Abstract

PURPOSE: To prevent the loss of fine coal particles due to scattering, etc. and to enhance the yield of coal, by a method wherein fine coal particles are slurried in heavy oil, the slurry is atomized into a gasification fluidized bed of coal to granulate the fine particles to a required size, to gasify coal.
CONSTITUTION: Coal (or char) 17 having a particle diameter of 1mm or larger and a particle diameter distribution of a particle diameter ratio of the lower limit value to the upper limit value of 2W3, is supplied from a hopper 16 to a gasification furnace 6 which is heated. At the same time, oxygen 8 and steam 9 are supplied to the furnace to burn coal. When the height of fluidized bed reaches the required level, the supply of coal is stopped. Slurry 4 is prepared from fine coal particles 1 having a particle diameter of 1mm or smaller and at least 70wt% (based on the weight of said fine coal particle) having oil 2 in a tank 3. Said slurry 4 and steam 7 are blown into the fluidized bed to gasify coal. The generated gas 18 is passed through a cyclone 11, a scrubber 12 and a cooler 13 to remove fine powder 14, liquid products (tar and waste water) 15, etc., and then is recovered. Ash 10 is withdrawn from the lower part of the gasification furnace 6.
