Energy efficiencies and losses comparison of steam turbines from two power plants

U prvom dijelu rada napravljen je proračun snage, energijskih gubitaka, stupnja iskoristivosti i energijskih gubitaka po jedinici snage za turbine termoelektrane Kostolac, Srbija nazivne snage 348 MW. Termoelektrana Kostolac ima tri kućišta: niskotlačno, srednjetlačno i visokotlačno. Nakon toga napravljen je proračun istih parametara za termoelektranu Sinkiang, Kina nazivne snage 330 MW. Termoelektrana Sinkiang također ima tri kućišta. Zatim je napravljena usporedba te dvije termoelektrane na temelju dobivenih podataka. Termoelektrane su prvo uspoređivane po kućištima, a potom i po ukupnim iznosima za svaki od gore navedenih parametara.In first part of this final thesis we made calculations for power, energy loss, degree of usability and energy loss by unit of power for turbines of thermal power plant Kostolac, Srbija that has nominal power of 348 MW. Thermal power plant Kostolac has 3 housings: lowpressure, middlepressure and highpressure. After that, calculations on same parametars were made for thermal power plant Sinkiang, China that has nominal power of 330 MW. Thermal power plant Sinkiang also has three housings. Then comparations between two power plants were made based on calculated data. Thermal power plants were first compared by housings and then by total amounts for all of parametars given abov
