KedelophængBoiler Suspension
Teknisk område 5 Opfindelsen angår et kedelophæng til en kedel i et kedelstativ, hvor kedlen er ophængt i en vandret tværbjælke, eksempelvis i et damp kraftværk.TECHNICAL FIELD The invention relates to a boiler suspension for a boiler in a boiler rack, where the boiler is suspended in a horizontal cross beam, for example in a steam power plant.
Teknikkens stade 10 Kedler, der anvendes til frembringelse af vanddamp i dampkraftværker, er sædvanligvis ophængt i en stålramme. Denne stålramme udviser sideværts stræbere og en vandret tværbjælke. Kedlen er fast ophængt på forskellige steder på den vandrette tværbjælke. Ved opvarmning af kedlen udvides denne nedadtil via de øvre fastgørelsessteder. Som følge af denne udvidelse 15 ændres også stillingen for forbindelsesstedet, ved hvilket friskdampledningen er forbundet med kedlen, i lodret retning. For at friskdampledningen, der er forbundet med en turbine, skal kunne tilpasses fleksibelt og svarende til den termiske udvidelse af kedlen, udformes ledningen med flere ekspansionsbøjninger. Disse ekspansionsbøjninger udgør en ulempe ved teknikkens stade, 20 eftersom friskdampledningeme er meget dyre og i væsentlig grad påvirker omkostningerne ved et kraftværk.State of the art 10 Boilers used to produce steam in steam power plants are usually suspended in a steel frame. This steel frame exhibits lateral stretchers and a horizontal crossbeam. The boiler is permanently suspended in various places on the horizontal cross beam. When heating the boiler, it extends downwards via the upper attachment points. As a result of this extension 15, the position of the connection point at which the fresh steam line is connected to the boiler also changes in the vertical direction. In order for the fresh steam line connected to a turbine to be adaptable flexibly and corresponding to the thermal expansion of the boiler, the line is designed with several expansion bends. These expansion bends constitute a disadvantage of the state of the art, since the fresh steam lines are very expensive and substantially affect the cost of a power plant.
Forklaring af opfindelsen 25 Formålet for opfindelsen er at angive et kedelophæng, med hvilket det er muligt at reducere friskdampledningeme, der forbinder kedlen med en turbine, til et nødvendigt minimum for således at minimere udgifterne, der er forbundet med disse ledninger.Explanation of the Invention The object of the invention is to provide a boiler suspension with which it is possible to reduce the fresh steam lines connecting the boiler to a turbine to a necessary minimum so as to minimize the costs associated with these lines.
30 Dette opnås ifølge opfindelsen ved, at kedlen er ophængt med mindst en lodret anbragt hydraulisk cylinder i en tværbjælke, og at der på overfladen af 2 DK 176623 B1 kedlen eller mellem overfladen af kedlen og kedelstativet er anbragt mindst et måleinstrument, der registrerer en lodret udvidelse af kedlen, og som måler den lodrette udvidelse kedlens væg eller den lodrette udvidelse i forhold til kedelstativet, og at mindst et måleinstrument, der registrerer den lodrette ud-5 videlse af kedlen, via en virkeforbindelse er forbundet med mindst den ene lodrette hydrauliske cylinder, således at det hydrauliske ophæng lodret opad-til modvirker en nedad rettet udvidelse.This is achieved according to the invention in that the boiler is suspended with at least one vertical hydraulic cylinder in a transverse beam and that at least one measuring instrument is placed on the surface of the boiler or between the surface of the boiler and the boiler frame. expansion of the boiler, which measures the vertical expansion of the boiler wall or the vertical extension relative to the boiler rack, and that at least one measuring instrument which detects the vertical expansion of the boiler is connected to at least one vertical hydraulic cylinder by means of a working connection. so that the hydraulic suspension vertically upwards to counteract a downward extension.
