METHOD AND APPARATUS FOR OPTIMIZING HIGH FGR RATE COMBUSTION WITH LASER-BASED DIAGNOSTIC TECHNOLOGY

摘要

A method and apparatus for optimizing boilers with high flue gas recirculation rate based with laser based diagnostic technology. A tunable diode laser is emitted from a launcher, is altered by the absorption spectra of the gas species that it intersects, and encounters a receiver. The signal is processed, then the information is used to modulate the flowrate of hydrogen blended fuel or oxygen enriched air into the burner.
