1. The document is a block diagram of the Korangi Creek combined cycle power plant in Karachi, Pakistan. 2. It shows the main components which include two gas turbines, two heat recovery steam generators (HRSGs), and one steam turbine that generates electricity. 3. The gas turbines are fueled by natural gas, and their exhaust is used to generate steam in the HRSGs which then drives the steam turbine connected to a generator to produce additional electricity.
