  • Sodium Monitoring TECHNICAL NOTE On Power Plant

    on high pressure boilers, and may be carried over in the steam delivered to the turbine. Once again, sodium monitoring provides a good indication of the overall steam purity level required to minimise corrosion and avoid deposition of sodium salts on the superheater and turbines. Where this takes place in the boiler, it is known as 'hide-out'.Get Price
