FT8 gas turbine with dry low-NOx combustor - technology and first field experience in a compressor station

FT8 is an industrial gas turbine of the 25 MW class and has been in commercial use since 1993. It is based on the aircraft engine JT8D of Pratt & Whitney, one of the most successful aircraft engines with 15,000 engines in operation. The FT8 fleet as the driving aggregate for generators and compressors has so far completed over 665,600 operating hours. Gas turbine FT8-2 with dry low-NOx (DLN) combustion chamber and the first operating experience gathered with a compressor station in Werne are being described. Explained is the combustor system. The protection and monitoring installations for maintenance of low emission values with at the same time low combustor pressure pulsations are outlined.
