We are operating 2 gas turbine in synchronisation with national grid.
Both are Frame 6B with DLN-1 system with only gas firing. We run in part load 20 MW only @ atmospheric temp 45deg C. Recently control system was replaced with MarkVIe system and tuning was done. It was working perfect. For the last 3-4 weeks we are finding the CO emissions in the exhaust of gas turbine is increasing during the noon time (being in middle east atm temp reaches 45Deg C). HRSG firing also was stopped to verify the CO level. Still CO remains high. Analyzers were calibrated. Can someone guide how to proceed?
