Modeling of Heat Transfer in Rotary Furnaces Using Finite Element Approach

The pattern of heat flow in a 100-kg capacity rotary furnace was studied at transient state using finite element technique. The study combined volumetric analysis of combusting fuel with finite element analytical computation of heat transfer within the furnace hearth. A parabolic partial differential equation was used in combination with the results of volumetric analysis of combusting fuel, which is applicable to transient heat transfer. The results provide a finite element approach to computational modeling of medium-sized diesel-fired melting furnaces in the metallurgical industry.
