<p><P>PROBLEM TO BE SOLVED: To provide a disposal method and device for combustible waste capable of continuously carrying out safe operation without any trouble in operation, and preventing accumulation of combustion residues in the bottom of a combustion space, when carrying out combustion disposal of combustible waste such as waste plastic in a cement manufacturing device. <P>SOLUTION: A midway part of a calcination furnace secondary air duct is modified into a vortex shaped high temperature space, a swirl air flow is generated in a calcination furnace, and combustible waste is inputted from an upper part to carry out combustion. It is a structure capable of preventing adhesion of unburned materials to an inner wall of a vortex chamber, and the bottom is adjacent to the calcination furnace so as to prevent accumulation of combustion residues of the combustible waste in the bottom of the vortex chamber. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
