Modeliranje i parametarska analiza rada ložišta energetskog kotla

  • U radu su prikazani odabrani rezultati parametarskih proračuna izvedenih na osnovu numeričke simulacije procesa u ložištu za sagorevanje ugljenog praha energetskog kotla TENT-A2 210 MWe, sa odvođenjem šljake u čvrstom stanju i tangencijalnim rasporedom gorionika. Kao radni parametri karakteristični za pogonsko stanje ložišta, odabrani su finoća mlevenja ugljenog praha i kvalitet uglja. U parametarskoj analizi je posmatrano pet režima rada ložišta. Simulacija je izvedena na osnovu 3D matematičkog modela procesa, razvijenog za simulaciju procesa u ložištima industrijskih razmera. Prikazani su rezultati simulacija i analiziran uticaj odabranih parametara na konverziju čestica ugljenog praha usled sagorevanja, temperaturu dimnog gasa i koncentraciju ugljen-dioksida u ložištu, kao i flukseve toplotnog zračenja na ekranskom zidu. Naglašena je potencijalna primena matematičkog modeliranja procesa u ložištima energetskih kotlova za dijagnostiku i predviđanje pogonskih stanja i situacija.
