High-Pressure Steam Cycle and Boiler Water Treatment

Copper evaporator tubing in a 500 psi circulating boiler would run at lower temperatures (=less corrosion) than the tubes in the 48-year copper-tubed noncondensing Stanley boiler which Pat mentioned. Still, the boiler might only last about 50 years. Rats. LOL.

The majority of the commercially available solar water heaters are constructed using copper tubing for the transferring heat to the fluid flowing within and for the collector plate. The expense of copper is making the current models extremely expensive (Plante, 1983). Currently copper is the standard tubing material used in solar water heaters.

Feb 24, 2016 · An increase in temperature results in an increase in electrical conductivity. For boiler water, the conductivity increases at the rate of approximately 2% (of the value at 25°C) for every 1°C increase in temperature. This can be written as: σ T = σ25 [1 + α (T – 25)] σT = Conductivity at temperature T (µS / cm)
