Feedwater the oxygenase treatment (OT) is a high purity feed water by adding an appropriate amount of oxidant (O2 or H2O2) in order to achieve the purpose of thermal equipment corrosion mitigation , feed water deaerator the AVT reducing hydraulic conditions opposite is an oxidizing sexual hydraulic conditions . Using OT treatment , the decrease in the amount of pot sediments , reduced corrosion damage , the DC furnace tube and the heater pressure drop quickly elevated the problem has been resolved , boiler cleaning frequency is reduced , condensed water purification devices to extend the run cycle , the feedwater piping FAC great improve . Reduce the fouling rate of corrosion of the water supply system and the thermal system , slowing Turbine fouling and salt accumulation and prolong boiler chemical cleaning cycle , we propose a combined water treatment embodiments , plus oxygen systems and the installation of additional sampling device , replacement the condensate polishing mixed bed resin , and water supply plus oxygen transformation test processing oxygen treatment trial . Switch to the feedwater OT processing technology , running through a period of time , the quality of the water vapor in the # 4 unit has been significantly improved , extended polishing run cycle , at the same time , the furnace residual salt dissolved dirt began to release water quality preferably improved.
