Scheimpflug LIDAR for Power Plant Monitoring

To optimize the efficiency of power plants, real-time information about the local operating conditions is supremely important. As the environment inside the boilers is hardly appropriate for traditional measuring techniques, alternative methods are useful to measure the parameters like temperature and species concentration. In such conditions, the Scheimpflug-Light Detection and Ranging (S-LIDAR) technique, which requires special condition of detection configuration, can be a good alternative. In this work, the S-LIDAR system was developed for measurement inside the furnace operated in simulated conditions of power plants. A green laser operating at 532 nm wavelength was used as a continuous light source and was focused into the tube furnace. Scattered light coming back from the gas species inside the furnace was collected to infer the information about the conditions inside the furnace.
