Laser gas analysis emission monitoring

The SRICI-TDLS laser gas detector is a self-contained, ready to use gas measurement module that can measure gases such as HCL, CH4, H2O, CO2, HCl, HF, or O2.

The module is specifically designed for high-precision environmental applications and is used in gas detection and monitoring systems for various industrial applications. Typical applications include process control, emissions and environmental monitoring, safety and air quality. Based on advanced tunable diode laser spectroscopy (TDLS) technology, the LGD module can accurately measure the target gas without being affected by the cross effects of other gases, and eliminates the requirement for standard measurement channels with its innovative measurement principle.
HCL laser monitoring method (extraction type)
Due to HCL being a highly active gas, chemical reactions occur during the sampling process. Traditional measurement methods, such as installing the measuring probe directly in the flue (with the light path passing through the pipeline), have problems such as easy corrosion of the transmitting and receiving probes, insufficient measurement accuracy caused by smoke and dust affecting the light intensity, loosening of components due to mechanical vibration, measurement being affected by process parameters such as temperature and pressure, and inconvenient operation and maintenance; At the same time, the long-distance extraction method may cause chemical reactions in HCL during the extraction process due to the long heat tracing pipeline, which can also result in measurement deviations.
After years of engineering experience and drawing on excellent foreign equipment such as sampling constant temperature devices, constant temperature heat tracing pipelines, high-performance lossless pre-processing systems, and laser analysis systems to measure HCL, we have ensured the stability and accuracy of HCL measurement.
The laser HCL analyzer is based on spectroscopic techniques such as tunable diode laser absorption spectroscopy (TDLAS), which has been used in many power plants or other industrial combustion fields that burn mineral fuels to monitor the concentration of HCL, NO, NO2, CO, CO2, O2 and other gases in natural emissions.
