Interrelations and interactions between the mechanical and thermodynamic design, material properties, and steam and deposit chemistry are discussed and recommendations and corrosion design rules and requirements pertinent to turbine corrosion are given.
Copper Deposition and MW Loss: Problem and its Solution
This paper gives information on the problem of copper deposition leading to MW and efficiency loss occurring in steam cycles and available solutions.
Steam Turbine Problems and Their Field Monitoring
This article describes typical turbine corrosion problems and the monitoring techniques used to predict, prevent, and troubleshoot them. The effects of corrosion on turbine efficiency are covered.
Designing Steam Cycles to Avoid Corrosion
Countering corrosion in boilers, steam turbines, condensers, HRSGs, and other steam- or water-handling equipment is best done during the design phase.
Deaerator Corrosion: An Overview of the Design, Operation, Experience and R&D.
Possible material, fabrication, design, and operation and water chemistry effects and stress courses are discussed in relation to deaerator and storage tank weld corrosion cracking.
Plant Alert: Don't Let Erosion-Corrosion Compromise Safety
Thinning of pipe walls and corrosion of other components in high-purity feedwater and steam systems can have catastrophic consequences. Take time to review the problem and apply some important preventive steps.
Control of Erosion-Corrosion of Steels in Wet Steam
The combined phenomenon reduces the integrity of piping and major cycle components, and is a prime contributor to sludge and crud buildup in both drum boilers and nuclear steam systems.
Cycle Chemistry
Corrosion and Water Chemistry Problems in Steam Systems
This paper summarizes problems and solutions identified during over 100 root cause analyses and plant audits of fossil fuel utility and industrial power plants, including combined cycle units.
Understanding Steam Cycle Chemistry
Chemical-transport characteristics are important in selecting a water treatment program, establishing chemistry control limits, managing the ingress and removal of impurities, and troubleshooting water treatment problems.
Presents an outline of cycle commissioning guidelines and a brief description of selected case histories where delays of commercial operation and equipment damage resulted from insufficient water chemistry-related commissioning.
Tight Control of Cycle Chemistry Key to Successful Commissioning
In any steam cycle, more damage can be initiated during pre-commissioning, commissioning, and early operation, than during the following years of normal operation.
Effective Cycle Chemistry Control
Background on water chemistry and corrosion is given and sources of impurities, selection of water treatment, transport of chemicals around the cycle, and the selection of sample points and monitored parameters are discussed.
Current Water Treatment Practices: Utility and Industrial Steam Systems
This article gives the technical basis for selection of water treatment programs and summarizes the common water treatments used in utility and industrial steam systems.
Water Chemistry and Corrosion: Missing Knowledge
This paper discusses the main water chemistry and corrosion processes and problems associated with steam generation which are not sufficiently understood.
Phosphate hideout can result in changes of pH, as well as the concentrations of phosphate and other chemical species in the boiler water.
