摘 要:<正> In this paper for saving energy two differentburning methods of cement clinker formation havebeen studied.One is the rapid burning method andthe other is ordinary burning method simulatingrotary kiln,and they are compared by the kineticpoint of view.The result reveals that theactivation energy of rapid burning is much lowerthan ordinary burning.For looking into the cause,the main raw material—lime stone was burnt bythe same two methods and the structure of productCaO has been detected.It can be found that themicrostructure of CaO produced by rapidburning is looser;lattices constants aregreater;crystal defects are more and particlesize is smaller than that produced by ordinaryburning.These cause the chemical reaction moreactive.So the activation energy of clinkerformation of rapid burning is much lower thanthat of the ordinary burning.
