STRUCTURE TO COMPLETELY BURN AGAIN THROUGH UTILIZATION OF THERMAL CONDUCTION SURFACE IN GENERATION OF HEAT DURING INCINERATION, STRUCTURE OF ASH REMOVAL PORT, AND METHOD FOR SUPPLYING AIR

摘要

PROBLEM TO BE SOLVED: To perform agitation combustion in first and second stage combustion chambers by the nozzle angle of an artificial ventilating device and further perform complete combustion in the first stage combustion chamber by a thermal conduction wall surface having a high heat generated by the agitation combustion, in a theme of a problem point where, in a conventional general incinerator, with a main combustion zone being not completely burnt, gasification is carried out and guidance to a chimney is effectively discharged in air and decision of the problem is demanded. ;SOLUTION: A main combustion zone is oxidized through a swirl agitation combustion by mounting an air supply nozzle 12 in a clockwise down direction in a first stage combustion chamber. Agitation combustion is practicable with a brake being applied by an upper supply nozzle 13 in a central down direction in a second stage combustion chamber. Further, through the passage of it through a smoke tube, filtration and thermal combustion of flying ash are effected. In a third stage combustion chamber, through contact of it with a high thermal conduction wall surface, dioxin is completely burnt and discharged.;COPYRIGHT: (C)2000,JPO
