    • PROBLEM TO BE SOLVED: To provide a method for producing lump coal, with which lump coal with prescribed density and strength is stably produced.SOLUTION: The method for producing lump coal includes: a kneading step to knead fine powder coal and a binder and to generate a kneaded product; and a lumping step to lump the kneaded product, wherein in the kneading step the fine powder coal heated to 100 to 200°C is supplied to the inside of a kneading vessel 5, and moisture is supplied to the inside of the kneading vessel 5. It is preferable that the moisture is water vapor and temperature of the water vapor is not higher than +20°C, or not lower than -20°C compared with the temperature of the fine powder coal in the kneading vessel. It is preferable that the moisture is water vapor and a feed rate of the water vapor with respect to the fine powder coal is 0.3-20.0 kg/ton.
    • 要解决的问题:提供一种生产块煤的方法,其中稳定地产生具有规定的密度和强度的块煤。 解决方案:块煤的制造方法包括:捏合细粉煤和粘合剂并生成捏合产物的捏合步骤; 以及将捏合物块块化的块状工序,在捏合工序中,将加热到100〜200℃的细粉煤供给到捏合容器5的内部,向捏合容器5的内部供给水分。 优选的是,与捏合容器中的细粉煤的温度相比,水蒸气和水蒸气的温度不高于+ 20℃或不低于-20℃。 优选的是,水分是水蒸汽,水蒸气相对于细粉煤的进料速度为0.3〜20kg / ton。 版权所有(C)2013,JPO&INPIT

    • PURPOSE: To obtain continuously high-quality, stable, ash-free granulated coal, by adding a binder to powdered coal water slurry, rotating impellers while controlling speed of rotation, and giving an alarm when the total number of revolution becomes ≥ a given value.
      CONSTITUTION: In a desulfurizing granulator wherein the powder coal water slurry 1 is blended with the binder 2, the impellers 10 and 11 are rotated, power for rotating the impellers is measured, and speed of rotation is controlled in such a way that the power becomes standard power. The number of rotations is measured and an alarm is given when the total number of the rotations reaches ≥ a given value.
      EFFECT: Time of exchange of impellers can be automatically expected without checking wear of impellers in detail.
