The electrode boiler is 99.9% efficient with almost all the energy consumed producing steam. Losses are radiant heat from the vessel only. During the operation of the boiler, it is fed with water which contains conductive substances like salts. Because the departing steam is free of these substances, conductivity of water increases.

Chapter 17 - Measurement Of Steam Purity

The specific conductance of a sample, measured in microsiemens (µS) or micromhos (µmho), is proportional to the concentration of ions in the sample. When boiler water is carried over in steam, the dissolved solids content of the boiler water contaminates the steam, and steam sample conductivity increases.

Controlling TDS in the Boiler Water

Conductivity measurement in the boiler. It is necessary to measure the conductivity of the boiler water inside the boiler or in the blowdown line. Obviously, the conditions are very different from those of the sample obtained via the sample cooler which will be cooled and subsequently neutralised (pH = 7).

Steam Purity - Western Regional Boiler Association

Steam Purity versus Steam Quality •Steam purity is the condition of the steam in regards to the purity of the chemistry of the steam expressed as ppb (parts per billion) of TDS, sodium, cation conductivity or silica in the steam •Steam Quality is the condition of the steam in regards to the % of moisture or boiler water carryover in the steam

Application Note: Monitoring Steam Purity in Power Plants

Table 1 - Conductivity of ammonia solutions containing small amounts of sodium chloride. Maintaining steam purity through phase separation is physically impossible in plants having supercritical steam generators. Because the pressure in the steam generator exceeds the critical value, water and steam cannot coexist, and the heated water becomes
