REBURN PROCESS

摘要

A process and apparatus for combustion in which a combustible material is introduced into a combustion chamber and oxidant is supplied to the combustion chamber combusting the combustible material, and forming a primary combustion zone. A mixture of flue gases and flyash having an organic content is injected into the combustion chamber downstream of the primary combustion zone to create an oxygen deficient reburn zone, thereby lowering the temperature of combustion, reducing the NOx content of the flue gases, and reducing the potential for NOx formation in a tertiary oxidizing combustion zone disposed downstream of the oxygen deficient reburn zone.
