Abstract

Coal-fired power plants (PLTUs) play a crucial role in the national electricity system due to their ability to generate electricity on a large scale. The 2x25 MW Anggrek Steam Power Plant in North Gorontalo Regency is one of the power plants that has implemented Lamtoro biomass cofiring technology. This study aims to analyze the thermodynamic performance of the 2x25 MW Anggrek Steam Power Plant (PLTUs) under two conditions: existing (100% coal) and cofiring (85% coal + 15% lamtoro biomass). The method employed in this study utilizes thermodynamic law analysis, supplemented by cycle tempo simulations, to evaluate boiler and power cycle efficiency. The results show boiler efficiency under cofiring conditions of 82.45% (direct method) and 87.04% (heat duty method). The power cycle efficiency decreased from 23.336% (existing) to 21.652% (cofiring) due to the lower heating value of the biomass. Therefore, despite the decrease in efficiency, cofiring lamtoro biomass remains a feasible alternative fuel in PLTUs because it can maintain operational stability and has the potential to reduce carbon emissions.
