PURPOSE: A pulse burner for periodically changing the flow of fuel is provided to prevent environmental contaminations by reducing generation of NOx and improve combustion efficiency. CONSTITUTION: A pulse burner for periodically changing the flow of fuel comprises a first and a second fuel supply pipe(200,210), radial and axial nozzles(202,212), an oxidant supplying port(300), and a barrier(400). The first fuel supply pipe is longitudinally placed at the center of the radiant tube. The radial nozzle is radially formed at the end of the first fuel supply pipe. The second fuel supply pipe is installed inside the first fuel supply pipe and is formed of a double pipe. The axial nozzle is formed at the end of the second fuel supply pipe corresponding to the location of the radial nozzle. The oxidant supplying port covers the first fuel supply pipe and supplies the oxidant to the radiant tube. |
