The principle and method of tracealkaline circulation treatment technology for innercooling water in generators have been presented. Special ion exchange resin had been selected for the said technology

and unique structure of the resin bed layer being adopted

making the innercooling water in generators to contain some NaOH after said treatment

hence

the water quality can be adjusted

and the corrosion of copper bars in the generator can be retarted. Because of this sytem needing no dosage of chemicals

and it is almost not neccessary to change and replenish water

thereby manpower and material resources are saved. Through application of the said technology for innercooling water in four 200MW generators and six 300MW generators

all water quality after said treatment to be superior to related standards.
