Abstract Scope |
Stringent emissions requirements and a lack of standardized measurement methods urge the need for systematic development of reliable on-line monitoring systems for diffuse emissions. A new generation long path dust analyzer based on a divergent, modulated laser transmission technique is under development. The new instrument is currently tested in a wind tunnel designed by SINTEF and installed at a NTNU laboratory in Trondheim, Norway. This "One-of-its-kind" calibration system, and the features of the open-path instrument are outlined in this paper. Further, a pilot LaserDust™ instrument was installed on site at Elkem Rana, Norway to collect data for the development of the monitoring system. We present our experience related to emission monitoring, highlighting opportunities of reliable and reproducible online quantification for modern process control to reduce waste streams. Reference measurement sampling strategies and methods for calibration and verification tailored for open-path dust lasers are discussed. |
