Abstract :A comparison of the energy production from a steam turbine system utilizing waste heat and a solar power plant (SPP) in the same region was conducted. The study aims to analyze the potential energy production of both systems and evaluate investment viability. The steam turbine system enhances energy efficiency in industrial facilities by generating electricity from waste heat, which is produced during furnace operations. The waste heat availability and quantity depend on fuel types, with natural gas and petroleum coke commonly used. While petroleum coke produces more waste heat, natural gas is cleaner but generates less. This variability impacts electricity production, with an average daily output of 7.56 MWh. In contrast, solar power plants are sustainable and renewable, typically requiring lower initial investment. Solar energy production depends on factors like geographical conditions, sunlight exposure, and panel efficiency, with fluctuations in output due to varying environmental conditions. Both systems were evaluated based on payback periods and energy production capacities. The steam turbine system offers stable production in large facilities with continuous waste heat, but its efficiency depends on fuel types. Solar power plants provide lower initial costs and shorter payback periods but can be affected by environmental factors. The study concludes that each system has its own advantages and disadvantages, and the most suitable system should be chosen based on local energy needs and environmental conditions.
