Sažetak
Nivo svesti o zaštiti životne sredine u svetu je porastao poslednjih godina, a ekonomisti predviđaju njegov dalji, eksplozivan rast. Ovakva predviđanja ističu u prvi plan značaj smanjenja uticaja zagađivača vazduha, vode i zemlje. Oblast koja je od posebnog značaja je briga o mogućnosti formiranja kiselih kiša usled izdvajanja SO2 i azotnih oksida tokom sagorevanja fosilnih goriva. U tom smislu se ističu i programi odsumporavanja dimnih gasova koji se sprovode dugi niz godina u elektranama širom sveta, a poslednjih godina i u nas. U ovom radu su opisani suvi postupci odsumporavanja dimnih gasova kotlova na sprašeni ugalj - direktnim unošenjem sorbenta u ložište, unošenjem sorbenta u kanal iza zagrejača vazduha ili u za to posebno projektovan reaktor kao i suvi sistem sa raspršivanjem. Posebno se razmatra ekonomski aspekt i efikasnost redukcije emisije SO2. Izbor metode je šesto zasnovan na poređenju cene primene metoda. Stoga su za opisane tehnologije dati prosešni troškovi redukcije emisije i istaknute one najefikasnije. PR Projekat Ministarstva nauke Republike Srbije, br.
