Abstract
The problem of urban waste is one of the most complicated problems in Indonesia’s big cities. Utilizing municipal waste into co-firing fuel is one way to reduce waste that accumulates and reduce global emissions. Before being used, the urban waste needs to be tested for characteristics to determine its content or its combustion characteristics. This study uses Indonesian low-rank and medium-rank coal and Solid Recovered Fuel (SRF) biomass. This observation aims to decide the effect of coal-SRF blended on slagging and fouling in co-firing using a drop tube furnace (DTF). The results obtained are SRF blending up to 15% there is no slag attached. There is slight slag attached at the blending ratio of 20% and 25%, and there is a corroded part of the plate. It can happen because SRF has a high chlorine content. Overall, it shows that co-firing coal with SRF up to 25% is still safe on slagging and fouling.
