description Rotary kilns are tools which wide range used and mostly are used in cement production process. Key parameter of rotary kiln is temperature profile inside rotary kiln. The products quality and efficiency of rotary kilns can be improved if the temperature could be set precisely and heat distribution inside rotary kiln is known. One of the ways can be done to find out temperature profile in rotary kiln by using Computational Fluid Dynamics (CFD) simulation. Several operating parameters that affect the work of a rotary kiln including primary air, secondary air, burner distance, etc. In this research, a CFD simulation was performed on rotary kiln to see a heat flow and the influence of primary air and swirl burner distance on temperature profile in rotary kiln.
