20.500.12556/DKUM-73114 Tehniško - tehnološka analiza obratovanja soproizvodnje toplote in električne energije za ogrevanje zemeljskega plina na merilno regulacijski postaji diplomsko delo Technical - technological operating analysis of combined heat and power production unit for natural gas heating in measuring regulatory station Diplomska naloga zajema področje ogrevanja zemeljskega plina na merilno regulacijski postaji z izkoriščanjem odvečne toplote soproizvodnje toplote in električne energije. V nalogi je predstavljeno, kako se s spreminjanjem temperature povratnega toka grelne tekočine spreminja izkoristek soproizvodnje toplote in električne energije. Višja, kot je temperatura povratne vode, nižji je izkoristek naprave. Naloga analizira tudi možnost vgradnje večjega toplotnega prenosnika v merilno regulacijsko postajo in ekonomsko upravičenost takšne investicije. Ta se je izkazala za neupravičeno, saj je povračilna doba stroškov investicije predolga. The presented work is in the field of heating of natural gas in measuring regulatory station with exploitation of excess heat from combined heat and power production unit. Changing of combined heat and power production efficiency with changing temperatures of return heating water is presented in this work. Higher the temperature of return heating water the lower the device efficiency. The work analyses the possibility of installing a larger heat exchanger in measuring regulatory station too, as well as economic justification of such an investment depending on costs. This possibility was estimated as unjustified due to too long recovery of investment costs. ogrevanje soproizvodnja toplote in električne energije toplota prenosnik zemeljski plin heating combined heat and power production heat exchanger natural gas true true false [M.
