Frequently Asked Questions

How is water used in power generation?
Water is fundamental to almost every form of power generation. Steam-cycle plants (coal, nuclear, natural gas combined-cycle) use water as the working fluid — high-purity water generates steam that turns turbines. Cooling water (open-loop or cooling tower) removes waste heat from condensers — typically the largest water-volume use. FGD scrubber water (flue gas desulfurization) controls SO₂ emissions in coal plants. Process water for ash handling, demineralizer regeneration, and equipment washing. A typical 500 MW thermal plant uses 5–15 million gallons of water per day.
What water purity is needed for boiler feedwater in power plants?
Specifications scale dramatically with boiler pressure. Subcritical boilers (under 2,400 psi): cation conductivity below 0.2 μS/cm, silica below 20 ppb, dissolved oxygen below 7 ppb. Supercritical and ultra-supercritical (above 3,200 psi): cation conductivity below 0.15 μS/cm, silica below 10 ppb, sodium below 3 ppb. Heat recovery steam generators (HRSGs) in combined-cycle plants typically follow EPRI guidelines or boiler-OEM specs. Achieving these targets requires multi-stage demineralization plus condensate polishing.
What is condensate polishing and why is it important?
Condensate polishing is the high-purity ion exchange treatment of returning steam condensate before it re-enters the boiler. Even in well-maintained systems, condensate picks up trace contaminants from condenser leaks (cooling water in-leakage), boiler chemistry, and corrosion products. A condensate polisher (usually mixed-bed deionization) removes these contaminants, allowing 100% condensate return to the boiler instead of partial blowdown. This dramatically reduces makeup water demand, treatment chemicals, and waste discharge — typical savings exceed $500K annually for a single utility-scale unit.
How are cooling tower systems treated in power plants?
Power plant cooling towers are some of the largest water systems anywhere — a single tower can circulate millions of gallons per minute. Treatment includes: scale and corrosion inhibitors (phosphonates, polymers, zinc compounds); biocides on a rotation schedule (oxidizing like chlorine plus non-oxidizing like isothiazolinones); side-stream filtration (sand filters or hydrocyclones) for suspended solids; blowdown control via conductivity sensors maintaining target cycles of concentration. Many plants use reclaimed wastewater as cooling tower makeup to reduce freshwater consumption.
