Equivalent straight pipe heat transfer model of cement clinker porous media in grate cooler
摘要
Abstract
For the study on porous cement clinker, researchers solve the equations of Darcy’s law and local no-thermal equilibrium heat transfer based on the theory of heat transfer of fluid flow in porous media. However, the solving process is complex and not convenient for engineering application. A kind of straight pipe equivalent heat transfer model was established by introducing the theory of straight pipe heat exchange to unit body of porous cement clinker. In order to decrease the difficulty of the solving process, the methods and ideas based on the theory of straight pipe heat transfer were used to solve the heat transfer process of porous cement clinker. On the premise of ensuring calculation precision, the changes of temperatures of both clinker and gas with time were obtained. A self-designed experimental equipment was used to verify the temperature expressions at different porosities. The calculation results basically agreed with the experimental data, which verified the feasibility of straight pipe equivalent heat transfer model.关键词
