Abstract：As a key equipment of the fourth vitrification technology,the mainly functions of the rotary calcination furnace are to convert high-level radioactive waste into oxides through calcination.The calcination temperature is the main control parameter during the calcination process,which directly affects the quality of calcined product and performance of the rotary calcination furnace.This paper established a numerical simulation model for the flow and heat transfer of high-level radioactive waste in a rotary calcination furnace,simulating the entire process of high-level radioactive waste flow,evaporation,and evolution.The influences of rotary calcination furnace speed and slope on evaporation rate and spatial temperature distribution were also analyzed through simulation.Which provides an important basis for the structural design,temperature parameter setting,and speed setting of the rotary calciner.
