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
