| Abstract: | To reduce the formation and peeling-off of oxide scales on high-temperature heating surface of boiler, and the sediment of oxide scales in pipeline and flow path of turbine, a study has been carried out on the oxidizing treatment of feedwater, oxidation control of heating surface, peeling-off prevention of oxide scales and control optimization of feedwater oxygenation, after which countermeasures and noteworthy items are put forward for control of the oxide scales in 1 036 MW units. Application results prove above measures to be effective in controlling the generation, peeling-off and sediment of oxide scales on heating surface of boiler, which would ensure safety and reliable running of the units. |
