- Abstract
The use of biomass in co-firing in coal-fired power plants is one step to achieve the renewable energy mix target in Indonesia. Several aspects need considering to implement co-firing, including the slagging fouling aspect. It has the potential to interfere with process performance, reliability, and plant life. In this study, an investigation was carried out on the potential for slagging fouling in co-firing of coal and sawdust 10% (C10) during combustion with a drop tube furnace (DTF). From the ash analysis, coal and C10 let in the lignite ash type. Predictive calculations carry out to complete the DTF test. Even though the prediction of slagging based on the calculation is low to medium and fouling medium to high, the combustion test tends to be low to medium. In the probe’s observation on combustion at DTF, ash deposit on coal is less than that of C10. For C10, the probe temperature of 600 °C represents the superheater area (slagging), and the supercritical temperature of 700 °C contains little sticky ash while 550 °C representing the fouling area is relatively clean. The addition of 10% of sawdust to the combustion system increased the risk, but within safe limits.
