A method is described for recovering and utilizing heat of coke- oven gas is eliminated. Through heat exchange with a high-temperature coke-oven gas generated from a coke oven battery and containing vaporized coal tar, vaporized low boiling point substances and dust. By drying and preheating a blended raw material coal fine to be charged into coking ovens of said coke oven battery, and causing most of said coal tar contained in said coke-oven gas to condense and deposit onto the particle surfaces of said coal fine. During the process of said heat exchange, sensible heat and condensation heat of said coke-oven gas and substances contained therein are recovered and utilized, and at the same time, most of the contained coal tar from said coke-oven gas.
