The Potential Of Biomass Co-firing In Overcoming Coal Limitation In Steam Power Plants

Abstract

The limitations that lead to coal scarcity are interesting to study, because coal is used as the main fuel source in steam power plants (PLTU). In this study, the use of biomass made in the briquette model for biomass cofiring is offered as a substitute for coal in PLTU. The materials used in biomass cofiring here are abundant and rarely used materials, such as sugarcane waste, palm oil waste, corn waste, wood saw waste, and durian fruit waste. The results of the biomass cofiring potential are measured based on proximate testing, where the results obtained by the calorific value of the materials used are quite high, with the highest material being rice husks which have a calorific value of 6800 kcal / Kg where this calorific value is higher than the calorific value of subbituminous batubaru which is 4600-6400 kcal / Kg. so that its potential as a substitute for coal at PLTU needs to be reviewed as a step towards the continuity of electricity availability at PLTU.
