Heat transformer with gassolid reaction could be used to upgrade waste heatIn this paper,the transient temperature profiles within the reactor for heat transformer were studied and some basic characteristics of temperature distribution were analyzed with the variation of parameters,such as TC,pC,fg and ρbThrough analyzing the temperature distribution profile,it was concluded that with the increase of pC and ρb,and decrease of TC and fg,the temperature rise within the reactor and the heating power for waste heat fluid increased,while the temperature distribution became more nonuniform.
