HEAT AND MASS TRANSFER IN AROTARY KILN

2018-7-14  mathematical model of rotary kiln incinerator was developed. The model performs both heat and mass balances and heat transfer analyses in a rotary kiln combustor. The heat transfer mechanism includes radiative, convective and conductive heat transfer among combustion gases, the kiln wall and the solid bed. The model was used to predict the fuel requirement, flue gas properties, and axial temperature profiles of the solid bed, the kiln inner wall and outer skin. The model can be a useful tool in the design and operation of rotary kiln
