Opfindelsen angår en spildvarme-dampgenerator med anvendelse af en kondensator og en kondensatet optagende dampkedel, som indgår i et cirkulationssystem med mindst et faldrør, mindst en varmeflade og mindst et stigrør, og 5 som har et vandrum såvel som et damprum til at udføre adskillelsen af vand-dampblandingen i vand og damp.The invention relates to a waste heat steam generator using a condenser and a condensate receiving steam boiler which is included in a circulation system with at least one drop pipe, at least one heating surface and at least one riser, and 5 having a water space as well as a steam room for effecting the separation of the water-vapor mixture in water and steam.
Til belysning af den kendte teknik skal der i det følgende henvises til den medfølgende tegning.For illustrative purposes of the prior art, reference is made to the accompanying drawings.
10 I det kendte system kan det underafkølede kondensat ved hjælp af en kondensatpumpe 20 pumpes ind i fødevandsbeholderen 7, eventuelt over en ikke vist forvarmer og over en afgasser 38 som vist med stiplede linier. Det afgasse-15 de fødevand bliver på den ene side over en lavtryksføde-vandspumpe 10 og fortrinsvis en economizer 1 ført ind i en lavtrykskedel 8 og på den anden side over en højtryks-fødevandspumpe 13 og en højtrykseconomizer 2 ført ind i en højtrykskedel 9. Der kan også findes flere pumper i 20 begge systemer. Fra lavtrykskedlen 8 bliver vandet over en lavtrykscirkulationspumpe 14 ført ind i en lavtryksfordamper 3, hvorfra lavtryksdampen bliver tilført lavtrykskedlen 8 ad den med stiplede linier viste vej. Dampen bliver tilført lavtryksdelen 18 af en dampturbine 39 25 over lavtryksoverhederen 5.In the known system, the undercooled condensate can be pumped into the feed water tank 7 by means of a condensate pump 20, optionally over a preheater not shown and over an exhaust gas 38 as shown in dotted lines. The degassing feed water is, on the one hand, fed over a low pressure feed water pump 10 and preferably an economizer 1 into a low pressure boiler 8 and on the other hand over a high pressure feed water pump 13 and a high pressure economizer 2 into a high pressure boiler 9. Several pumps can also be found in both systems. From the low-pressure boiler 8, the water over a low-pressure circulation pump 14 is fed into a low-pressure evaporator 3, from which the low-pressure steam 8 is supplied to the low-pressure boiler 8 by the dotted line. The steam is supplied to the low pressure portion 18 of a steam turbine 39 25 over the low pressure supercharger 5.
Fra højtrykskedlen 9 bliver vandet over højtrykscirkulationspumpen 11 tilført højtryksfordamperen 4, fra hvilken dampen føres ind i højtrykskedlen 9 ad den med stiplede 30 linier viste vej. Fra denne kedel bliver dampen dernæst over den stiplede vej ført ind i højtryksoverhederen 6, hvorfra højtryksdampen når ind i højtryksdelen 17 af dampturbinen 39.From the high-pressure boiler 9, the water above the high-pressure circulation pump 11 is supplied to the high-pressure evaporator 4, from which the steam is fed into the high-pressure boiler 9 along the path shown in dotted 30 lines. From this boiler, the steam is then fed over the dotted path into the high pressure supercharger 6, from which the high pressure steam reaches the high pressure portion 17 of the steam turbine 39.
35 I tvangscirkulationssystemet bliver det afgassede vand ved hjælp af fødepumper ført gennem forskellige varmefladesystemer .35 In the forced circulation system, the degassed water is fed through various heating surface systems by means of feed pumps.

Fra US patent skriftet nr. 3 803 846 kendes en spildvarme-dampgenerator af den indledningsvis nævnte art, hvor af-gasseren er anbragt uden for dampkedlen. Denne anordning er pladskrævende.US Patent No. 3,803,846 discloses a waste heat steam generator of the type mentioned in the preamble, where the exhaust gas is located outside the steam boiler. This device is space consuming.

Opfindelsen har til formål at angive et anlæg af den omhandlede art, som er væsentlig simplere og mere økonomisk end det kendte, idet lavtrykskedlens funktion bliver udøvet af fødevandsbeholderen 7.The invention has for its object to provide a plant of the kind in question which is substantially simpler and more economical than the known, in that the function of the low pressure boiler is exercised by the feed water tank 7.
1010
Dette formål opnås ved, at dampkedlen, fortrinsvis en lavtrykskedel, forsynet med en integreret afgasning, udøver en fødevandsbeholders funktion. Derved falder den i det kendte system nødvendige fødevandspumpe bort. Desuden 15 findes der i stedet for den sædvanlige anordning af en fødevandsbeholder og af en lavtrykskedel kun én beholder, der udøver såvel fødevandsbeholderens som lavtrykskedlens funktion.This object is achieved by the fact that the steam boiler, preferably a low pressure boiler, provided with an integrated degassing, performs the function of a feed water container. Thereby, the feed water pump needed in the known system fails. In addition, instead of the usual arrangement of a feed water tank and of a low pressure boiler, there is only one container which performs both the function of the feed water container and the low pressure boiler.
20 Cirkulationen i systemet ifølge opfindelsen kan fortrinsvis finde sted på den i det østrigske patentskrift nr.The circulation in the system according to the invention can preferably take place in the Austrian patent specification no.
392 683 beskrevne måde.392 683 described.
Dampgeneratoren ifølge opfindelsen er desuden karakteri-25 stisk ved, at fødevandet fra fødevandsbeholderen eller dampkedlen, fortrinsvis lavtryksbeholderen, på i og for sig kendt måde tilføres en højtrykseconomizer via en højtryksf ødevandspumpe, og at højtrykseconomizeren på udgangssiden er tilsluttet en højtryksfordamper, fra hvil-30 ken der via en vandudskiller og en højtryksoverheder tilføres damp til en højtryksdel af en dampturbine.The steam generator according to the invention is further characterized in that the feed water from the feed water tank or steam boiler, preferably the low pressure container, is supplied in a known manner by a high pressure economizer via a high pressure feed water pump and the high pressure economizer on the outlet side is connected to a high pressure outlet. For example, steam is supplied to a high pressure portion of a steam turbine via a water separator and a high pressure supercharger.
