The burning characteristics of pulverized coal in blowpipe and tuyere at two different injection patterns are simulated numerically, to aid improving the practical performance of blast furnace. With the condition of the same fuel and oxidant mass flow rates, the predictions indicate that the combust
technology non-optimum regime for the Romelt process, the regime in which coal blocks the surface of the slag bath. The results of the studies were used to develop a technology for a Romelt unit with a capacity of 320000 tons of pig iron a year.
0 1 Solid fuels (transport, storage) binary organic solvent mixtures commonly used in such experiments. By matching coal and solvent solubility parameters swelling is maximized. The experiment takes note, however, of supplementary effects, including those accompanying the entry of solvent into the c
