Customization
Power generation combined cycle application burning heavy fuel oil (HFO)
The 9E gas turbine has fuel flexibility, able to burn various gases and liquids including crude or residual oil, therefore offering an economical solution for countries lacking natural gas. In 2010, a 209E combined cycle solution was commissioned with residual oil in Sri Lanka to supply power to the local grid. With the injection of water, low NOx emissions were achieved.
