Abstract

Panas buang dari proses pembakaran pada insinerator masih memiliki potensi untuk dimanfaatkan sebagai sumber energi alternatif. Salah satu teknologi yang dapat digunakan adalah Thermoelectric Generator (TEG) yang mampu mengubah energi panas menjadi keluaran listrik berdasarkan prinsip efek Seebeck. Penelitian ini bertujuan menganalisis pengaruh proses pembakaran sampah terhadap keluaran listrik TEG, pengaruh perbedaan temperatur terhadap perpindahan panas menuju TEG, serta pengaruh perpindahan panas terhadap keluaran listrik yang dihasilkan TEG. Penelitian dilakukan menggunakan insinerator berbahan bakar sampah daun kering dengan media pendingin nanofluida Al₂O₃ berkonsentrasi 0,5 wt% sebanyak 200 mL. Simulasi termal menggunakan ANSYS dilakukan untuk menganalisis distribusi temperatur pada permukaan insinerator. Hasil penelitian menunjukkan temperatur tungku maksimum mencapai sekitar 425°C, sedangkan temperatur sisi panas TEG mencapai 109°C. Pada kondisi tersebut diperoleh tegangan maksimum sebesar 1,81 V, arus maksimum sebesar 1,70 mA, dan daya maksimum sebesar 2,64 mW. Hasil simulasi ANSYS menunjukkan distribusi temperatur berada pada rentang 297–871 K yang menunjukkan terjadinya perpindahan panas dari ruang pembakaran menuju permukaan luar insinerator. Peningkatan perbedaan temperatur (ΔT) menghasilkan peningkatan keluaran listrik TEG sesuai prinsip efek Seebeck. Dengan demikian, hasil simulasi dan pengujian menunjukkan bahwa panas buang insinerator dapat dimanfaatkan sebagai sumber panas bagi TEG untuk menghasilkan keluaran listrik dengan dukungan sistem pendingin nanofluida Al₂O₃.

Waste heat generated from the combustion process in an incinerator has the potential to be utilized as an alternative energy source. One technology that can be used is a Thermoelectric Generator (TEG), which converts thermal energy into electrical output based on the Seebeck effect. This study aims to analyze the effect of the waste combustion process on the electrical output of the TEG, the effect of temperature difference on heat transfer to the TEG, and the effect of heat transfer on the electrical output generated by the TEG. The experiment was conducted using an incinerator fueled by dry leaf waste with 0.5 wt% Al₂O₃ nanofluid (200 mL) as the cooling medium. Thermal simulation using ANSYS was performed to analyze the temperature distribution on the incinerator surface. The results showed that the maximum furnace temperature reached approximately 425°C, while the maximum hot-side temperature of the TEG reached 109°C. Under these conditions, the maximum output voltage, current, and power were 1.81 V, 1.70 mA, and 2.64 mW, respectively. The ANSYS simulation showed that the temperature distribution ranged from 297 K to 871 K, indicating heat transfer from the combustion chamber to the outer surface of the incinerator. An increase in the temperature difference (ΔT) resulted in an increase in the electrical output of the TEG in accordance with the Seebeck effect. Therefore, both the simulation and experimental results demonstrated that waste heat from the incinerator can be utilized as a heat source for a TEG to generate electrical output with the support of an Al₂O₃ nanofluid cooling system.
