dc.description.abstractCilj eksperimentalnih istraživanja prikazanih u ovom radu jeste da se proceni stepen efikasnosti rada elektrostatičkog filtra na realnom industrijskom postrojenju (termoelektrana 'Gacko' električne snage od 310 MW, Bosna i Hercegovina) i dobijeni rezultati iskoriste za projektovanje periodičnog ili neprekidnog merenja i uporede sa rezultatima istraživanja drugih istraživača. Istraživanje performansi elektrostatičkog filtra je izvršeno u skladu sa BAS ISO 9096:2003. Efikasnost elektrostatičkog filtra je procenjena tokom uklanjanja čestica pepela u širokom opsegu veličina čestica od 1 do 250 μm. Eksploataciona iskustva ukazuju da su elektrostatički filtri efikasni za ugljeve različitog kvaliteta (prečnik čestica pepela veći od 1 ìm) i da se mogu optimizovati, kako u toku samog rada, tako i za neke naredne procese, kao što je odsumporavanje dimnih gasova. U mernim ravnima, merenja su vršena na 20 tačaka po preseku. Primećeno je da stepen uklanjanja pepela dobijen eksperimentalno (3 ispitivanja) ima približno jednake vrednosti (95,93-97,78%). Najbolje slaganje sa rezultatima eksperimentalnih ispitivanja pokazuje jednačina Deutsch-a, dok teorijski modeli Zhibin-Guoquan i Nobrega-Falaguasta-Coury ne aproksimiraju najbolje rezultate eksperimentalnih ispitivanja. Za čestice pepela prečnika manjeg od 17,5 μm ne postoji dobra korelacija između ispitivanih teorijskih modela. Najveće odstupanje modela za čestice pepela prečnika manjih od 17,5 μm je primećeno u slučaju upotrebe jednačine Deutsch-a.sr
dc.description.abstractThe goal of experimental investigations shown in this paper is to estimate the operating efficiency degree of the electrostatic precipitator on a real industrial plant (a the thermal power plant 'Gacko' with the electric power of 310 MW, Bosnia & Herzegovina) and to use the obtained results as a base of periodical engineering or continual measurement and compare them with the investigations of other investigators. The investigation of the electrostatic precipitator performance was done according to BAS ISO 9096:2003. In this paper, the electrostatic precipitator efficiency during the ash particle removal with a wide range of particle sizes from 1 to 250 μm is evaluated. The exploitational experience points out that electrostatic precipitators are efficient for the coals of different quality (coal particles with diameters bigger than 1 μm) and that they could be optimized during the exploitation itself and for some following processes (e.g., flue gas desulphurization). Within the measurement plane, the measurements were made on 20 points per section. It has been noticed that ash removal degrees obtained experimentally (3 investigations) have approximately equal value (95.93 to 97.78%). The best concordance with the results of experimental investigation shows the Deutsch equation, while theoretical models of Zhibin-Guoquan and Nobrega-Falaguasta-Coury do not correspond well to the results of experimental investigations. For the ash particles with the diameters less than 17.5 μm there is no good correlation between investigated theoretical models. The highest deviation of the model for ash particles with diameters less than 17.5 μm is notable in the case of using the Deutsch equation.en
