20.500.12556/RUL-95466 Utilizator za proizvodnjo zagonske pare parnih postrojenj HRSG for cold start-up of steam power plants V diplomski nalogi obravnavamo problematiko zagonov večjih parnih postrojenj. Zaradi velikih mas postrojenja in posledično velike termične vztrajnosti je potrebno hladne zagone parnih postrojenj izvajati po določenih in standardiziranih postopkih segrevanja z zagonsko paro. V obravnavanem primeru zagotavljamo zagonsko paro z utilizatorjem, ki je prigrajen odprtemu plinskemu procesu. V nalogi smo predstavili merilne metode in postopek izvedbe prevzemnih meritev ter analizirali izmerjene vrednosti masnih in energijskih tokov na robovih utilizatorja in jih primerjali z numerično izračunanimi. Rezultati meritev se ujemajo z rezultati numeričnega modela. Izkaže se, da prevzemne meritve potrdijo pogodbo zajamčene tehnološke vrednosti zagonske pare. In this diploma thesis, we deal with issues about cold start-ups of larger steam power plants. Due to a great mass of the power plant and consequently greater thermal perseverance cold start-ups must be executed explicitly by certain standardized procedures. In considered case start-up steam is produced with HRSG which is attached to the gas turbine. In written assignment, we introduced measurement methods with procedures defining how to carry out the takeover measurements. We also analysed measured quantities of mass and energy currents on the edge of HRSG system and compared them with numerically computed quantities. The outcome of measurements matches with the results of numerical model which validates guarantee-contract of technological start-up steam parameters. parna postrojenja zagon parnih postrojenj utilizator plinsko-parni proces zagonska para prevzemne meritve Steam power plants Cold start-up of steam power plants HRSG Gas-steam process Start-up steam Takeover measurements true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2017-09-20 14:43:32 2017-09-20 14:43:32 2022-08-10 06:23:09 0000-00-00 00:00:00 2017 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 200395 856.pdf 856.pdf 1 70483F019E407162D5DE04B9DF6DBBC2 8dffb361ae4cba1348c4d1a2c22bace22be0b35b996441d8633e931f98318c67 c33923e8-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/cc153644-f9cb-4c90-be92-7eec856bec8b https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=104070 Fakulteta za strojništvo 0 0 0
