Abstract
In a method of removing heavy tar produced in a coke oven during the cooling of a coke-oven gas from the coke-oven gas, the heavy tar pieces are crushed in a pulverizer to obtain particles of the size of less than 1 mm. The heavy tar particles are then rarefied by the addition to them of a mixture of tar and water. The resulting mixture is maintained under the temperature of 55.degree.-75.degree. C. and then transported to a charge coal which is then charged into the coke-oven.
