshastiglzet skall erhållas. För reglering av luftströmningen och kylningen finnes ett spjäll placerat i en av öppningarns i skalet. 10 15 20 25 50 - ~ 7907687-3 According to the invention, the pressure vessel of the gas generator is surrounded by a shell which together with the pressure vessel forms a gap. The shell is at its lower ooh upper part formed with openings through which the gap communicates ambient atmosphere. A cooling air flow is obtained by the action of a chimney when the gas in the gap is heated by the hot pressure vessel wall. Rent auto- greater driving force and strong gas currents are obtained and thus cooling at 'increasing wall temperature. The shell surrounding the pressure vessel may be provided with a heat-absorbing layer for maximum driving force and high the flow rate shall be obtained. For regulating the air flow and cooling, there is a damper placed in one of the openings in the shell.

Uppfinningen beakrives närmare under hänvisning till bifogade schematiska o I figuren betecknar 1 gasgenerator som innehåller ett klotformigt tryck- kärl 2. I tryckkärlet 2 finnes en ringfomad brännkammare 3 i vilken för- bränning m: ren fiulaiama bada 4. mryexkäriev 2 och tremanna; 3 bäres upp av pelare 5. Eörbränningsluft tillföres brännkaxmnaren 5 genom luftfördelningskammare 7 och en perforerad botten 6. Luftmängden regleras genom spjäll 8 vid fördehiingsksmmarens 7 botten. I br väggar finnes Ivlrör 10 som 'begränsar vägg-temperaturen. Gas från 'brännkammaren 3 renas i renare 12 och 13 och samlas i ett ring-format samling-srör 14 och lades därifrån genom ledningen 15 till en icke visad gasturbin. Rummet 17 tillföras förbränningsluft från en kompressor genom det ringfomade ut- ryzmnet 25 mellan rören 15 och 27. _Pilar visar gaeströmningen.The invention is described in more detail with reference to the accompanying schematic O In the figure, 1 denotes a gas generator which contains a spherical pressure vessel 2. In the pressure vessel 2 there is an annular combustion chamber 3 in which burning m: pure fiulaiama bada 4. mryexkäriev 2 and three men; 3 carried by pillars 5. Ear-burning air is supplied to the combustion chamber 5 through air distribution chamber 7 and a perforated bottom 6. The amount of air is regulated through dampers 8 at the bottom of the distribution chamber 7. In br walls there is Ivlrör 10 which 'limits the wall temperature. Gas from the combustion chamber 3 cleaned in cleaners 12 and 13 and collected in a ring-shaped collection tube 14 and was passed from there through line 15 to a gas turbine (not shown). Room 17 combustion air is supplied from a compressor through the annular outlet ryzmnet 25 between the tubes 15 and 27. _Arrows show the gas flow.

Tryckkärlet 2 är omgivet av ett skal 16 som utvändigt är klätt med isole- rande material 1e. Mellan tryokkärlet 2 och skalet 16 bildas en spalt 19.The pressure vessel 2 is surrounded by a shell 16 which is externally clad with insulating material. edge material 1st. A gap 19 is formed between the pressure vessel 2 and the shell 16.

Vid skalets nedre och övre del finnes öppningar 20 resp 21. I den övre öppningen 21 finnes ett spjäll 22 för reglering av luftströmnixxgen i spalten 19. ' I Genom uppvärmning av luft i spalten erhålles drivkraft som åstadkommer en luftströmning som pilarna i spalten '19 visar. Gasgeneratorer av aktuellt slag för en större gasturbin kan ha en diameter av 15 m. Skorstensverkan kan därför bli betydande och en kraftig kylluftetröm kan erhållas.At the lower and upper part of the shell there are openings 20 and 21, respectively the opening 21 is a damper 22 for regulating the air flow nixxgen in column 19. 'I By heating air in the gap, driving force is obtained which provides an air flow that the arrows in the column '19 show. Gas generators of current stroke for a larger gas turbine can have a diameter of 15 m. Chimney effect can therefore become significant and a strong cooling air flow can be obtained.
