Evaluation System Co-firing Coal and Biomass Woodchip in Coal-Fired Power Plant Punagaya
Keywords:
co-firing, circulating fluidized bed, biomass, woodchipAbstract
This study evaluates the co-firing system at the PLTU Punagaya Unit 1. The primary focus of this study is to evaluate fuel characteristics, specific fuel consumption (SFC), and exhaust gas emissions when the biomass percentage is 5%. Literature review and analysis of operational data from the power plant and laboratory test results were used to evaluate the feasibility of using biomass woodchip. The study results indicate that biomass woodchip, which has a lower calorific value and higher moisture content, affects combustion stability and specific fuel consumption (SFC). However, biomass woodchip can still be used without significant performance degradation with optimal combustion settings. Additionally, there is a significant reduction in SO₂ and NOx emissions, supporting environmental sustainability targets. This study's findings on the use of biomass woodchip at the PLTU Punagaya can continue to be utilized. However, further studies are needed on biomass pretreatment methods and blending with other biomass types to reduce the potential for slagging and fouling. This research supports Indonesia's carbon emission reduction policy in the energy sector through renewable energy.
