Temperature Field Simulation Model for Rotary Kiln of Iron Ore Oxidized Pellet Original Research Article

Based on conduction, convection and radiation heat transfer among the flue gas, kiln wall, and the pellet bed material, and on the basis of the coal combustion and analysis of reaction heat of pellet induration in the rotary kiln, the temperature field model of rotary kiln was established. Using visual studio net, matlab and open source computer vision library as development tools, combining with the ActiveX data objects database technology, the temperature field simulation system for rotary kiln of iron ore oxidized pellet production was developed. Temperature distribution of pellet and flue gas in rotary kiln was dynamically displayed.
