Development of porous medium combustion for micro-power generation using Liquefied Petroleum Gas (LPG) fuel

Development of porous medium combustion for micro-power generation using Liquefied Petroleum Gas (LPG) fuel / Mohamad Fadzli Mohd Sukardi
Prestasi busa alumina berliang sebagai medium berliang dan pembakaran pemangkin mikro menggunakan Ni/Al2O3 busa pemangkin menggunakan LPG sebagai bahan api telah diselidik dalam kajian ini. Ni / Al2O3 busa pemangkin telah dibangunkan melalui kaedah penjerapan jisim basah. Prestasi yang dikaji adalah lokasi api yang dihasilkan, komposisi gas serombong, dan efisiensi proses pembakaran pada kondisi pembakaran sedikit (perkadaran nisbah bahan api/udara sebanyak 1.9 dan nisbah udara kepada bahan api lebih tinggi daripada 1) dan dikekalkan sepanjang ekperimen. Proses pembakaran bermula pada suhu ambien telah menghasilkan komposisi SO2 dan NOx yang rendah disebabkan jumlah udara yang dihasilkan untuk keempat-empat gas (CO, CO2, SO2, and NOx) adalah sangat rendah untuk kesemua ujikaji. Efisiensi pembakaran meningkat sebagaimana penurunan keliangan busa alumina di mana keliangan 22 % memberikan efisiensi pembakaran yang paling tinggi sebanyak 35.55 % tanpa menggunakan nikel sebagai pemangkin jika dibandingkan tanpa menggunakan busa alumina sebagai medium berliang, 3.55 %. Dengan mendepositkan bahan aktif, Ni pada busa alumina, keputusan yang sama telah dihasilkan di mana keliangan 22 % busa alumina memberikan efisiensi pembakaran yang tertinggi untuk 0.1 M Ni/Al2O3, 0.25 M Ni/Al2O3, 0.5 M Ni/Al2O3, dan 1.0 M Ni/Al2O3 pemangkin masing-masing sebanyak 39.54 %, 47. 40 %, 56.73 %, dan 71.39 %. _______________________________________________________________________________________________________ In this study, the performance of porous alumina foam as a porous medium and catalytic micro combustion using Ni/Al2O3 catalyst foam using LPG as fuel were investigated. The Ni/Al2O3 catalyst foam was developed through a wet impregnation method. The performances that were being studied is the flame location produced, flue gas composition, and the efficiency of combustion process at lean combustion condition (ER of LPG/air equal to 1.9 and AFR higher than 1) and keep constant throughout the whole experiment. The combustion process started at ambient temperature produced low composition of SO2 and NOx as the total air produced of four gases (CO, CO2, SO2, and NOx) is low for all samples. The combustion efficiency increase as the decrease in porosity of alumina foam where 22 % of porosity gives the highest combustion efficiency which about 35.55 % without using nickel as catalyst compare to without using alumina foam as porous medium, 3.55 %. By the deposition of active material, Ni on the alumina foam, the same result were obtained where 22 % porosity of alumina foam gives the highest combustion efficiency which about 39.54 %, 47. 40 %, 56.73 %, and 71.39 % for the 0.1 M Ni/Al2O3, 0.25 M Ni/Al2O3, 0.5 M Ni/Al2O3, and 1.0 M Ni/Al2O3 catalyst, respectively.
