A plurality of vortex-shaped plates for vortex formation so that toxic gases penetrate into the space generated by enclosing the fuel pipe in a cylinder, and vortex-shaped plates can be formed so that toxic gases penetrate the vortex-shaped plates at the inlet through which the toxic gases pass. a noxious gas pipe having a vortex tube formed therein, and a noxious gas outlet formed with a flame reflecting plate to increase the noxious gas combustion efficiency by colliding and reflecting the flame generated by the fuel injection;
a pyrotechnic device for igniting a spark in the nozzle through which fuel is injected;
The flame reflecting plate of the noxious gas pipe has a 45 degree to 75 degree inclination angle to improve combustion efficiency by reflecting the flame and making good contact with the noxious gas. Noxious gas combustion burner that incinerates and removes harmful gas, characterized by the fact that the reflector is attached at regular intervals. The harmful gas combustion burner of claim 1, wherein the vortex tube is equipped with a plurality of tornado-shaped plates attached to the side of the fuel supply surface of the fuel pipe, so that the harmful gas passes through and a vortex is formed.
