DSI Effectiveness Factors
 Reagent Properties – physical and chemical
 Reagent reactivity
 Reagent surface area
 Reagent porosity
 Flue Gas Properties
 Temperature
 Flue gas moisture
 Other competing acid gases
 Injection System Configuration
 Particulate control device
 In flight residence time
 Reagent mixing
 Injection location

Calcium based Additives
for DSI
 Reaction of Ca(OH)2 with acidic gas components:
 Acid – Base reaction through Gas – Solid contact
 Surface area and pore volume very important
