Design of alpha type stirling machine biomass-based innovation design with the capacity of 100 watt

Abstract

Stirling machine has the advantage that it can utilize all kind of fuel, so that it is suitable for biomass utilization. In this study the analysis of best design of stirling machine different from previous study was carried out, which is design innovation on alpha type stirling machine by making phase angle become 180°, with the aims of lowering the gravitational force when cool cylinder is compressed, because the existing phase angle used is (90°) has the disadvantage of cool cylinder which is perpendicular, so that the compression is against gravitational force. The designing method was conducted by using Quality Function Deployment. The result of this study was to obtain the best variance of shape and machine stirling design dimension, which is variance 5, biomass stove- pulley and belt- was directly used. Variance 5 is chosen because it was the most suitable with the designed specification. Biomass stove is chosen as heat source, because the fuel used is classified as alternative fuel. Pulley and belt were chosen as mechanism of work transmission, because it has less noise compare to sprocket and chain. Its output work was directly chosen because its construction is simpler and the energy used is more optimal.

Analisa Isolasi Pipa Generator Mesin Stirling Tipe Alpha Sudut Fasa 180°

“…Penelitian ini merupakan pengembangan dari penelitian sebelumnya, dimana pada penelitian sebelumnya dilakukan inovasi desain pada mesin stirling tipe alpha dengan membuat sudut fasa menjadi 180 o , dengan tujuan untuk mengurangi pengaruh gravitasi pada saat silinder dingin terkompresi, karena sudut fasa yang sekarang digunakan (90 o ) memiliki kekurangan yaitu silinder dinginnya yang tegak lurus ke atas, sehingga proses kompresinya melawan gravitasi. Tetapi pada penelitian sebelumnya memiliki kekurangan yaitu pipa generator yang terlalu panjang sehingga menyebabkan banyak kehilangan energi atau panas (heat loss) sehingga kecepatan kompresi menjadi kecil [10], [11]. Sehingga pada penelitian ini melakukan inovasi dan analisa isolasi pipa generator mesin stirling tipe alpha mesin stirling tipe alpha sudut fasa 180 o .…”
