The technical principle of laser fire starter
The laser igniter includes a laser power supply and a Laser pointer generator, as well as a laser ignition nozzle. The laser ignition nozzle is located on the ignited equipment and extends into the equipment, in contact with the combustible gas mixture. At the laser ignition nozzle, the center line of the laser beam is on a branch line with the center line of the laser ignition nozzle. A laser igniter, belonging to the field of ignition equipment, comprises a plurality of laser components, the laser component is arranged in a fixed part, the laser components are far away from the fixed part of the end to emit parallel light beams. The beam is focused 10-30mm away from the fixed component, and the power of the laser component is 100-150MW. The laser igniter has the advantages of simple structure, convenient operation, high production efficiency and high safety.

In the existing technology, boilers, automobiles, industrial furnaces, domestic gas stoves, gas water heaters, soot blowers, etc., all use high voltage discharge spark ignition. The device is ignited by a power supply circuit, which then uses a spark generated by a discharge between electrodes. When the operation is not standardized, the current density tolerance of the discharge section is exceeded, the pulse interval is too small, carbon deposition between the electrodes, or bad shoulder in the use of the environment will also cause carbon deposition between the electrodes, will make the electrode short circuit without sparks, resulting in ignition failure. In many situations, such as boilers, burners, industrial furnaces, torches and gas discharge systems, it is necessary to ignite the flame reliably. The existing ignition devices are mainly electric ignition, which uses high voltage ignition, arc ignition and incandescent electric ignition to ignite the flame. The ignition device is mainly composed of electric ignition part and other auxiliary parts. The electric ignition part includes an electric ignition element and an electrode. The electric ignition element generates an electric spark through the electrodes that ignites the combustible mixture, forming a steady flame to complete the ignition. The task. However, the electrode part of the ignition device is exposed to the high temperature of the ignition flame, which is easy to form carbon and corrosion damage. High voltage conductive rods and high voltage cables may leak, easily deform and break under high temperature corrosion, which may lead to ignition failure and even lead to ignition systems not working properly, and such defects in existing products vary in ignition control, installation, reliability, maintainability and life span. The laser igniter technical scheme is realized as follows: the laser igniter comprises a plurality of laser components, the laser components are arranged in the fixed parts, the laser components are far away from the fixed parts of the end of the emission of parallel light beams. The laser beam from the laser module converges into a focus 10 ~ 30mm away from the fixed module, and the power of the laser module is 100 ~ 150MW.
