The lean, premixed H combustion system was targeted to deliver low NOx and CO emissions from 50% to 100% combined cycle load in both the Frame 7H (60 Hz) and Frame 9H (50 Hz) heavy-duty industrial gas turbines. The H System™ is the first gas turbine combined-cycle technology capable of achieving 60% thermal efficiency. The present paper describes field test performance of the combustion system during the launch and operation of the initial MS9001H installation at Baglan Bay power station near Port Talbot, Wales. The 480 MW 9H combined cycle, fired using the 14-chamber DLN2.5H combustion system, was comprehensively evaluated during the gas turbine Characterization Test program over a period of several months in late 2002 and 2003. Results are reported for exhaust emissions, combustor component durability, operability, and other key combustion system performance parameters over the full gas turbine operating range. The present paper also describes the operability of the H combustion system throughout a rigorous validation of the power plant system, including National Grid Council testing, load rejections, and other key system transients.
