Slide 11: Dual Flue Gas Conditioning for Emissions Control
DUAL FLUE GAS CONDITIONING FOR EMISSIONS CONTROL When, why and how? 11
Slide 12: When Dual Flue Gas Conditioning Is Required
WHEN DUAL FLUE GAS CONDITIONING IS REQUIRED • Changing fuel mix • Many factors go into the design of particulate collection but ultimately the fuel mix has to be restricted due to economics. • Changing regulations • Emissions limits become more restrictive as technologies develop and economics permi
Slide 13: Why Dual Flue Gas Conditioning Is Required
WHY DUAL FLUE GAS CONDITIONING IS REQUIRED Reducing resistivity is only part of the story POOR PERFORMANCE • Agglomeration of fine MARGINAL particles can reduce re- PERFORMANCE entrainment in ESPs GOOD • Agglomeration of fine PERFORMANCE particles can reduce dP in Fabric Filters GAS TEMPERATURE °C I
Slide 14: Why Dual Flue Gas Conditioning Is Required
WHY DUAL FLUE GAS CONDITIONING IS REQUIRED • Injecting ammonia can improve utilization (uptake) of the SO3, SO3 H2O SO3 H2O forming ammonium bisulphate; resulting in more effective NH3 H2SO4 resistivity control. H2SO4 • Injecting ammonia can also NH4HSO4 promote agglomeration ASH ASH ASH SO3 Dual 14
