| Research Abstract |
To investigate trace element emissions in coal combustion/gasification gas, we worked on the development of a rapid analytical method to monitor trace elements in vapor/aerosol phase. Double pulse LIBS (Laser Induced Breakdown Spectroscopy) system with a single optical lens and small angled two lasers were built up and examined to improve detection ranges, but it fell short of our expectations. An infrared image furnace with a quartz reactor was arranged to achieve coal combustion/gasification experiments with rapid heating. Trace elements downstream of the reactor were analyzed by single pulse LIBS. Signals from As and Sb were successfully detected. Concentration of Sb in coal combustion gas was measured based on calibration curve method.
