Modeling of a Combined Kalina and Organic Rankine Cycle System for Waste Heat Recovery from Biogas Engine
Öksel, Cem; Koç, Ali (MDPI, 2022)Converting waste heat into electricity has captured the interest of scientists for years because of its enormous potential to improve energy efficiency and to lessen environmental impacts. While there are numerous applications ... -
Numerical Examination of A Solar Chimney Power Plant Designed for the Iskenderun Region
Önal, Mustafa; Koç, Ali; Köse, Özkan; Koç, Yıldız; Yağlı, Hüseyin (Konya Teknik Üniversitesi, 2022)Today, energy is accepted as the most indicator of economic development. However, the use of fossil fuels as energy sources is caused the depletion of the ozone layer, global warming and climate change. Therefore, using ... -
Optimisation of simple and regenerative organic Rankine cycles using jacket water of an internal combustion engine fuelled with biogas produced from agricultural waste
Yağlı, Hüseyin; Koç, Yıldız; Köse, Özkan; Koç, Ali; Yumrutaş, Recep (Elsevier, 2021)Internal combustion engines have a very important place in biogas production facilities to convert biogas energy to electricity. Unfortunately, although intense studies on improving internal combustion engine efficiencies ... -
Parametric optimization and exergetic analysis comparison of subcritical and supercritical organic Rankine cycle (ORC) for biogas fuelled combined heat and power (CHP) engine exhaust gas waste heat
Yağlı, Hüseyin; Koç, Yıldız; Koç, Ali; Görgülü, Adnan; Tandıroğlu, Ahmet (Elsevier, 2016)In this paper, a subcritical and supercritical organic Rankine cycle (ORC) are designed to recover exhaust gas waste heat of biogas fuelled combined heat and power (CHP) engine. The CHP engine is located in Belgium and ... -
Performance analysis of a novel organic fluid filled regenerative heat exchanger used heat recovery ventilation (OHeX-HRV) system
Koç, Ali; Yağlı, Hüseyin; Bilgiç, Hasan Hüseyin; Koç, Yıldız; Özdemir, Ayşenur (Elsevier, 2020)In this study, a novel organic fluid-filled regenerative heat exchanger used heat recovery ventilation (OHeX-HRV) system was designed. Five organic-based fluids (R11, R123, R245fa, n-Pentane and Isopentane) were selected ... -
Performance and environmental improvements of a geothermal power plant by using structural and operational modification techniques
Baydar, Ceyhun; Yağlı, Hüseyin; Koç, Yıldız; Koç, Ali; Artaş, Sultan Büşra (Institution of Chemical Engineers, 2023)Performance data from a geothermal power plant that uses a dry-type working fluid (n-Pentane) was evaluated. The experimental working conditions of the geothermal power plant were recorded. By using these recorded data the ... -
Pinch point determination and Multi-Objective optimization for working parameters of an ORC by using numerical analyses optimization method
Kocaman, Emrullah; Karakuş, Cuma; Yağlı, Hüseyin; Koç, Yıldız; Yumrutaş, Recep; Koç, Ali (Elsevier, 2022)In parallel with Kyoto, Paris and the green production agreements, the nowadays crucial subject is minimising energy consumption, increasing renewable energy usage and recovering waste heat. When it comes to waste heat, ... -
Thermodynamic analysis of solid waste and energy consumption to reduce the effects of an electric arc furnace on the environment
Koç, Yıldız; Yağlı, Hüseyin; Özdeş, Enver Onur; Baltacıoğlu, Ertuğrul; Koç, Ali (Inderscience Enterprises Ltd., 2019)In this study, thermodynamic analysis of an EAF was made to reduce solid wastes and energy consumptions. Then, the slag formation, quicklime consumption and daily energy consumption of the EAF were optimised for different ... -
