Author has discussed the feasibility to convey the pulverized coal by CO2 gas as pneumatically conveying medium in replace of N2 gas; using the Aspen Plus simulation program, the coal drying model was established, through the simulation calculation, relative process parameters of coal drying system have been obtained and the sensibility analysis was made tbr the relatively key parameters. Result indicates that the CO2 gas as the medium of pulverized coal pneumatic conveying can satisfy the process requirement, and the simulation analysis can reasonably predicted the important factors of influencing the key constituent concentration.
