Abstract

In the recent years, energy has become a crucial issue in the world. The energy crisis caused by growth of population and depletion of world oil reserves along with the emission issue from the fossil fuels gives pressure to each country to immediately produce and use renewable energy. Coal briquette is a renewable energy which is also very potential in Indonesia. By using gasification technology, coal briquettes are burned with limited oxygen to produce a fuel-burning methane gas. The testing of coal briquette gasification aims to find out the effect of diameter size on combustion temperature, boiling temperature of water, effective flame and thermal efficiency of the furnace. The research began by supplying air from the blower with 6.5 m/s speed. Then, diameter sizes variations on coal briquettes were apllied. The diameter size used were 10 mm, 15 mm, and 30 mm. Afterwards, combustion temperature and boiling temperature of water were measured per one minute. The fidings showed that variations on diameter size were highly significant on the combustion temperature, boiling temperature of water, effective flame and thermal efficiency of the furnace produced. In the diameter size of 10 mm, the highest burning temperature was 588.33 0C, the boiling temperature was for 94 minutes, the flame effective was for 94 minutes, and the thermal efficiency of furnace was by 36.88 %. Next, in the diameter size of 15 mm, the highest burning temperature was 513.33 0C, the boiling temperature was for 78 minutes, the flame effective was for 78 minutes, and the thermal efficiency of furnace was by 39,14 %. Lastly, in the diameter size of 30 mm, the highest burning temperature was 705.66 0C, the boiling temperature was for 55 minutes, the flame effective was for 55 minutes, and the thermal efficiency of furnace was by 40.11 %. Keywords : gasification, coal briquette, diameter size
