Abstract

A process for deashing coal, which comprises carrying finely pulverized coal using a non-oxidative gas stream (A), adjusting the temperature and humidity of the pulverized coal-carrying non-oxidative gas during carrying, introducing the gas into a dry electric dust-collecting room (2) to capture and separate ash particles based on the difference in intrinsic resistance between carbon particles and ash particles, and recovering highly pure, finely pulverized coal (B) carried on the non-oxidative gas at an outlet (3) of the dry electric dust-collecting room.
