Power plant water and steam chemistry is not a background task. It affects safety, reliability, metallurgy, production, and the decisions plant teams make under pressure. In Part 1 of this conversation, Trace Blackmore, CWT, welcomes Bradley Buecker of SAMCO Technologies and Buecker Associates to examine what happens when familiar assumptions go unchallenged.
Safety Comes First in High-Energy Systems
Bradley begins with the lesson that has shaped decades of his work: safety. Power and industrial systems involve heat, flow, moving equipment, chemicals, confined spaces, lockout/tagout requirements, and PPE decisions that cannot be treated casually.
That safety lens carries directly into the discussion of flow accelerated corrosion, or FAC. Bradley explains how older thinking around removing all oxygen from high-pressure steam generation systems helped shape all-volatile treatment reducing programs. However, research following a catastrophic 1986 feedwater line failure showed that chemistry, flow conditions, pH, temperature, and piping geometry can combine to thin protective oxide layers on carbon steel.
"Water is Water" Is a Risky Mindset
Trace and Bradley then challenge one of the most expensive assumptions in industrial plants: “water is water.” Bradley explains why boiler makeup treatment, softener performance, hardness control, and operating discipline deserve attention before failures appear.
Low-pressure and intermediate-pressure boilers may tolerate a range of dissolved solids, but hardness remains a serious threat. Calcium and magnesium can form calcium carbonate scale in hot boiler environments, especially when softeners are poorly maintained, overrun, or bypassed to keep production moving. Bradley shares examples where short-term operating decisions led to tube failures, re-tubing, hydrogen damage, and costly downtime.
Layup, Stainless Steel, and Data Before Assumptions
The conversation also covers proper layup, oxygen and moisture corrosion, nitrogen capping, dehumidified air, vapor phase corrosion inhibitors, and why idle systems need a plan. Bradley reminds listeners that protecting the boiler is not enough; condensers, low-pressure turbines, and other surfaces also matter.
Finally, Bradley discusses stainless steel selection and why 304L or 316L should never be treated as a universal cure for corrosion. Chlorides, deposits, cycling in cooling towers, and pitting risk all need to be evaluated before materials decisions become expensive lessons. His closed cooling water case history reinforces the same principle: do not clean, treat, or specify based on assumption. Get the data first.
Good water treatment decisions protect people, equipment, and production. This conversation is a reminder that experience matters, but so does the willingness to ask questions, challenge old habits, and reach out before a problem becomes a failure.
