REKONSTRUKCIJA PARO – PROIZVODNOG ENERGETSKOG POSTROJENJA

U diplomskom radu izrađena je rekonstrukcija paro-proizvodnog postrojenja, a pod time spada analiza usporedbe četiri vrste goriva, toplinski proračun generatora pare i proračun čvrstoće pojedinih dijelova. U početku diplomskog rada je opisan način rada takvog postrojenja sa svim njegovim glavnim djelovima. Nakon uvodnog dijela napravljena je analiza utjecajnih čimbenika na iskoristivost generatora pare i potrošnju goriva. Za svaku vrstu goriva dobiveni su rezultati koji su vidljivi u tablicama i dijagramima. Odabirom jedne vrste goriva tj. prirodnog plina (teorijskog sastava) napravljen je toplinski proračun generatora pare i proračun čvrstoće. Rezultati pokazuju temperature koje se javljaju u generatoru pare i količine topline koje su potrebne za proizvodnju pregrijane pare. Izračunate su dimenzije pojednih dijelova generatora pare te njihova učinkovitost. Na kraju je izrađen generalni nacrt generatora pare, shema proizvodnje pare te nacrt uljnih cjevovoda gorionika.The focus of this thesis is the reconstruction of a steam-generating plant. This thesis includes the analysis and comparison of four different types of fuel as well as the calculations of a steam generator’s capacities. The beginning of the thesis includes the description of such a plant as well as a list of all its crucial parts. Following the introductory part, this thesis includes an analysis of all factors influencing the steam generator’s usability and consumption of fuels. Tables and diagrams included in this thesis contain results obtained from the analysis of the four fuel types. After choosing only one type of fuel i.e. natural gas (of a hypothetical composition), the calculations of a steam generator’s capacities as well as strength calculations were derived. Results show temperatures occurring within the generator and the amount of heat necessary to produce overheated steam. Dimensions of several parts of the generator as well as their efficiency have also been calculated. Finally, blueprints of the steam generator, schematics of the steam-production pattern as well as the pipeline diagrams for the steam generator have been drawn up
