Temperature And Electrical Power Characterization On Gasification System Using Biomass Charcoal As A Fuel

``Giwangan`` traditional market located in yogykarta City, Indonesia has a potential waste generation of 4387.95 kg/day where 2.89% is wood/twig waste. So far, the wood/twigs waste have not been utilized by the officers of the market to become energy (Waste to Energy), therefore, the waste directly discharged into the landfill. This research is aimed to get the data of temperature characteristic of the reactor and electric power generated from the gasification system using 3 kg charcoal from wood/twigs waste so that from this research it is expected to reduce the waste disposal waste for the waste of wood/twigs from ``Giwangan`` market. The gasification system used consists of: (1) gasifier reactor capacity 22, 5 Liter; (2) condenser; (3) gas filters; (4) modified generator set with power capacity is 3500 Watt and (5) light bulbs with the capacity of 100 Watt. Measurement equipment required to know the character of temperature and electric power generated from this gasification system are: (1) K type thermocouple; (2) Voltmeter contained in voltage stabilizer; (3) clamp meter for AC current. The results showed that the average temperature of the reactor for the pre-heating process before syngas enter the internal combustion chamber is 1041oC with the total time required is 14 minutes. The maximum, minimum, and average reactor temperature in the syngas operational process as a fuel generator set respectively is 1035oC; 924oC; and 951oC. The average electric power generated from the generator set with syngas fuel is 723.2 Watt with operational time for 44 minutes. while the maximum power generated is 1043.6 Watt. From the average of electric power using syngas fuel concluded that this energy conversion system is only able to generate power 20.7% of the maximum power capacity in the generator set.
