Project of combined cycle power plant

U ovome diplomskome radu razrađen je projekt dimenzioniranja kombinirane plinskoparne termoelektrane po uzoru na termoelektranu koja se nalazi u Hrvatskom zagorju. Ulazni podatak za početak projektiranja bio je dobiti izlaznu snagu od 80 MWel. Elektrana se sastoji od dva bloka koji mogu raditi neovisno jedan o drugome, a svaki blok se sastoji od plinskog dijela koji proizvodi 30 MWel i parnog dijela koji proizvodi još dodatnih 10 MWel. Plinski i parni dio postrojenja povezani su pomoću utilizatora u kojem ispušni dimni plinovi iz plinskog procesa predaju svoju toplinu vodi odnosno pari koja se koristi u parnom dijelu procesa. Prvi dio rada opisuje princip rada plinskog postrojenja, parnog postrojenja i na kraju kombiniranog postrojenja. Zatim slijedi kratki opis kombinirane termoelektrane koja se nalazi u Hrvatskoj „KTE Jertovec“. U drugom dijelu rada slijedi analitički proračun kombinirane termoelektrane koji se sastoji od tehničkog opisa energetskog sustava, proračuna energetske bilance plinskog dijela postrojenja, proračuna energetske bilance parnog dijela procesa, dimenzioniranja ogrjevnih površina utilizatora te generalni plan utilizatora i dispozicijskog smještaja elektrane.In this masters thesis, a design proces for a combined cycle thermal power plant was elaborated. The plant parameters are based on existing thermal power plant in Croatia. The input data for the start of the design calculation was 80 MWel total power output. The power plant consists of two blocks that can operate independently of each other. Each block consists of a gas turbine part that produces 30 MWel and a steam turbine part that produces an additional 10 MWel. The gas and steam part of the plant are connected by a heat recovery steam generation where the exhaust fumes from the gas turbine deliver heat to the water and the steam which are then used in the steam turbine part of the process. The introduction part describes the operating principle of the gas turbine power plant, the steam turbine power plant and finally the working principle of the combined cycle power plant. Then a short description of the combined cycle thermal power plant located in Croatia "KTE Jertovec" follows. The second part of thesis is based on the analytical thermal calculation of a combined cycle power plant, which consists of technical description of the energy system, the energy balance calculation of the gas turbine part, the energy balance calculation of the steam turbine, the heat recovery steam generator sizing calculation, the general steam generator plan and the layout drawing of the power plant