Så snart kedlen opvarmes og derved udvides nedadtil, hæves den via den 10 hydrauliske lejring. Ved denne kompensation af den nedad rettede udvidelse ændres forbindelsesstedet mellem kedlen og friskdampledningen kun i ringe grad i lodret retning, og ekspansionsbøjninger i friskdampledningerne er ikke længere nødvendige. Fordelagtigt reduceres længden af friskdampledningen . til et minimum på grund af lejringen ifølge opfindelsen, da en større bevægel-15 se kun er mulig i vandret retning.As soon as the boiler is heated and thereby extended downwards, it is raised via the hydraulic bearing. By this compensation of the downward expansion, the connection point between the boiler and the fresh steam line is only slightly altered in the vertical direction, and expansion bends in the fresh steam lines are no longer necessary. Advantageously, the length of the fresh steam line is reduced. to a minimum due to the bearing according to the invention, since a greater movement is possible only in the horizontal direction.
Yderligere udformnings muligheder er angivet i de uselvstændige krav.Further design options are set out in the dependent claims.

30 DK 176623 B1 3 Måde til udførelse af opfindelsen I fig. 1 er der skematisk vist en kedel 2 i et kedelstativ 3 med et kedelophæng 5 1 ifølge opfindelsen. En sådan kedel 2 finder man eksempelvis til frembrin gelse af damp i damp kraftværker. Ifølge opfindelsen er kedlen 2 hydraulisk ophængt i den øvre tværbjælke 4 af kedelstativet 3. Det hydrauliske kedelophæng 1 består af flere cylindre 5, som er anbragt på vandret og lodret måde på tværbjælken 4 og kedlen 2. De lodret anbragte hydrauliske cylindre 5 10 tjener til at modvirke en nedad rettet termisk udvidelse af kedlen 2.1 fig. 1 er udvidelsesretningen 10, som fremkommer ved denne kompensation, antydet med en pil. Desuden styres kedlens udvidelse i vandret retning ved hjælp af de vandret anbragte hydrauliske cylindre 5. Ved hjælp af i fig. 1 ikke viste udvidelsesmåleband eller tryksensorer, som er anbragt på overfladen af ked-15 len 2 eller mellem overfladen af kedlen 2 og kedelstativet 3 og er forbundet via en ej heller vist virkeforbindelse med de hydrauliske cylindre 5, opnås kompensationen forden termiske udvidelse på lodret og på vandret måde.Method for Carrying Out the Invention In FIG. 1, a boiler 2 is shown schematically in a boiler rack 3 with a boiler suspension 5 1 according to the invention. Such a boiler 2 is found, for example, for generating steam in steam power plants. According to the invention, the boiler 2 is hydraulically suspended in the upper transverse beam 4 of the boiler frame 3. The hydraulic boiler suspension 1 consists of several cylinders 5 which are arranged horizontally and vertically on the transverse beam 4 and the boiler 2. The vertically arranged hydraulic cylinders 5 10 counteracting a downwardly directed thermal expansion of the boiler 2.1 FIG. 1, the direction of expansion 10 which results from this compensation is indicated by an arrow. In addition, the expansion of the boiler is controlled in the horizontal direction by the horizontally arranged hydraulic cylinders 5. By means of FIG. 1, pressure gauges or pressure sensors not shown on the surface of the boiler 2 or between the surface of the boiler 2 and the boiler frame 3 and connected via a working connection with the hydraulic cylinders 5 not shown, the compensation for thermal expansion is obtained vertically and in a horizontal way.
Ved den hydrauliske lejring holdes forbindelsesstedet 11 meilem friskdamp-20 ledningen 9 og kedlen 2 i en fast stilling. På dette forbindelsessted 11 opstår der udelukkende vandrette bevægelser, men ikke mere nogen større lodrette bevægelser. Friskdampledningen 9 er forbundet direkte - uden ekspansionsbøjninger - med en dampturbine 6, med hvilken der er forbundet en generator 8 via en aksel 7.At the hydraulic bearing, the connection point 11 is kept between the fresh steam line 9 and the boiler 2 in a fixed position. At this junction 11, only horizontal movements occur, but no more major vertical movements. The fresh steam line 9 is connected directly - without expansion bends - to a steam turbine 6, to which a generator 8 is connected via a shaft 7.
