摘要： PURPOSE: Coal briquette using pulverized coal and a manufacturing method of the same are provided to improve productivity by using a water soluble caking material. CONSTITUTION: Coal briquette includes 3 to 10 parts by weight of a caking material based on 100 parts by weight of a coal mixture. The coal mixture includes raw material coal of 3mm average diameter and pulverized coal of 0.3mm or less diameters at the weight ratio of 1:1. The caking material includes 50 to 90 weight% of a poly(vinyl alcohol) aqueous solution of 3 to 10 wt% concentration and 10 to 50 weight% of polyalcohol. The pulverized coal is generated from a coal moisture control process which transfers raw material coal from a production region to a consumption region. The polyalcohol is one or more selected from glycerin, ethylene glycol, and propylene glycol.
摘要翻译：目的：提供使用粉煤的煤块及其制造方法，以通过使用水溶性结块材料提高生产率。构成：基于100重量份的煤混合物，煤团块包含3至10重量份的结块材料。煤混合物包括3mm平均直径的原料煤和0.3mm或更小直径的粉煤，重量比为1：1。结块材料包括浓度为3〜10重量％的聚（乙烯醇）水溶液的50〜90重量％，多元醇为10〜50重量％。煤粉是从生产区域将原料煤转移到消费区域的煤水分控制过程产生的。多元醇是选自甘油，乙二醇和丙二醇中的一种或多种。
