Claims (6)

1. Fremgangsmåde til regulering af en kortvarig effektstigning hos en dampturbine med en forankoblet fossilfyret gennemløbsdampgenerator med et antal af economiser-, fordamper- og overhedervarmeflader, som danner en strømningsvej, og som er gennemstrømmet af et strømningsmedium, ved hvilken fremgangsmåde strømmen fra strømningsmediet gennem den fossilfyrede gennemløbsdampgenerator øges med henblik på den kortvarige effektstigning hos dampturbinen, hvor der anvendes en entalpi-indstillingsværdi ved udgangen af en fordampervarmeflade som reguleringsstørrelse for fastlæggelsen af indstillingsværdien for strømmen fra strømningsmediet gennem den fossilfyrede gennemløbsdampgenerator, og entalpi-indstillingsværdien reduceres med henblik på den kortvarige effektstigning hos dampturbinen.
2. Fremgangsmåde ifølge krav 1, ved hvilken entalpi-indstillingsværdien reduceres til en på forhånd angivet minimumsentalpiværdi.
3. Fremgangsmåde ifølge krav 2, ved hvilken minimumsentalpiværdien udmåles på en sådan måde, at der i alle belastningstilstande af den fossilfyrede gennemløbsdampgenerator opnås en fuldstændig fordampning af strømningsmediet i fordampervarmefladerne.
4. Fremgangsmåde ifølge et af kravene 1 til 3, ved hvilken højden og/eller varigheden af reduceringen af entalpi-indstillingsværdien bestemmes ved hjælp af den påkrævede effektstigning.
5. Fremgangsmåde ifølge et af de foregående krav, ved hvilken strømningsmedium, der er udtaget i strømningsvejen, med henblik på den kortvarige effektstigning hos dampturbinen, indsprøjtes i området ved en overheder-varmeflade af den fossilfyrede gennemløbsdampgenerator.
6. Fremgangsmåde ifølge et af de foregående krav, ved hvilken varmetilførslen i den fossilfyrede gennemløbsdampgenerator øges.
