NOVELTY - A derived screen residue of waste is used to substitute for cement kiln fuel by sieving household waste, and packing derived screen residue of waste having heat component to be waste package after removing iron and primary smashing; transferring waste package to package-breaking machine to break the package; transferring the derived screen residue of waste after breaking the package to a crusher to crush, stirring, and mixing; and introducing the screen residue of the waste into cement kiln to substitute for the fuel to burn.    USE - Method for using derived screen residue of waste to substitute for cement kiln fuel.    ADVANTAGE - The method is capable of saving coal resources. The cement kiln has high temperature, big capacity, does not produce draff during processing the waste, and does not cause secondary pollution, thus providing energy-saving and environment protection.    DETAILED DESCRIPTION - Utilizing derived screen residue of waste to substitute for cement kiln fuel involves:    (A) sieving household waste, and packing derived screen residue of waste having heat component to be waste package after removing iron and primary smashing;    (B) transferring waste package to package-breaking machine to break the package;    (C) transferring the derived screen residue of waste after breaking the package to a crusher to crush, stirring, and mixing; and    (D) introducing the screen residue of the waste into cement kiln to substitute for the fuel to burn, in which part of the mixed screen residue of the waste is transmitted to pre-ignition kiln to burn after removing iron.    A temperature of the pre-ignition kiln is 700-900 degrees C. An entrance of the pre-ignition kiln is at negative pressure. The other part of the mixed screen residue of the waste enters into the cement kiln to burn from the kiln head.
