Toplifikacijsko postrojenje na drvnu biomasu

Tema ovoga diplomskog rada je toplifikacijsko postrojenje na drvnu biomasu. U diplomskom radu izrađena je energetska analiza objekata NP Plitvička jezera. Određene su potrebe objekata za toplinskom i električnom energijom te je izvršen pregled postojećeg stanja opskrbe energijom. Postojeći sustavi za grijanje i pripremu tople vode su opisani i pregledane su njihove potrošnje goriva. Dat je pregled goriva iz biomase te je detaljnije prikazana drvna biomasa koja i je predmet ovoga rada. Pregledane su moguće varijante energenata iz drvne biomase te je opisana tehnologija pripreme i izgaranja. Taj dio rad se temeljio na dostupnosti energenta u bližem okruženju NP Plitvička jezera pa su izračunate dostupne količine i cijene odabranog energenta. U radu su opisane i moguće tehnologije kogeneracijskih postrojenja te je odabran koncept energane koja udovoljava energetskim potrebama NP Plitvička jezera. Prikazani su i opisani dijelovi energane te princip rada energane. Izračunati su osnovni podaci poput potrebne snage, potrošnje goriva, dobivenih količina energije te iskoristivosti procesa.The theme of this graduate thesis is a district heating plant that uses wood biomass as fuel. In this graduate thesis an energy analysis of objects in NP Plitvička jezera has been conducted. The needs for heating and electric energy are determined and a review of existing state of energy supply has been made. Current heating and hot water systems are described and a review of their fuel consumption has been made. A review of biomass fuels is given and also a detailed overview of wood biomass fuels that is in fact the topic of this graduate thesis. Possible versions of fuels from wood biomass and the technologies of their preparation are also described and reviewed. That part of this thesis was written based on availability of wood biomass energy in closer surroundings so available amounts and prices of wood biomass have been calculated. Possible combined heat and power generation plants technologies are described and a concept of a CHP plant that meets the needs of energy demands in NP Plitvička jezera has been chosen. Parts of the CHP plant and the work process of the plant of are reviewed and described. Basic data as required power, fuel consumption, produced energy amounts and process efficiency have been calculated
