Title:
APPARATUS FOR CONTROLLING COMBUSTION OF FURNACE WITH OXYGEN LANCING
Document Type and Number:
WIPO Patent Application WO/2015/060590
Kind Code:
A1
Abstract:
The present invention relates to an apparatus for controlling combustion of a furnace with oxygen lancing that additionally supplies oxygen together with air as an oxidizing agent of injected fuel, so that the quantity of NOx generated can be reduced, unlike the conventional practice wherein NOx is discharged in large quantities due to the increment of N2 in the air used as a single oxidizing agent. According to the present invention, the apparatus comprises: a heating furnace which has a combustion chamber formed at the inside thereof so as to accommodate a material to be heated therein; a burner disposed in the heating furnace which receives fuel and air to conduct the combustion of the combustion chamber of the heating furnace; a fuel supply line which supplies the fuel to the burner; an air supply line which supplies the air to the burner; an oxygen supply line which directly supplies oxygen to the interior of the combustion chamber of the heating furnace; and a combustion controller connected to the fuel supply line, the air supply line and the oxygen supply line, respectively, which receives the atmosphere temperature inside the combustion chamber and controls the flow rate of the fuel and the flow rates of the air and oxygen, as oxidizing agents supplied to the burner and the combustion chamber of the heating furnace, respectively, to reach a target temperature to be converted.
