    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.

    Abstract translation: 在从焦炉气体冷却焦炉煤气的同时,在焦炉中除去重焦油的方法中,将重焦油片在粉碎机中粉碎,得到尺寸小于1mm的颗粒。 然后,通过加入焦油和水的混合物,重质焦油颗粒被稀释。 将所得混合物保持在55-75℃的温度下,然后运送至装料煤,然后将其装入焦炉中。
