| titleOfInvention | Preheating device for low-nitrogen burner |
| abstract | The utility model discloses a preheating device for a low-nitrogen burner, which comprises a burner, wherein a centrifugal fan is fixedly arranged on the inner wall of the burner, a heat-dissipation spiral pipe is fixedly sleeved on the inner wall of the centrifugal fan, a heat-absorption spiral pipe is fixedly arranged on the outer surface of a combustion head of the burner, and the water inlet end of the heat-absorption spiral pipe is fixedly communicated with the water outlet end of the heat-dissipation spiral pipe; the water inlet end of the heat dissipation spiral pipe is fixedly communicated with the water outlet end of the heat absorption spiral pipe, and a driving device is arranged at the communicated position. This preheating device for low-nitrogen burner sets up drive arrangement to reach in the heat conduction of heat absorption spiral pipe to the heat dissipation spiral pipe, when using, centrifugal fan's wind-force is through in the helicla flute, thereby drive the driving plate in the mounting groove, under the rotation of driving plate, thereby drive the pivot, and then rotate the flight in the heat dissipation spiral pipe, make in the heat conduction of heat absorption spiral pipe to the heat dissipation spiral pipe, thereby solve the problem of heat conduction. |
