DACRS Technology11 Million hrs experience

Premixer

DLE2 enables meeting same NOx with

higher combustor airflow

Increases airflow thru premixer

New premixer and domeplate designs

Dual-annular combustor

15 premixers (DLE2) Vs 30 premixers (DLE1

New Premixer leverages TAPS technology

Co-annular pilot and main swirlers

Radial inflow main swirlers

Simplified staging operation vs. DLE1

Staging valves not needed

Available intercooler options :

• Standard intercooler

• High-temperature intercooler

(HTIC)

Future intercooler options :

• Customer-process water (CPW)

and HTIC system

Note: GE expects the CPW-HTIC

option to be available for delivery

in 2013.

Note: Engine high pressure

2xLMS100 PA in Combined Cycle -

Turkey

• Operated on SC for ~ 12 months.

• Recently closed the cycle

• 2x2x1 Configuration (HRSG 2-

pressure drum type)

• Daily cycling

• Flexibility is one of key drivers

• Expect ~ 54% CC efficiency.
