    摘要： The use of pulverized coal as the fuel to be injected into a metallurgical or combustion furnace becomes possible enabled by improving the transportability thereof. Further, a pulverized coal is provided, which is inhibited from bridging or channelling in a hopper, or piping choking.
    A water-soluble inorganic salt having a polar group is made to adhere to pulverized coal which is prepared from raw coal having an average HGI of 30 or above and which is in a dry state at the injection port of a metallurgical or combustion furnace, the inorganic salt being selected from among BaCl 2 , CaCl 2 , Ca(NO 2 ) 2 , Ca(NO 3 ) 2 , Ca(ClO) 2 , K 2 CO 3 , KCl, MgCl 2 , MgSO 4 , NH 4 BF 4 , NH 4 Cl, (NH 4 ) 2 SO 4 , Na 2 CO 3 , NaCl, NaClO 3 , NaNO 2 , NaNO 3 , NaOH, Na 2 S 2 O 3 , NaS 2 O 5 , HNO 3 , H 2 SO 4 , H 2 CO 3 , and HCl.

    摘要翻译： 通过提高其输送性，可以实现将粉煤作为喷射到冶金炉或燃烧炉中的燃料的使用。 此外，提供了一种粉碎煤，其被阻止在料斗中桥接或引导，或管道阻塞。 将具有极性基团的水溶性无机盐与由平均HGI为30以上且在冶金或燃烧炉的注入口处于干燥状态的原煤制成的粉煤附着， 无机盐选自BaCl 2，CaCl 2，Ca（NO 2）2，Ca（NO 3）2，Ca（ClO）2，K 2 CO 3，KCl，MgCl 2，MgSO 4，NH 4 BF 4，NH 4 Cl，（NH 4）2 SO 4，Na 2 CO 3，NaCl， ，NaNO 2，NaNO 3，NaOH，Na 2 S 2 O 3，Na 2 O 5，HNO 3，H 2 SO 4，H 2 CO 3和HCl。
