火力発電所排煙成分のレーザー計測 : 微量SO_3の連続自動レーザー計測技術の展望 Laser Measurement of Flue Gas Constituents in a Fossil Fuel-Burning Power Plant
Measurement of flue gas constituents in fossil fuel-burning power plants is necessary for prevention of corrosion damage to plant machinery and for environmental protection. Optical measurement techniques for continuous monitoring of NO<SUB>x</SUB> and SO<SUB>2</SUB> have been well-estabilished, but monitoring of SO<SUB>3</SUB> still relies on sampling and chemical analysis. Since SO<SUB>3</SUB> forms sulfuric acid upon reaction with water vapor and causes corrosion damage, its continuous, real-time monitoring is of importance. This paper provides a review of optical SO3 measurement techniques, and presents some experimental results on spectrally resolved measurement of SO<SUB>2</SUB> and SO<SUB>3</SUB> using Raman scattering.
