Burner swirl intensity control apparatus and method for controlling the intensity

摘要

An oxidant supply pipe for supplying a secondary oxidant in the form of a double pipe to the outside of the fuel supply nozzle to which the fuel of the burner is supplied for securing the stability of the flame and a vane for supplying the secondary oxidant in a swirl flow between the fuel supply nozzle and the oxidant supply pipe Wherein the regulating device is provided between a plurality of vanes fixed at a predetermined angle to one surface of the oxidant supply pipe in accordance with a flow rate of fuel supplied through the fuel supply nozzle And a regulating member for regulating a path width of the secondary oxidant, and a method for regulating the intensity of the burner swirl flow.Accordingly, the swirling flow strength of the secondary oxidant can be controlled according to the flow rate or type of the supplied fuel, thereby ensuring the stability of the flame and safely using it, as well as maximizing the combustion efficiency.
