Deviation exists in periodic water production of different condensate polishing(CP)mixed beds in a power plant

and the periodic water production of parts of the CP mixed beds was obviously low than the theoretical value.Experiments revealed that the main reasons for this problem were as follows:the inlet strainers of the CP mixed beds were blocked by resins

the resin was irregularly mixed in cation regeneration tank(CRT)

and secondary stratification of the resin occurred in the PC mixed beds.By optimization on regeneration process and transformation of the exhaust duct on top of the CRT

both the periodic water production of two beds was increased to above 1.5×105 tons

which was close to the theoretical value.
