Thermal Simulation of the TIAC System for Muara Karang CCPP Block 2: Feasibility Study for Power, Efficiency, and Emission Improvements
Keywords:
efficiency, greenhouse gas emissions, heat rate, output power, turbine inlet air coolingAbstract
This study conducted a thermal simulation of the turbine inlet air cooling (TIAC) system for Muara Karang combine cycle power plant (CCPP) Block 2, focusing on its feasibility for enhancing power output, efficiency, and reducing greenhouse gas (GHG) emissions. Implementing TIAC on gas turbine generator) GTG 2.1 increased power output from 235 MW to 252.2 MW gross of power, reduced the heat rate, and improved plant efficiency. Financial analysis showed viability, with the internal rate of return (IRR) rising from 14.36% to 14.44%, surpassing PT. PLN's 9.28% threshold, and the net present value (NPV) increasing by Rp. 31.1 billion. GHG emission intensity decreased from 0.6018 kgCO2e/kWh to 0.6007 kgCO2e/kWh.
