Single ball-element combustion process for HTGR fuel reprocessing

Technical Report:

Abstract

The specific combustion rate of a single graphite ball has ben measured in experiments and calculated by theory for removing matrix graphite in HTGR fuel reprocessing. When the temperature, partial pressure of oxygen and flowrate of gas are in steady, the specific combustion rate is approximately constant and the diameter of graphite ball shrinks linearly. In the range of 750{approx}900 deg C, the combustion will be controlled by oxidation kinetics and diffusion of oxygen in the boundary layer around ball, and the specific combustion rate can be calculated by diffusional mass transfer coefficient k{sub d} and oxidation rate constant k.
