Power Plant Chemicals Webinar - Hot Topic Hour September 25, 2014
The level of knowledge demonstrated by the speakers relative to the challenges of preventing corrosion and malfunction of gas turbine combined cycle plants which are cycling hundreds of times per year and may be using poor quality source water makes a persuasive case for continuing expert advice.

Questions answered regarding HRSG water/steam chemistry and prevention of corrosion and fouling in steam generators. Even seemingly minor issues have been known to cause failures that cost power producers millions of dollars and in some cases even claimed lives. This is the ultimate cost.

EPRI’s Guideline on Chemistry for Fossil Units with Air-cooled Condensers (ACCs)
This paper provides the results of the first worldwide survey of a number of fossil and combined cycle/HRSG plants with air-cooled condensers (ACCs). It includes documentation of the surface condition of the duct surfaces, defining serious corrosion/flow accelerated corrosion regions and guidelines for operating plants with ACCs.

A systematic study of the influence of system design, station operations and cycle chemistry on corrosion product generation and flow-accelerated corrosion (FAC) was carried out at Intergen’s Coryton CCGT in Essex, UK. Coryton is a 779 MW two-by-one combined-cycle natural gas plant equipped with an air-cooled condenser (ACC). The station wanted to invest in advanced monitoring techniques with the objective of reducing corrosion in the air-cooled condenser and the potential for FAC in the heat recovery steam generator (HRSG) during normal and cycling operations, and to determine the impact of cycling operation on unit life expectancy and reliability.
