MIXING PROCESS FOR COMBUSTION FURNACES

摘要

A system and method for increasing combustion furnace efficiency, including the steps of providing a furnace with a plurality of secondary air injection ducts, asymmetrically positioned in an tangentially reinforcing manner; injecting fuel with substoichiometric primary air through the burners; injecting secondary air through the plurality of secondary air injection ducts; wherein the velocity of the injected air is such that the ratio of the advected air velocity to the furnace width is between about 2 sec-1 to about 150 sec-1; thereby increasing combustion efficiency and reactor efficiency via mixing and rotation of the combustion space.
