This paper deals with the injection of alternative fuels into a blast furnace and their effect on the blast furnace's operation. In this case oil injection was replaced by coal-tar injection. A comparison analysis of the brown-coal generator tar injection and oil injection was applied to assess the effect of the injection on the reduction of COsub2 emissions. The daily parameters of the inputs and outputs were available. The statistical relations for the injection of brown-coal tar and the significant parameters of the aggregate are studied. Correlation coefficients indicating the tightness in the tar injection and other significant technological parameters, such as the specific coke consumption, theoretical combustion temperature and the emissions of the blast furnace are calculatedEkstremno visoke zahteve po energiji pri proizvodnji železa v plavžu in velika polucija z ogljikovim dioksidom zahtevajo sistematično prizadevanje za zmanjšanje specifične porabe goriv in dezoksidacijskih sredstev pri tem postopku. Ta članek obravnava vbrizgavanje alternativnih goriv v plavž in njihov učinek na delovanje plavža. Vbrizgavanje olja je bilo nadomeščeno z vbrizgavanjem katrana iz premoga. Izvršena je bila primerjalna študija vbrizgavanja generatorskega katrana iz rjavega premoga ter vbrizgavanja olja za oceno učinka vbrizgavanja na zmanjšanje emisije COspodaj2. Na voljo so dnevni parametri vhodnih in izhodnih snovi. Študirano je bilo statistično razmerje med vbrizgavanjem katrana iz rjavega premoga in pomembnimi procesnimi parametri plavža. Izračunani korelacijski koeficienti kažejo tesno povezavo med vbrizgavanjem katrana in drugimi pomembnimi tehnološkimi parametri, kot so poraba koksa, teoretična temperatura zgorevanja in emisije iz plavžaTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
