Abstract：In the process of boiling chlorination production，the particle size，the ratio of carbon to carbon，the reaction temperature and the airflow velocity are the main factors affecting the chlorination effect. The particle size and its distribution are the most important influencing factors. The minimum particle size of the raw material should be greater than the maximum particle size of the furnace in the process of chlorination，the maximum particle size of the material in the process of floating the body，the maximum particle size should be less than the existing carrier gas pressure can float the largest particle size. From the two aspects of chemical kinetics and hydrodynamics，the velocity of air flow and the particle size matching were calculated，the particle size distribution of the raw material was matched by calculating the airflow velocity and the particle size matching of the raw materials，and the particle size range was corrected by the data analysis in the production practice range. The distribution range of the raw material particle size was matched with the structure of the boiling chiorination equipment.
