The paper describes an instrument for on-line concentration measurement of vaporised alkali compounds in pressurised industrial combustion and gasification processes. The measurement is based on Plasma Excited Alkali Resonance Line Spectroscopy (PEARLS) at the elevated pressure (1-3 MPa) of the process. Results are presented from laboratory calibration measurements and test measurements of sodium and potassium vapours resulting from the combustion of coal powder in a pressurised entrained flow reactor.
