    Coal based Direct Reduction Rotary Kiln Process – IspatGuru

    Feb 14, 2017 Coal with very low volatile matter result in very low reactivity of char, and thus give rise to poor metallized product. Very high volatile coals, though yield highly reactive char, are also not preferred since it increases gas volume in the kiln. Normally for rotary kiln process volatile matter is to be in the range of 25 % to 30 %. Coals for direct reduction in the rotary kiln need

    Dec 01, 2012 The pneumatic coal injection and combustion process in a commercial rotary kiln is modeled in this work using a two phase flow theory approach. The physical and chemical phenomena of the turbulent reacting flow is simulated using a multiphase Eulerian–Lagrangian CFD approach where the gas phase is treated as a continuous phase and the pulverized coal

    Sep 11, 1992 The purpose of this project was to demonstrate the combustion of coal and coal wastes in a rotary kiln reactor with limestone addition for sulfur control. The rationale for the project was the perception that rotary systems could bring several advantages to combustion of these fuels, and may thus offer an alternative to fluid-bed boilers
