This system is primarily used for denitrification process control in various industrial sectors, including coal-fired power plants, aluminum plants, steel mills, smelters, waste-to-energy plants, cement plants, chemical plants, glass factories, and more.
The system utilizes Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology, which analyzes the characteristic absorption of specific laser wavelengths by gas molecules to determine gas concentration through changes in laser absorption intensity.
