CHARACTERIZATION OF TEMPERATURE AND ELECTRICAL POWER GENERATION IN A GASIFICATION SYSTEM USING CHARCOAL FROM TRADITIONAL MARKET WASTE

Abstract

The Giwangan traditional market in Yogyakarta City, Indonesia, produces over 4,387.95 kg of waste daily, of which 2.89% consists of wood and twig by-products. However, these wastes are not being effectively used to generate energy and are instead sent directly to the landfill. This study aims to convert waste into energy using a gasification system, focusing on data related to temperature and power generated from 3 kg of charcoal made from wood and twigs. The gasification system includes the following components: (1) a 22.5-litre gasifier reactor, (2) a water cooler, (3) gas filters, (4) a modified generator set with a 2200-watt power capacity, and (5) 100-watt light bulbs. Measurement instruments, including (1) a K-type thermocouple, (2) a voltmeter within a voltage stabilizer, and (3) a clamp meter for AC, were used to track the temperature and power generated by the system. Results indicated that the average reactor temperature during the pre-heating phase before the syngas entered the internal combustion chamber, was 1041°C over a period of 14 minutes. During the syngas operational phase, the maximum, minimum, and average reactor temperatures as a fuel generator were 1035°C, 924°C, and 951°C, respectively. The generator produced an average power of 723.2 watts over 50 minutes, with a maximum output of 1043.6 watts.
