Title:
METHOD FOR TREATING COMBUSTION GAS
Document Type and Number:
Japanese Patent JP2000297914
Kind Code:
A
Abstract:

To provide a method for treating combustion gas to remove hazardous substance, such as NOx and a nitrogen compound, from combustion gas generated during combustion of waste.

In a second reduction combustion chamber, combustion air is fed as an oxygen feed amount lower than a stoichiometric quantity necessary to oxidize a total amount of a combustible component remaining in combustion gas is maintained. By feeding gas, containing oxygen having concentration lower than air, to the second reduction chamber, the gas is burnt in reductive combustion atmosphere and a nitrogen compound is decomposed into N2 as reconversion of a nitrogen compound to NOx is prevented from occurring.
