Title:
【発明の名称】微粉炭の搬送性向上方法
Document Type and Number:
Japanese Patent JP2986717
Kind Code:
B2
Abstract:
A solid compound having a volume average particle diameter of not more than 5 mu m, for example, silicon dioxide, aluminum oxide, calcium carbonate, or silicon cabide, is adhered on a dried fine coal obtained from a raw coal having an average HGI of not less than 30 in such a manner that the value of alpha falls within the following range to improve the transportability of the fine coal: k1 . r<0.59> and r represents the volume average particle diameter ( mu m) of the solid compound added. As a result, the fine coal is improved in fluidity and thus can be used as an injection fuel for blast furnaces and a fine coal firing boilers. Further, it is possible to prevent hanging and changing within hoppers and clogging of piping.
