The results of the transportation loop tests indicate that the pressure drop of coal oil mixture (COM) in the pipe can be precisely estimated under the condition that the rheological characteristics of COM are determined by a pseudo-plastic fluid model and the apparent viscosity is measured by the cone and plate viscometer. Through the COM combustion test by LBF it was found that 70 to 85% intected fine coal was combustible in the raceway and there was little difference in the gas permeability between COM and oil injection. The replacement ratio of COM to heavy fuel oil was estimated to be about 0.8 to 0.9 by the mathematical blast furnace simulation model. The injection test into three tuyeres of a large commercial blast furnace has been performed with remarkable success since September 1980. The useful results obtained from these test will be reflected to the commercializing injection test into all tuyeres of Kashima No. 1 blast furnace. 36 figures, 1 table.
