PURPOSE: A bottom ash re-processing apparatus for a coal-fired power plant is provided to prevent the environmental contamination caused by bottom ash by simply re-processing the bottom ash into pure ash. CONSTITUTION: A bottom ash re-processing apparatus for a coal-fired power plant comprises the following: a conveyor belt receiving bottom ash(100) discharged from a furnace of the coal-fired power plant and transferring to a micro-grinder; the micro-grinder crushing the bottom ash into micro-powder; a combusting cylinder re-combusting the micro-power; and a cooling pipe cooling the combusted bottom ash, and discharging as pure ash. The combusting cylinder includes an outer cylinder(11), a fire-proof layer(12) fixed to the inner wall of the outer cylinder, a heating combustion layer(17), an inner side cylinder(14) forming an air electro-thermal layer(13), and a transfer screw(16). |
