In the thermodynamic system of a 300 MW air-cooling unit, high content of silicon led to salt deposition at low pressure cylinder in varying degrees,which influenced the safety and economy of turbine unit. Through analysis,it was concluded that why polishing and the operation condition of boiler suffered ill effects can be imputed to high content of silicon. Finally,combining with the actual situation,measures were put forward to decrease silicon content.
