Description

• Oppfinnelsen angår et energiforsørgingssystem for flytende gass med dieselmotordrift, med et flytendegjørings-anlegg for den gass som oppstår i lagertankene og som drives av et motorgeneratoraggregat, en dampkjel for den varmemengde som fjernes for utnyttelse av denne varmemengde og videre med et dampturbin-generatoraggregat for fremstilling av elektrisk energi for det elektriske nett ombord.
Dette kjente prinsipp for et energiforsørgingssystem for tankskip med flytende gass er for tiden det mest økono-miske. En ulempe er imidlertid de høye investeringskostnader da sikkerhetsforskriftene krever et overskudd i flytendcgjør-ingsanlegget , dvs. at det må foreligge to flytendegjørings-anlegg hvor hvert anlegg må ha den fulle flytendegjørings-effekt og at det videre må foreligge et motor-generatoraggregat for drift av hvert anlegg. Det kreves videre at hvert flytendegjøringsanlegg skal kunne flytendegjøre den maksimalt mulige mengde fordampet gass.
Oppfinnelsen tar sikte på å frembringe et energifor-sørgingssystem for tankskip med flytende gass av den innled-ningsvis beskrevne type, men som krever betydelig lavere investeringskostnader. Denne oppgave løses ifølge oppfinnelsen ved de i den karakteriserende del av patentkravet angitte trekk.
En utførelse av oppfinnelsen beskrives i det etterføl-gende på grunnlag av tegningen som skjematisk viser et energi-forsørgingssystem ifølge oppfinnelsen for et tankskip for flytende gass.
Energiforsørgingssystemet for gasstankere med flytende gass har en dieselmotor 10, en dampkjel 11 for varmeopptak,
et flytendegjøringsanlegg 12, et dampturbin-generatoraggregat 13-14 for et elektrisk nett 15 ombord, og et motor-generatoraggregat 16-17 for flytendegjøringsanlegget 12. For de mange tanker for flytende gass ombord på skipet er kun en tank 18 inntegnet.
Dieselmotoren 10 driver en propeller 19 for gasstank-erens fremdrift. Dieselmotorens 10 varme forbrenningsgass tilføres via en ledning 20 dampkjelen 11 som fremstiller dam-pen for dampturbin-generatoraggregatet 13-14. Aggregatets 13-14 dampturbin 13 er en totrykks turbin med en tilførsel for kjelens 11 damp via en ledning 21 og en tilførsel via en ledning 22. Dampturbinens 13 damputtak kondenseres i en kondensator 23 med sjøvannskjøling. Kondensvannet føres via en ledning 24 til kjelen 11. Som kjølevann for kondensatoren 23 benyttes sjøvann som pumpes fra en pumpe 25 gjennom kondensatoren og tilbake til sjøen 26.
Aggregatets 13-14 generator 14 forsørger det elektriske nett 15 ombord via en hovedbryter 30, en nettbryter 31 og minst én transformator 32.
Generatoren i motor-generatoraggregatet 16-17, som kan være et dieselmotor-genereatoraggregat, leverer den elektriske energi for flytendegjøringsanlegget 12. En kompressor 33 i flytendegjøringsanlegget 12 suger den ved varmepåvirkning fordampede gass fra lagertankene 18 via en ledning 3 4 og kom-primerer denne slik at den på kjent måte flytendegjøres og som gass igjen tilføres lagertankene via en ledning 35. Kom-pressoren 33 drives av en elektromotor 36 som via en hovedbryter 37 og en motorbryter 38 tilføres energi fra motoraggre-gatets 16-17 generator 17. Forbrenningsgassen for motorgene-ratoraggregatets 16-17 dieselmotor 16 tilføres kjelen 11 via en ledning 39 som også utnytter denne varme til dampefrem-stilling. Istedenfor en dieselmotor kan aggregatet 16-17 ha en annen drivanordning som er egnet for flytende eller gass-formet drivstoff. Drivanordningen kan også være en gasstur-bin .
Kjelen 11 har en ekstra fyringsanordning 40 som tilføres fordampet gass fra lagertankene 18 via en ledning 41 med en ventil 42 og en pumpe 43. Den ekstra fyringsanordning kan også være tilordnet en eller flere separate damp-kjeler .
Kjelen med ekstra fyringsanordning 40 og også dampturbin-generatoraggregatet 13-14 er dimensjonert for det fulle effektforbruk for både det elektriske nett 15 ombord og flytendegjøringsanlegget 12. Tilleggsforbrenningsanordningen er i seg selv dimensjonert så stor at også denne kan forbrenne den maksimalt mulige dampmengde som oppstår i lagringstankene .
Energiforsørgingssystemet virker som følger.
Ved normal drift ombord på tankskipet leveres energien for flytendegjøring av den damp som oppstår i lagringstankene fra motor-generatoraggregatet 16-17. Hovedbryteren 37 og motorbryteren 38 er herved lukket. Hovedbryteren 30 og nettbryteren 31 er likeledes lukket slik at det elektriske nett 15 ombord mates fra dampturbrin-generatoraggregatets 13-14 generator 14. Da en bryter 45 er åpen, er driften av flytendegjøringsanlegget 12 og det elektriske nett 15 ombord adskilt fra hverandre.
Oppstår en forstyrrelse i motor-generatoraggregatet 16-17 slik at flytendegjøringsanlegget 12 faller ut på grunn av manglende energitilførsel, åpnes hovedbryteren 3 7 og bry-teren 45 lukkes slik at dampturbin-generatoraggregatet 13-14 nå tilfører elektrisk energi både til det elektriske nett 15 ombord og flytendegjøringsanlegget. Herved åpnes ventilen 42 delvis slik at en del av den damp som oppstår i lagringstankene 18 tilføres tilleggsfyringsanordningen 40 i kjelen 11 via pumpen 4 3 og det således utvikles en større dampmengde for å kunne dekke dampturbin-generatoraggregatets 13-14 større dampforbruk.
Dersom begge aggregater 13-14 og 16-17 faller ut på grunn av havari slik at det for flytendegjøringen av den fordampede gass ikke er elektrisk energi til rådighet, åpnes ventilen 42 helt og all den damp som oppstår i lagringstankene 18 forbrennes i tilleggsforbrenningsanordningen 40. En treveisventil 52 i damptilførselsledningen 21 vendes herved mot en ledning 53 til kondensatoren 23 slik at hele den dampmengde som oppstår i kjelen 11 tilføres kondensatoren og kondenseres her. En annen mulighet består i at hele den damp som utvikles blåses direkte ned i sjøvannet 26 via treveis-ventilen 52 og en ledning 54.
