Abstract

PURPOSE: To prepare the titled fuel without precipitation of fine powder coal during transportation and storage, by adding fine powder coal to a liquid having specific gravity almost equal to that of the fine powder coal.
CONSTITUTION: Fine powder coal with a particle size of 5W10μ is supplied in the first mixing machine 4 through a hopper 1, a feeder 2 and a scale 3 to be mixed with a desulfurizing agent supplied through a hopper 1B, a feeder 2B and a scale 3B, a fine powder for adjusting specific gravity supplied through a hopper 1C, a feeder 2C and a scale 3C and a liquid such as water, an oil or the like supplied from a pipe passage 5 therein. Then, the specific gravity of the obtained mixture is sent from a liquid specific gravity transmitter 16 to be compared with the specific gravity applied to and memorized in a control box 15 and a command signal thereof is outputted to a flow amount control valve 17, the feeders and the scales to prepare a liquid having specific gravity almost equal to that of the fine powder coal. Subsequently, said liquid is supplied to the second mixing machine 8 through a pipe passage 7 to be mixed with the fine powder coal with a particle size of 70W100μ sent through a hopper 1A, a feeder 2A and a scale 3A and, thereafter, the resulting coal slurry fuel is sent to a storage tank 10 through a pipe passage 9.
