The steam released into the atmosphere by the cross sky valve is not an adequate solution for the following reasons: Noise prevention, water losses, thermal heat release into the environment, etc. In this paper, the possibilities and solutions are investigated in order to avoid the HRSG start-up sky venting. For this purpose, the steam quality data at HRSG cold start-up is analysed, and the possibility is examined of discharging the HRSG generated steam at the start-up via a new start-up pipeline into the existing dump condenser, or into the start-up flash tank or into the blowdown tank. The results show that, at the first 3 minutes of cold start-up, the HRSG generated only water, and this water should not be discharged into the HP or IP pipeline headers. The HRSG generates a mixture of water and steam only after 4 minutes from the start-up. For that reason it is not recommended to drain the water-steam mixture at the HRSG start-up into the new start-up pipeline, but it is recommended to drain the water and steam mixture formed during the HRSG start-up into the new start-up flash tank, or into the blowdown tank. The flash tank, and also the blowdown tank, should be appropriately dimensioned"},{"@xml:lang":"sl","#text":"Osnovni namen prispevka je podrobna predstavitev HRSG-ja in analiza možnosti zmanjšanja izpusta generirane pare v atmosfero ob hladnem zagonu. Izpust zagonske pare v atmosfero ni najboljša možna rešitev, saj se s tem poveča zvočna obremenitev okolja, odvod kotlovske vode in toplotne energije v okolje itd. V tem prispevku so analizirane možne rešitve preprečitve odvoda zagonske pare v atmosfero, tako da se mešanica vode-pare ob hladnem zagonu HRSG-ja odvede v novi zagonski parovod, separatorsko posodo ali v posodo za odvodnjavanje. Analizirani pa so bili tudi podatki kvalitete pare ob zagonu HRSG-ja. Rezultati pokažejo, da prve 3 minute HRSG generira samo vodo, ki pa se ne sme odvesti v HP oziroma IP zbiralno kom parovoda. Šele po 4 minutah HRSG prične generirati mešanico vode-pare. Zato se pri hladnem zagonu ne priporoča odvod generirane pare v novi zagonski parovod, ampak da se navedena mešanica vode-pare, ki nastane pri hladnem zagonu HRSG-ja, odvede v separatorsko posodo oziroma v posodo za odvodnjavanje. Navedeni posodi morata biti temu primerno dimenzionirani"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:DOC-885AVSR3","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:DOC-885AVSR3"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:DOC-885AVSR3/42657d42-0132-4eca-85ab-3d658ceec01b/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Mariboru, Fakulteta za energetiko"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:DOC-885AVSR3/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:DOC-885AVSR3"}}}}
