Abstract

The cleaning device comprises an air intake cone (11) and motor part (12) arranged in series, in addition to nozzles (13) for spraying small amounts of finely divided liquid against the object. The nozzles are arranged symmetrically in the outer wall (111) of the cone, relatively close ot the boundary (112) between the cone and motor part. Jets of liquid (131) emerge from the nozzles at an angle of 0-71 deg. relative to a reference plane (113) extending through all the nozzles in the turbine flow direction (A).

Description

2 2 5 o 6 Ijiš - nu en: 2 Fig 2 visar i ett tvärsnitt fem dysor applicerade på insugningshomets yttervâgg; och Fig 3 visar samma vy som Fig 2 och med de fem dysoma utsprutande finfördelad tvättvätska. 2 2 5 o 6 Ijiš - now one: 2 Fig. 2 shows in a cross section five nozzles applied to the outer wall of the intake housing; and Fig. 3 shows the same view as Fig. 2 and with the five nozzles ejecting distributed liquid.

FÖREDRAGEN UTFöRnvGsFoRM I Fig 1 visas en del av ett insugningshorn 11 och en del av en motordel 12 till en gasturbin.PREFERRED EMBODIMENT Fig. 1 shows a part of an intake horn 11 and a part of an engine part 12 of a gas turbine.

Fem dysor, av vilka en dysa 13 år synlig, är symmetriskt installerade i insugningshomets ll yttervägg 111, relativt nära gränsen 112 mellan insugningshornet ll och motordelen 12.Five nozzles, of which one nozzle 13 is visible, are symmetrically installed in the outer wall 111 of the suction housing 11, relatively close to the boundary 112 between the suction horn 11 and the motor part 12.

Vätskestrålar 131 från dysan 13 ligger inom ett vinkelområde 0 - 71 fräknat från ett referens- plan 113 genom alla dysoma och i turbinens flödesriktriing A.Liquid jets 131 from the nozzle 13 lie within an angular range 0 - 71 counted from a reference plane 113 through all the nozzles and in the fate direction direction A of the turbine fl.

Genomförda långtidsförsök med tvättning av turbinkompressorer med den nya anordningen, när dessa är i drifi, har entydigt visat inte bara att den nämnda nackdelen (orsakad genom avställning av kompressorn) eliminerats, utan även att oljeförbrukningen under drifi minskat med ca 1%. Därigenom minskar också emissionema C02 (koldioxid) och Nox (kväveoxid).Long-term experiments with washing of turbine compressors with the new device, when they are in drive fi, have clearly shown not only that the mentioned disadvantage (caused by shutting down the compressor) has been eliminated, but also that the oil consumption during drive fi has decreased by about 1%. This also reduces emissions of CO2 (carbon dioxide) and Nox (nitric oxide).

Några negativa effekter av att spruta vätska in i turbinen då denna år i drift har ej observe- rats. Intervallet mellan två tvättillíällen har kunnat ökas till 2000 - 4000 timmar, vilket bety- der mycket ekonomiskt. Det kanske mest positiva som kom ut av dessa försök var emellertid att båda sidorna av kompressorbladen blev lika rena, något som ej varit möjligt tidigare med då förekommande tvättanordningar.No negative effects of injecting liquid into the turbine as this year in operation have been observed. The interval between two washes has been able to be increased to 2000 - 4000 hours, which means a lot economically. Perhaps the most positive thing that came out of these experiments, however, was that both sides of the compressor blades became equally clean, something that had not been possible before with then existing washing devices.

IFig 2 visas insugningshornet 11 rakt framifrån med de fem dysoma 13 ekvidistant placerade ett stycke in i homet, nära gränsen 112.Fig. 2 shows the suction horn 11 straight from the front with the five nozzles 13 equidistantly placed some distance into the housing, near the boundary 112.

I Fig 3, som visar samma vy som Fig 2, har tvättvätska släppts på i dysoma 13.In Fig. 3, which shows the same view as Fig. 2, washing liquid has been released in the nozzles 13.