25 1 fig. 2 er der skematisk vist et kedelophæng 1 ifølge opfindelsen til en kedel 2 i en tværbjælke 4 i et kedelstativ 3. Kedelophænget 1 består af flere hydrauliske cylindre 5, som er anbragt både vandret og lodret. De vandrette hydrauliske cylindre 5, af hvilke der er vist seks i fig. 2, er fastgjort på den 30 ene side ved den øvre ende af kedlen 2, den anden side er fastgjort til stive stålrammer 13. Antallet af de lodrette hydrauliske cylindre afhænger af typen DK 176623 B1 4 og størrelsen af kedlen 2, idet antallet her kun eksempelvis er angivet til seks og kan variere. De stive stålrammer 13 er anbragt på flere glidepunkter 14 på kedelstativets 3 tværbjælke 4. Stålrammerne 13 er styret og sikret mod løftning. De vandrette hydrauliske cylindre 5 er fastgjort på den ene side på stål-5 rammen 12, idet den anden side af disse cylindre er anbragt på kedelstativets 3 tværbjælke 4.1 fig. 3 er der eksempelvis vist tre af de vandrette hydrauliske cylindre 5. Også antallet af de vandrette hydrauliske cylindre kan variere alt efter typen og størrelsen af kedlen. De befinder sig hver især mellem to lodrette hydrauliske cylindre 5. De hydrauliske cylindre 5 er via flere 10 ledninger 15, via en hydrauliktrykreguleringsventil 16 pr. ledning 15, forbundet med to hydraulik-trykbeholdere 26, som føder hydrauliksystemet. Hydrau-lik-trykbeholderne 26 efterfyldes efter behov via to kontraventiler 17 og to pumper-18, som drives af en motor 19, fra et olieforråd 20. De lodrette hydrauliske cylindre 5 forsynes med olie via en fælles ledning 15 for at opnå en 15 ensartet lejring (henholdsvis en ensartet ekspansionsudligning) af kedlen i lodret retning. I modsætning hertil er de vandrette cylindre 5 hver især tilsluttet en ledning 15, eftersom der vandret kan opstå forskellige udvidelser på forskellige steder via en forskellig temperaturfordeling i kedlen 2. Hydraulik-trykreguleringsventileme 16 er således indbygget, at strømningsretningen 20 går fra kontraventilerne 17 til cylindrene 5.25 in FIG. 2, a boiler suspension 1 according to the invention is schematically shown for a boiler 2 in a cross beam 4 in a boiler frame 3. The boiler suspension 1 consists of several hydraulic cylinders 5 which are arranged both horizontally and vertically. The horizontal hydraulic cylinders 5, of which six are shown in FIG. 2 is fixed on one side at the upper end of the boiler 2, the other side is fixed to rigid steel frames 13. The number of vertical hydraulic cylinders depends on the type DK 176623 B1 4 and the size of the boiler 2, the number here being only for example, is set to six and may vary. The rigid steel frames 13 are arranged at several sliding points 14 on the cross beam 4 of the boiler frame 3. The steel frames 13 are guided and secured against lifting. The horizontal hydraulic cylinders 5 are fixed on one side of the steel frame 12, the other side of these cylinders being arranged on the cross beam 4.1 of the boiler frame 3. 3, for example, three of the horizontal hydraulic cylinders are shown 5. Also, the number of the horizontal hydraulic cylinders may vary according to the type and size of the boiler. They are each located between two vertical hydraulic cylinders 5. The hydraulic cylinders 5 are via several 10 lines 15, via a hydraulic pressure control valve 16 per unit. line 15, connected to two hydraulic pressure vessels 26 which feed the hydraulic system. The hydraulic pressure vessels 26 are replenished as required via two check valves 17 and two pumps 18, driven by an engine 19, from an oil supply 20. The vertical hydraulic cylinders 5 are supplied with oil via a common conduit 15 to obtain a uniform aligning (a uniform expansion equalization, respectively) of the boiler in the vertical direction. In contrast, the horizontal cylinders 5 are each connected to a conduit 15, since different extensions can occur horizontally at different locations via a different temperature distribution in the boiler 2. The hydraulic pressure control valves 16 are built in such that the flow direction 20 goes from the check valves 17 to the cylinders. 5th
På overfladen af kedlen 2 er der ved overfladen henholdsvis mellem kedlens 2 overflade og kedelstativet anbragt flere måleinstrumenter 23, som registrerer en ved opvarmning eller afkøling opstående udvidelse af kedlen 2. Som 25 måleinstrumenter 23 er eksempelvis udvidelsesmåleband eller tryksensorer tænkelige. Men også andre, ligeværdige måleinstrumenter 23 er tænkelige.On the surface of the boiler 2, several measuring instruments 23 are arranged at the surface, respectively, between the surface of the boiler 2 and the registration of an expansion of the boiler 2. The heating gauge 23, for example, extends measuring tapes or pressure sensors, for example. But other equivalent measuring instruments 23 are also conceivable.
