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.
