Gasification GASIFICATION OF ORGANIC WASTE IN UPDRAFT GASIFIER: The Effect of water content of organic waste on the quality of the gasification process

Abstract

The majority of Indonesia's waste is organic and could potentially be converted to energy. The most effective method for converting waste into energy is gasification with updraft gasifier. Different types of waste are contained in organic waste, which has a high moisture content ranging from 16.95% to 53.74% collected from TPST Piyungan, Yogyakarta. The effect of moisture content which are categorized as low, medium, and high on operation time, fuel conversion rate and heating rate is the main thing observed in this study. The ideal value for the organic waste moisture content that can be obtained for a successful gasification operation is 15.68%. The operational time range of 61.57 to 193.69 minutes, with optimum value of 66.68 minutes, sehingga menghasilkan nilai FCR optimal sebesar 38,28 gram/menit dan nilai laju pemanasan dengan nilai berturut-turut untuk IH (Initial Heating Rate) 37,10 ^oC/menit dan MH (Maximum Heating Rate) 19,96 ^oC/menit. The desired product quantity in ideal conditions is 86% for gas, 8% for liquid, and 6% for solids. Based on the complete testing process, the quantity of gas products (55.31 to 88.65%), followed by liquid products (1.64 to 4.57%) and solids (9.71 to 40.12%).
