METHOD FOR REDUCING TOXIC SUBSTANCE IN EXHAUST GAS AND INCINERATOR

PROBLEM TO BE SOLVED: To provide a method for reducing a toxic substance in exhaust gas to enable suppression of the toxic substance, such as an organic chlorine compound and halogen compound, containing unburnt gas, such as carbon monoxide and aromatic hydrogen carbide in exhaust gas, and dioxin to low concentration. SOLUTION: Based on gas concentration in a combustion chamber and/or a component of incinerated ash, the movement speed of a part or a whole of a substance to be incinerated is controlled. Further, it is preferable that based on gas concentration in a combustion chamber and/or a component of incinerated ash, a flow rate of an oxidizing agent is controlled or based on gas concentration in the combustion chamber and/or a component of incinerated ash, a movement velocity of a part of a whole of a substance to be incinerated and a flow rate of an oxidizing agent are controlled.
