Investigating Effects of Varous Hydrodynamic and Thermal Parameters on Sintering Process Saeed Sadeghi eng s sadeghi@yahoo com 2009 04 26 Department of Mechanical Engineering Isfahan University of Technology Isfahan 84156 83111 IranDegree M Sc Language FarsiDr M Davazdah emami mohsen@cc iut ac irDr M Panjehpour panjepour@cc iut ac irDr A Saboonchi AbstractA transient two dimensional combustion model of a solid fuel bed that can be applied to various types ofcombustors employing the solid bed is presented in this work Solid gas reactions gaseous reactions heattransfer changes in bed porosity and physical properties are modeled and envisaged in each term of thegoverning equations A two medium treatment is applied for the energy equation The solid bed materialsare homogenous whose contents include iron ore limestone coke and moisture Numerical simulationshave been done for various coke content 3 4 3 8 4 2 Effects of various air supply rates 0 26 0 32 0 42 0 46 0 52 m s have been investigated Two different fuel particle diameters have been simulated Also effects of fuel substitution have been investigated The simulation results were compared with theexperimental data Quantitative parameters are newly defined for characterization of the bed combustion These include flame front speed sintering time duration time in the combustion zone combustion zonethickness melting zone thickness and the maximum temperature Relationships between theseparameters and the mechanism of combustion propagation are also investigated The results showquantitatively that temperature profiles combustion propagation and thickness of the combustion zone inthe bed are dominated by combustion related operating parameters Key wordsIron ore sintering bed Fixed bed combustion Simulation Solid fuel