Måleinstrumenterne 23 er med en elektrisk forbindelse 22 forbundet med en hydraulik-trykbegrænsningsventil 21. Hydraulik-trykbegrænsningsventilerne 30 21 befinder sig mellem olieforrådet 20 og - via en ledning 24 - ledningerne 15. De er således indbygget, at strømningsretningen fortrykbegrænsnings- DK 176623 B1 5 ventilerne 21 går fra ledningen 15 - via ledningen 24 - til olieforrådet 20. Med hydraulik-trykbegrænsningsventilerne 21 er derf.eks. forbundet motorer, som indstiller trykket i systemet i afhængighed af måleværdierne for måleinstrumenterne 23. I stedet for motorerne 25 er imidlertid også proportionalmagne-5 ter tænkelige.The measuring instruments 23 are connected by an electrical connection 22 to a hydraulic pressure limiting valve 21. The hydraulic pressure limiting valves 30 21 are located between the oil supply 20 and - via a conduit 24 - the conduits 15. They are built in such a way that the flow direction pressure limiting valves DK 176623 B1 5 21 goes from line 15 - via line 24 - to the oil supply 20. With the hydraulic pressure limiting valves 21, e.g. connected motors which adjust the pressure in the system depending on the measurement values of the measuring instruments 23. However, instead of the motors 25, proportional magnets 5 are also conceivable.
Virkemåden for det hydrauliske kedelophæng 1 er som følger: På grund af vægten af kedlen 2 står de lodrette hydrauliske cylindre 5 under et bestemt tryk. De optager vægten af kedlen 2. Hvis kedlen 2 opvarmes og derved ud-10 vides nedad, stiger måleværdien af måleinstrumentet 23, som står virkeforbindelse med hydraulikbegrænsningsventilen 21. Stiger nu trykket i det pågældende hydrauliksystem og dermed i de lodrette hydrauliske cylindre 5, hæves kedlen 2. Ved hævningen af kedlen 2 falder måleværdien af måleinstrumentet 23 igen så langt som den var i udgangsstillingen. Trykregulerin-15 gen i de lodrette hydrauliske cylindre 5 opnås via hydraulik- trykbegrænsningsventilen 21; med hydrauliktrykreguleringsventilen 16 indstilles det maksimale systemtryk. Tyder en stigende måleværdi for måleinstrumentet 23 på, at trykket i de lodrette hydrauliske cylindre stiger, og kedlen derved skal hæves, indstilles hydraulik-trykbegrænsningsventilen 21 således 20 via forbindelsen 22 og motoren 25, at systemtrykket øges, og det forhåndenværende driftstryk øges via trykket, der skal indstilles til. Derpå tappes der ved hydrauliktrykbegrænsningsventilen 21 olie via ledningen 24 i olieforrådet 20 lige indtil trykket, der skal indstilles til, opnås.The operation of the hydraulic boiler suspension 1 is as follows: Due to the weight of the boiler 2, the vertical hydraulic cylinders 5 are under a certain pressure. They take up the weight of the boiler 2. If the boiler 2 is heated and thereby extended downwards, the measuring value of the measuring instrument 23, which is in communication with the hydraulic limiting valve 21. increases, now the pressure in the relevant hydraulic system and thus in the vertical hydraulic cylinders 5 is raised. 2. When the boiler 2 is raised, the measuring value of the measuring instrument 23 drops again as far as it was in the initial position. The pressure control in the vertical hydraulic cylinders 5 is achieved via the hydraulic pressure limiting valve 21; with the hydraulic pressure control valve 16, the maximum system pressure is set. If an increasing measurement value of the measuring instrument 23 indicates that the pressure in the vertical hydraulic cylinders increases and the boiler must be raised, the hydraulic pressure limiting valve 21 is thus adjusted via the connection 22 and the motor 25 to increase the system pressure and the existing operating pressure is increased via the pressure, to be set to. Thereafter, oil is drained at hydraulic pressure relief valve 21 via line 24 in oil reservoir 20 until the pressure to be set is reached.
