The study of the burner angle optimization that effect on the temperature distribution lime kiln by finite volume method

Abstract

This research is the three dimensional modeling of a lime kiln, which is used in Phoenix Pulp & Paper Public Co. Ltd. for reforming calcium carbonate to calcium oxide (or lime) in order to reuse in the process. The kiln is the horizontal cylinder driven by motor to rotate around axis. This research studied the characteristics of the angle of the burners placed in different ways. In the analysis, the nite volume technique, in Computational Fluid Dynamics (CFD) program, was used to evaluate the angle of burner that gives the best temperature distribution. The CFD model is compared with the measured temperature to verify boundary condition and mesh quality. The burner’s angle is then adjusted in different position in CFD model. The optimum angle can be obtained by observing the temperature at the entrance of kiln , the maximum temperature at the entrance represents the best temperature distribution. The obtained optimum angle is in the coordinate (0,-2). This position provides the best temperature distribution. It leads to better temperature distribution in Lime kiln and further development
