OpFlex™ Start-up NOx and Start-up Fuel Heating

Start Faster, Reduce Costs

Building on the technology of Advanced Fuel Scheduling, GE has reduced NOx emissions during start-up and shutdown of 7FA+e (PG7241) gas turbines. Using OpFlex Start-up NOx, the new start-up combustion mode will allow for less than 25 ppm NOx at approx. 20% load and above.

During the start-up of gas turbines with heated fuel, a hold in the start-up sequence is often required while the fuel reaches the rated temperature. OpFlex Start-up Fuel Heating reduces or eliminates this hold, enabling a faster start and helping to reduce start-up costs.

Benefits

Start-up NOx
  • Reduce NOx emissions during start-up and shutdown
  • Reduce visible emissions during start-up, which may enable improved relations with site neighbors
  • Free up NOx credits to be sold, or reduce NOx credits that must be purchased
Start-up Fuel Heating
  • Reduce start-up fuel consumption
  • Reduce start-up time
  • Reduce NOx produced during start-up (by shortening the duration of operation in high-NOx-producing combustion modes)

Applicable to 7FA+e (PG7241) gas turbines with DLN2.6 combustors and Mark™ V or higher controls.
