A recently developed model was used to study the CO/CO2 ratio inside a burning pulverized coal particle, to better understand the effect of bulk gas composition on the equilibrium partial pressure of reduced metal species at the surface of ash inclusions. The motivation was to improve the ability to model submicrometer particle formation by ash vaporization, as a function of furnace conditions....

Abstract: In this paper, an approach is introduced to get complete rulebase fiom recorded data. At the beginning, a small number of fuzzy sets are defined on each variable to get a complete rulebase....

electric arc furnaces (eafs) are unbalanced, nonlinear and time varying loads, which can cause many problems in the power system quality. in steel industries, the two arc furnaces often perform in parallel and stand on a single bus, which surely deteriorate the power quality. in this paper, in order to study and analyze the harmful effects of parallel operation of eafs, first, a three phase arc...
