Claims (7)

1. Tvangsgennemløbsdampgenerator (1) med et brændkammer med en omgivende væg (2), der i det mindste delvist er dannet af gastæt svejsede damp-generatorrør, hvor der inden i brændkammeret er anbragt to indervægge (4, 8), der i det mindste delvist er dannet af yderligere dampgeneratorrør, hvilke indervægge er koblet efter hinanden på strømningsmediumsiden via en mellemopsamlingsindretning (6), hvor der i tvangsgennemløbsdampgeneratoren (1) er tilvejebragt en foropvarmningsindretning (16), som tilvejebringer forskellige varmeindførsler i forskellige mediestrømme, således at strømningsmediet, når tvangsgennemløbsdampgeneratoren er i drift, ved en indgang (12) af in-dervæggen (4), der er koblet foran mellemopsamlingsindretningen (6), har en lavere temperatur end strømningsmediet ved en indgang (10) af den omgivende væg (2), og hvor temperaturen af strømningsmediet, når tvangsgennemløbsdampgeneratoren er i drift, ved indgangen (12) af indervæggen (4), der er koblet foran mellemopsamlingsindretningen (6), er reduceret så meget, at der i mellemopsamlingsindretningen (6) forhindres en tofaseblanding af vand og damp.
2. Dampgenerator (1) ifølge krav 1, hvor brændkammeret har en fluidbed-op-fyringsindretning.
3. Dampgenerator (1) ifølge et af de foregående krav, hvor der foran mellemopsamlingsindretningen (6) er indkoblet to indervægge (4) på strømningsmediumsiden, der er anbragt symmetrisk i brændkammeret og i det mindste delvist er dannet af yderligere dampgeneratorrør.
4. Dampgenerator (1) ifølge krav 1, hvor der foran indgangen afen foropvarmningsindretning (18) på strømningsmediumsiden forgrener sig en brodannelsesledning (22), som udmunder i indgangen (12) af en indervæg (4), der er koblet foran mellemopsamlingsindretningen (6), eller indervæggene (4), der er koblet foran mellemopsamlingsindretningen (6).
5. Dampgenerator (1) ifølge krav 4, hvor brodannelsesledningen (22) omfatter en gennemstrømningsreguleringsventil (28).
6. Dampgenerator (1) ifølge krav 1, hvor der foran indgangene (12) af inder-væggen (4) eller indervæggene (4) på strømningsmediumsiden er koblet en første foropvarmningsindretning (32) og foran indgangen (10) af den omgivende væg (2) på strømningsmediumsiden er koblet en anden foropvarmningsindretning (18) hvor den første foropvarmningsindretning (32) har en mindre varmeindførsel end den anden foropvarmningsindretning (18).
7. Dampgenerator ifølge krav 1, hvor der foran indgangene (12) af indervæg-gen (4) eller indervæggene (4) og foran indgangen (10) af den omgivende væg (2) på strømningsmediumsiden er koblet en første foropvarmningsindretning (18), og hvor der foran indgangen (10) af den omgivende væg (2) på strømningsmediumsiden serielt med den første foropvarmningsindretning (18) er koblet en anden foropvarmningsindretning (32).