25 Via denne mekanisme stiger trykket i de lodrette hydrauliske cylindre 5 og kedlen 2. Kedlen 2 hæves indtil, henholdsvis trykket øges indtil måleinstrumentets 23 måleværdi igen er indstillet til værdien for begyndelsespositionen.25 Through this mechanism, the pressure in the vertical hydraulic cylinders 5 and the boiler 2. The boiler 2 is raised until, respectively, the pressure is increased until the measuring value of the measuring instrument 23 is again set to the value for the initial position.
Derpå holdes trykket i ledningerne 15, 24 og de lodrette hydrauliske cylindre 5 konstant henholdsvis hydraulik-trykreguleringsventilen 16 åbnes så vidt via 30 forbindelsen 22 og motoren 25, at gennemstrømningen svarer til gennemstrømningen i hydraulik-trykreguleringsventilen 16.Thereafter, the pressure in the lines 15, 24 and the vertical hydraulic cylinders 5 are kept constant, respectively the hydraulic pressure control valve 16 is opened so far via the connection 22 and the engine 25 that the flow corresponds to the flow in the hydraulic pressure control valve 16.
DK 176623 B1 6DK 176623 B1 6
Ved afkøling af kedlen 2 og en nødvendig sænkning af kedlen 2 via de hydrauliske cylindre 5 finder det netop beskrevne forløb sted modsat retning, dvs. med modsat fortegn. Trykket i de lodrette cylindre sænkes da via det 5 indstillede lavere tryk i hydrauliktrykbegrænsningsventilen 21.Upon cooling of the boiler 2 and a necessary lowering of the boiler 2 via the hydraulic cylinders 5, the process just described takes place in the opposite direction, ie. with opposite sign. The pressure in the vertical cylinders is then lowered via the lower pressure set in the hydraulic pressure limiting valve 21.
Ved denne hydrauliske regulering af kedelophænget 1 ændres forbindelsesstedet mellem kedlen 2 og friskdampledningen (ikke vist i fig. 2) kun i ringe grad i lodret retning, og de nødvendige ekspansionsbøjninger, som ved tek-10 nikkens stade udligner udvidelsen i lodret retning, bortfalder.By this hydraulic control of the boiler suspension 1, the connection point between the boiler 2 and the fresh steam line (not shown in Fig. 2) is only slightly altered vertically, and the necessary expansion bends, which at the state of the art equalize the extension in the vertical direction, lapse.
Foruden den lodrette lejring via hydrauliske cylindre 5 findes der en vandret lejring. Denne vandrette lejring er nødvendig, da kedlen 2 også udviser en udvidelse i vandret retning. Mellem hver to lodrette hydrauliske cylindre 5 er 15 der eksempelvis, således som det allerede er beskrevet ovenfor, anbragt en vandret hydraulisk cylinder 5. Denne regulering aftrykket i denne vandrette hydrauliske cylinder 5 og dermed reguleringen af en vandret udligning af kedlens 2 lejring ved en udvidelse af kedlen 2 er tilvejebragt svarende til den ovenfor beskrevne lodrette lejring af kedlen 2.1 det øvre område af kedlen 2 20 henholdsvis mellem kedlen 2 og kedelstativet 3 er der fortrinsvist i nærheden af den lodrette ophængning af kedlen 2 via de lodrette cylindre 5 anbragt måleinstrumenter 23, som registrerer en vandret udvidelse af kedlen 2. Trykket i ledningerne 15, 24 og de lodrette hydrauliske cylindre 5 reguleres via hydrau-lik-trykbegrænsningsventilen 21, og med hydrauliktrykreguleringsventilen 16 25 indstilles det maksimale systemtryk. Hvis en måleværdi af måleinstrumentet 23 ændrer sig, justeres trykket tilsvarende i systemet ved hydraulik-trykreguleringsventilen 21 via en forbindelse 22 og en motor 25 for at reducere eller øge trykket i de vandrette cylindre 5. Denne proces styrer den vandrette lejring lige indtil måleinstrumenternes måleværdier igen angiver en neu-30 tral værdi. Systemet består af ledninger 15, 24 og de vandrette cylindre 5.In addition to the vertical bearing via hydraulic cylinders 5, there is a horizontal bearing. This horizontal bearing is necessary as the boiler 2 also exhibits an extension in the horizontal direction. Between each of two vertical hydraulic cylinders 5, for example, as already described above, is arranged a horizontal hydraulic cylinder 5. This adjustment the pressure in this horizontal hydraulic cylinder 5 and thus the regulation of a horizontal equalization of the bearing of the boiler 2 by an extension. of the boiler 2 is provided corresponding to the vertical bearing of the boiler 2.1 described above. The upper area of the boiler 2 20, respectively, between the boiler 2 and the boiler frame 3 is preferably in the vicinity of the vertical suspension of the boiler 2 via the measuring instruments 23 arranged in the vertical cylinders 5. which records a horizontal expansion of the boiler 2. The pressure in the lines 15, 24 and the vertical hydraulic cylinders 5 is controlled via the hydraulic pressure limiting valve 21, and with the hydraulic pressure control valve 16 25 the maximum system pressure is set. If a measuring value of the measuring instrument 23 changes, the pressure is adjusted accordingly in the system by the hydraulic pressure control valve 21 via a connection 22 and a motor 25 to reduce or increase the pressure in the horizontal cylinders 5. This process controls the horizontal bearing until the measuring values of the measuring instruments again. indicates a neutral value. The system consists of lines 15, 24 and the horizontal cylinders 5.

