Abstract

Indonesia has an energy mix target of 23% until 2025 in coal-fired power generation, a mixture of coal with biomass. The compound needs to be analyzed first to determine the combustion characteristics. This paper describes the characteristics of combustion of coal and sawdust (90%: 10%). In the TGA and DSC analysis, a blend of coal and sawdust 10%, C10, Tig C10 shows the highest value of 255.5 °C, linked to 100% coal with 294.6 °C, and 100% sawdust 247.9 °C. Furthermore, the peak area in the heat flow, C10, has the highest 7974.94 °C related to coal and sawdust. Besides such, the point reaction C10 at 383.1 °C has the highest value. Despite, the Tbo in C10 is the lowest associated with coal and sawdust, 581.5 °C, 632.6 °C, 775.4 ° C., While the Tmax C10 is at 409.7 °C between Tmax coal and T max sawdust. From the results of the Proximate and ultimate analysis, C10 reveals H: 4.59%, C: 59.3%, ash: 5.8%, Volatile matter 43.13%. This paper’s analysis results show that the characteristics of C10 (90% coal and 10% sawdust) have an identical value with coal.
