METHOD FOR RE-TREATING BOTTOM ASH IN COAL-FIRED POWER STATION

摘要

PURPOSE: A method for reusing bottom ash in thermoelectric power is provided to recycle 100% of bottom ash simply and economically. CONSTITUTION: A method for reusing bottom ash of thermoelectric powder comprises: a step of collecting bottom ash into a supply hopper(5) using conveyor be a step of pulverizing the bottom ash in 200 to 500 mesh of size; a step of heating in a preheating tank(20) at 400~700C to remove moisture; a step of heating the fine power of the bottom ash using indirect heat in a burning tank(30); a step of reading image in a burning state image reader(36) to determine whether the burn is performed normally; a step of controlling transfer to cooling tank(40) or preheating tank; and a step of cooling pure ash.
