ABSTRACT:
A method and furnace assembly for treating solid refuse. The refuse comprises both recoverable materials useful either in cement or in construction and contaminants. The contaminants have a vaporization temperature lower than the vaporization or sublimation temperatures of the recoverable materials. The furnace assembly comprises a resource recovery furnace connected to a cement manufacturing furnace. According to the method, the refuse is transferred through a resource recovery furnace. Inside the resource recovery furnace the refuse is separated into vaporized contaminants and recoverable materials. Gas carrying the vaporized contaminants is transferred to the cement manufacturing furnace and used as an energy source. The recoverable materials are used in the cement manufacturing furnace as a constituent for making cement.
