Method and Apparatus to Clean Ash from Ash Ponds or a Landfill

摘要

A method of cleaning an ash material byproduct of a coal fired power plant of metal and hydrocarbon impurities. Dewatered feed material containing the ash material byproduct is preheated and crushed and then heated in a volatilizer to a temperature at which the metal and hydrocarbon impurities are volatilized. The ash is then separated from the volatilized materials.
