20.500.12556/DKUM-67635 Scale-up research in a dual fluidized bed gasification process A successful co-gasification of plastics and biomass was achieved in the 100 kW dual fluidized bed (DFB) gasification pilot plant. The results of a pilot plant experiment were used as a sound basis for scale-up prediction to 750 kW semiindustrial DFB plant. By an eightfold increase of mass and heat flows a rather simplified co-gasification process was predicted. Namely, the losses occurring in gasification plants are expected to be relatively smaller in larger plants. The effect of decreased losses was studied with an equilibrium model. Three different situations were simulated with the following fixed values of losses: 70 kW, 115 kW and 160 kW. The model showed an increase in fuel conversion when losses were reduced. V 100 kW pilotnem uplinjevalniku z dvojnim lebdečim slojem (DFB) je bilo doseženo uspešno skupno uplinjanje plastike in biomase. Rezultati eksperimenta na pilotnem uplinjevalniku so bili uporabljeni kot dobra osnova za napoved procesa v 750 kW polindustrijskem DFB uplinjevalniku. Z osemkratnim povečanjem masnih in toplotnih tokov je nastala poenostavljena shema procesa skupnega uplinjanja obeh goriv. Izgube naj bi bile pri večjih uplinjevalnikih relativno manjše. Z ravnotežnim modelom je bil preučevan učinek zmanjševanja izgub. Predvidene so bile tri različne situacije z naslednjimi vrednostmi izgub: 70 kW, 115 kW in 160 kW. Z ravnotežnim modelom je bilo ugotovljeno, da zmanjševanje izgub vodi do večje pretvorbe goriva. gasification simulation dual fluidized bed reactor scale up uplinjanje uplinjevalnik z dvojnim lebdečim slojem simulacije true false true Angleški jezik Slovenski jezik Znanstveno delo 2017-08-25 09:22:45 2017-08-25 09:23:49 2022-08-01 14:15:52 2019-07-11 16:26:25 2015 0 0 str. 394-402 št. 2 Letn. 62 2015 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1318-0207 66.07 14086149 18783254 10.17344/acsi.2014.1060 1318-0207 URN:SI:UM:DK:E1AXFZOP Acta_Chimica_Slovenica_2015_Narobe_et_al._Scale-up_research_in_a_dual_fluidized_bed_gasification_process.pdf Acta_Chimica_Slovenica_2015_Narobe_et_al._Scale-up_research_in_a_dual_fluidized_bed_gasification_process.pdf 1 AB23E546B9E8076BDB8492B2DD62CEF8 4b3ac42ca47fb4b44adb76a53315dfdd989581bccde7607cc82de653e5a85af3 8f963dd2-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/da22c487-8ece-428a-a1b4-011b98af70f0 https://dk.um.si/Dokument.php?lang=slv&id=116022 https://journals.matheo.si/index.php/ACSi/article/view/1060 1 https://dk.um.si/Dokument.php?lang=slv&id=116021 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
