This study aims to utilize waste heat released from an industrial facility at 566 °C and 1.9 bar pressure to generate additional power for the facility. The goal is to reduce the environmental impact of waste heat while enhancing energy efficiency through the application of a triple combined cycle. Initially, the high-temperature waste heat is employed as a thermal source in a gas turbine cycle. The waste heat from the gas turbine is then transferred to an organic Rankine cycle (ORC), where it is used to generate low-temperature steam. In the final stage, the remaining waste heat is harnessed in a Kalina cycle to produce additional power. This triple combined cycle allows for the efficient utilization of waste heat across different temperature ranges, minimizing its environmental impact. The proposed system not only increases the facility's energy output but also mitigates the adverse environmental effects of waste heat. The results demonstrate that the system offers an effective solution for waste heat recovery. Using the model, an additional power of 1688 kW can be produced, which contributes 29.82 % to the actual system.
