In the experiment, a fluidized bed was heated using Ar plasma and electricity. The temperature was tested at different levels of the reactor in the preheating, reacting period and finishing reacting with the content electricity heating rate. The results showed that the duration of time required to preheat the reactor to the experimental temperature by using electricity was longer than that required by using Ar plasma, which was usually 60min. When electricity was used, the peak difference in temperature between the beds was measured at about 200℃, while the difference attributed to Ar plasma heating was about 50℃. Further, Ar plasma heating resulted in even distribution of heat and steady operation of the fluidized bed. 
