Title:

PULVERIZED COAL CARRIABILITY IMPROVER

Document Type and Number:

WIPO Patent Application WO/1997/036009

Kind Code:

A1

Abstract:

A pulverized coal carriability improver which can improve the carriability of a pulverized coal and enables the pulverized coal to be used as a blown fuel for a metallurgical furnace or a combustion furnace. The improver can further provide a pulverized coal which can prevent hanging and channeling in a hopper and pipe clogging. Water-soluble inorganic salts having a polar group, such as BaCl2, CaCl2, Ca(NO2)2, Ca(NO3)2, Ca(Cl0)2, K2CO3, KCl, MgCl2, MgSO4, NH4BF4, NH4Cl, (NH4)2SO4, Na2CO3, NaCl, NaClO3, NaNO2, NaNO3, NaOH, Na2S2O3, NaS2O5, HNO3, H2SO4, H2CO3, or HC1, are affixed to a dried pulverized coal having an HGI of at least 30 in terms of the average HGI of a feed coal at an injection port of a metallurgical furnace or a combustion furnace.
