This document discusses gas turbine technologies related to fuel flexibility and integration. It covers topics such as combined cycle power plants, fuel oil treatment plants, Mapna gas turbine technologies, and a case study of the Kermanshah Power Plant in Iran. The key points are:
- Combined cycle power plants can run on natural gas, gasoil, low-BTU gases, and syngas. Fuel oil treatment plants are used to treat heavy fuel oils before combustion to protect gas turbines.
- Mapna provides gas turbine technologies with efficiencies up to 38% and nominal powers up to 183 MW. Their technologies allow operation on various fuels including natural gas and treated heavy fuel oils.
- A case study describes implementing
