The process design and operation situation of as moke plume treatment retrofitting project in a power plant

as well as the design features

operation situation and optimization scheme of the smoke plume control system are introduced. In the optimization scheme

the thin-walled elliptical titanium tubes arranging in line are adopted

which can greatly reduce the resistance of the flue gas condenser. The condensate water is discharged into the cooling tower directly

which can greatly simplify the condensate system. The mass concentration of dissolved solids in condensed water is 41～53 mg/L

the removal amount of SO_3 by flue gas condenser is 0.503～0.696 mg/m~3

and that of condensable particles is 0.797～1.169 mg/m~3. After eliminating the flue gas reheater and optimizing the configuration of cooling water circulating pump to 20%

30% and 50%

the increased service power consumption rate of the smoke plume control system will be reduced from 0.161%～0.205% to 0.056 6%～0.069 5%. This paper can provide guidance for the safe and economical operation of smoke plume control system for the same type units.
