回转窑物料层挥发分及温度分布特性分析
Analysis of volatile matter and temperature distribution characteristics in rotary kiln material layer
摘要
Abstract
The rotary kiln is the core equipment in the production of asphalt coke.Its combustion process integrates multiple physical fields such as flow,heat transfer,mass transfer and the rotational motion of materials,as well as chemical reactions,and is a typical complex coupled process.Considering the influence of physical and chemical reactions on the heat transfer process inside the kiln,for a rotary kiln with a length of 55 m,a one-dimensional axial comprehensive heat transfer mathematical model is established to analyze the heat transfer law under the reverse flow of gas and materials inside the kiln.A material volatilization analysis model and a material layer heat transfer model are constructed,and the volatilization rate curve and the temperature distribution curve of the material layer are obtained through calculation.The results show that the volatilization rate is the highest at approximately 15 m from the kiln tail,and the temperature of the material layer reaches the highest at approximately 38 m.关键词
