Abstract
A spray dryer disperseris described for use in a spray dryer absorption (SDA) systemfor flue gas FG impurity reduction. As such, the spray dryer disperserdisperses absorbent liquid or reagent slurry droplets into contact with a hot flue gas FG stream containing gaseous impurities to produce a flue gas FG stream of reduced impurity content and dry powder end products EP. The spray dryer disperseris useful in larger capacity SDA vesselsof approximately 12 to 22 meters in diameter or larger, to avoid dispersershroudscale deposits, to avoid reagent slurry spray cloud suppression, to avoid vesselwallscale deposits and to achieve increased droplet rotational momentum for increased droplet flue gas FG penetration for efficient impurity reduction.
