<p><P>PROBLEM TO BE SOLVED: To provide a system for waste disposal capable of reducing loads on the environment by suppressing the generation of nitrous oxide. <P>SOLUTION: The system includes: a pyrolysis furnace 3 for accepting organic waste to pyrolyze the organic waste under a reducing atmosphere at high temperature; a combustion furnace 4 for combusting the combustible pyrolysis gas generated in the pyrolysis furnace; one or more heat utilization equipment 2, 3, 5 for utilizing as a heat source the combustion exhaust gas generated in the combustion furnace; and reflux lines L7, L71, L72, L73 for refluxing a low temperature exhaust gas which resulted in low temperature since used in the heat utilization equipment, to any equipment disposed at the upper stream than the heat utilization equipment so as to be used in the upper stream equipment as a combustion air or dilution air therein. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
