Abstract

Bottom ash is by-product of coal power plant that gain less attention to be utilized compared to fly ash whereas the production of bottom ash will continue to increase due to increasing of energy demand particularly in Indonesia where most of its power plant use coal as combustion material. Former researches commonly proposed bottom ash as fertilizer or soil amendment and although the idea of utilization of bottom ash as fuel had been identified years ago, study of bottom ash as fuel seems to be still limited. This research aims to investigate potential utilization of bottom ash as fuel by mixing it with carbonized biogas sludge prior to briquetting process to produce carbon briquette. The quality of briquette determined using parameters such as moisture content, ash content, and calorific value. Result shows that adding biogas sludge carbon significantly increase calorific value of bottom ash from 270.9141 Cal/g to as high as 2180.7976 Cal/g.
