Steam turbine of solar thermal power plant

U sklopu ovog diplomskog rada prikazana je mogućnost iskorištavanja sunčeve energije za proizvodnju električne energije putem toplinske konverzije Sunčeva zračenja. Opisane su različite tehnologije koncentriranja Sunčevog zračenja te sheme postojećih solarnih termoelektrana kao i njihovo trenutno stanje na energetskom tržištu. Na temelju dobivenih podataka o Sunčevom zračenju za područje grada Sinja, proračunata je toplinska shema postrojenja, potrebna površina kolektora te je dimenzioniran spremnik topline. Za odabranu kondenzacijsku parnu turbinu s međuoduzimanjem za regenerativno predgrijavanje napojne vode proveden je proračun svih stupnjeva, te je nacrtan sklopni crtež njenog uzdužnog presjeka. Također, napravljena je tehno - ekonomska analiza isplativosti postrojenja.In this master’s thesis, ways of exploitation of solar energy for the production of electricity through the thermal conversion of the solar radiation have been described. Different solar radiation concentration technologies and existing solar thermal power plants were described as well as their current state on the energy market. Based on the obtained solar radiation data for the area of the city of Sinj, the power cycle scheme of the plant and collector aperture area have been calculated, as well as the heat storage system. For the selected condensing steam turbine with uncontrolled steam bleed for regenerative feed water heating, the calculation of all stages was performed and a sketch drawing of its longitudinal section was drawn. Furthermore, techno – economic analysis of the plant‘s profitability was made
