Chemistry of the water-steam cycle in thermal power plants

This course is about the chemical aspects of the water-steam cycle in a power plant. Included in the program are the different types of chemicals used in boilers, potential issues in a water-steam cycle, monitoring and specifications regarding target values and alarm levels. Actions in case of chemistry-related incident are also part of the course.

The course includes:

  • Detailed aspects of chemistry in a water steam cycle, such as types of chemicals used in the boiler depending on the treatment and type of boiler.
  • Potential issues in a water-steam cycle, such as corrosion and deposition.
  • Monitoring and analytical programme, and knowledge of the specifications for the water steam cycle (normal values targets – alarm levels).
  • Chemistry aspects during transition periods: start-up, shutdown and preservation.
  • Actions in the event of an alarm.
  • Examples of incidents or deviations compared to normal chemistry.
  • The last part of the course is dedicated to exercises and a quiz.

The course addresses a wide audience, including operators, power plant chemists, plant operation or maintenance engineers, consultants and technical project managers.

A chemical engineer who has worked at ENGIE Laborelec for 10 years, Han Huynh is a specialist in water treatment (cooling water, demineralised water desalination, and the water-steam cycle) and CO2 capture and valorization. In the area of technical assistance, she has undertaken activities such as plant commissioning and chemistry reviews and audits, as well as a number of troubleshooting missions. Adopting a pragmatic approach, she discusses all recommendations with her clients taking into account their needs and the constraints under which they operate.
She also manages technical projects in the framework of research programs on carbon reduction and valorisation, and water footprint and management, as well as the European Union’s MATChING project (part of the Horizon 2020 program) which focuses on cooling water system improvement. She is the coordinator for the CO2 Lab within Engie.