Trykket holdes da via hydraulik-trykreguleringsventilerne 16 på det af måleværdien forudbestemte niveau.The pressure is then maintained via the hydraulic pressure control valves 16 at the level determined by the measured value.
Ifig. 3 vises det hydrauliske kedelophæng 1 ifølge opfindelsen ved en U-5 formet kedel, som består af to lodrette kedeldele og et ikke svejst forbindelsessted 12. Igen overvåges den termiske udvidelse via udvidelsesmålebånd eller tryksensorer, som ikke er vist i fig. 3 og er anbragt på overfladen af kedlen 2, og som står i virkeforbindelse, der heller ikke er vist, med de hydrauliske cylindre 5. Den hydrauliske lejring styres ved begge dele både lodret og 10 vandret via cylindrene 5 (udvidelsesretningen 10 er antydet med pile fig. 3), så at forbindelsesstedet 11 mellem kedlen 2 og friskdampledningen 9 udelukkende kan bevæge sig i vandret retning og kun ringe grad i lodret retning.In FIG. 3, the hydraulic boiler suspension 1 according to the invention is shown by a U-5 boiler consisting of two vertical boiler parts and a non-welded connection point 12. Again, the thermal expansion is monitored via expansion measuring tapes or pressure sensors not shown in FIG. 3 and located on the surface of the boiler 2, which are in working communication, not shown either, with the hydraulic cylinders 5. The hydraulic bearing is controlled at both parts both vertically and 10 horizontally via the cylinders 5 (the expansion direction 10 is indicated by arrows Figure 3), so that the connection point 11 between the boiler 2 and the fresh steam line 9 can move only in the horizontal direction and only slightly in the vertical direction.
Af hensyn til bedre overskuelighed er den tilsluttede dampturbine ikke vist i fig. 3, ligesom også kedelstativet og tværbjælken, i hvilken kedlen erop-15 hængt, mangler. Ved den U-formede kedel 2 er det vigtigt, foruden overvågningen af de to lodrette kedeldele, at overvåge udvidelse af det ikke svejste forbindelsessted 12 via ikke viste udvidelsesmålebånd eller tryksensorer. En termisk ændring i området for det ikke svejste forbindelsessted 12 ledes via en ligeledes ikke vist virkeforbindelse til de to kedeldeles vandret anbragte 20 cylindre 5, som sørger for en tilsvarende udligning, for således optimalt at sikre, at der ikke opstår nogen forskydning i området for det ikke svejste forbindelsessted 12.For better clarity, the connected steam turbine is not shown in FIG. 3, as well as the boiler rack and crossbeam, in which the boiler is hung, is missing. At the U-shaped boiler 2, it is important, in addition to monitoring the two vertical boiler parts, to monitor expansion of the non-welded connection point 12 via expansion gauges or pressure sensors not shown. A thermal change in the region of the non-welded junction site 12 is conducted via a similar connection shown to the two boiler parts horizontally arranged 20 cylinders 5, which provide a corresponding equalization, so as to optimally ensure that no displacement occurs in the region of the non-welded connection point 12.
