Abstract

The invention provides a laser ignition liquid fuel combustor which comprises a combustor body, a combustion chamber, a combustion head, an air supply device, a fuel feeding device and a laser ignition device. The fuel feeding device comprises a fuel suction pump, a fuel injection pump and an atomizing nozzle. The laser ignition device comprises an Nd:YAG solid laser, a laser power source, a laser controller, a focusing lens, an optical fiber coupler, a light-guide fiber, an optical window and a laser igniter. The laser ignition liquid fuel combustor has the advantages that due to the fact that the laser ignition device is adopted, compared with a traditional electromechanical ignition combustor, the laser ignition liquid fuel combustor needs no electrode, and the electrode corrosion problem is avoided; in addition, the laser ignition liquid fuel combustor is high in interference resisting capacity, and the interference of electromagnetic waves, static electricity and other electric signals is avoided; in addition, the laser ignition liquid fuel combustor is safer and more reliable, ignition strength and the ignition moment can be effectively controlled, and therefore electric control can be achieved easily.

Description

technical field [0001] The present invention relates to a laser ignited liquid fuel burner. Background technique [0002] Laser ignition is a comprehensive high-tech laser application, which has been widely used in various fields. The laser outputs pulsed laser energy. The laser beam passes through the focusing lens to greatly increase the laser energy. After that, the laser beam travels through the optical fiber and through the optical window to the laser igniter. The high-energy laser makes the explosive temperature of the energetic material rise rapidly to ignite Explosives to achieve ignition. At present, almost all burners in the domestic market use traditional electromechanical ignition, but their safety and reliability are insufficient, the anti-interference ability is poor, it is difficult to control the ignition time, and it is easy to ablate the electrodes. The laser ignition can effectively solve the above problems, and the laser ignition liquid fuel burner is a...
