PROCESS OF HIGH-TEMPERATURE SPIRAL FLOW COMBUSTION AND WASTE TREATMENT EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a process of high-temperature spiral flow combustion and waste treatment equipment reduced in the time lag of controlling the quantity of air in a second stage combustion chamber regardless of a time lag in measuring the oxygen content of exhaust gas. SOLUTION: The process of subjecting an incineration object generated by pyrolizing wastes to two-stage combustion while it flows in A spiral at a high temperature comprises the steps of introducing the quantity of air less than the stoichiometric mixture ratio of the incineration object into a first combustion chamber, adjusting the quantity of air introduced into a second combustion chamber such that the oxygen concentration of exhaust gas discharged from the second combustion chamber falls within a set range, measuring the temperature of the first stage combustion chamber and compensating the quantity of air introduced into the second stage combustion chamber based on the measured value so as to reduce the delay of controlling the quantity of air in the second stage combustion chamber.
