“…High Fe2O3 may accelerate ash deposit formation that result in ash problem because of low melting point [16], [17]. In other hand, high MgO have positive effect in increasing the melting point of ash and reduce slagging [18], [19]. Ash fusion of Coal A is found to be the lowest while the other coals have varied value higher than 1200ºC.…”

Indonesia has implemented co-firing as a step for renewable energy utilization. Power plants in Northern Java could utilize wood waste from surrounding wood processing industries as co-firing fuel. In this study, wood waste with high value of ash fusion and stock coals of power plant were used as samples. Blended coals from stock coals are selected based on calorific value, slagging-fouling-abrasion prediction, and softening temperature prediction. Selected blended coals are mixed with wood waste in percentage of 10 wt% to 90 wt% to produce co-firing fuel which then predicted for risk tendency of slagging-fouling-abrasion by theoretical indices. The result shows that the addition of wood biomass increases the slagging, fouling, and abrasion tendency. In this study, addition of 20-30 wt% wood waste to blended coals can still be recommended with the medium risk of slagging-fouling and low risk of abrasion tendency.

“…Alkali and chlorine can trigger ash deposit issues because it can generate KCl or NaCl, accelerating oxidation of steel surface [8,9]. Moreover, the coal reserves in Indonesia is dominated by low quality coal that can increase potential of ash deposit problem due to high sulfur and sodium content [10]. Even though sulfur theoretically can decreases the amount of chlorine in deposit [11,12], sodium can decrease the heat transfer performance because it can make ash deposit worse [13][14][15].…”

“…Despite the fact that SRF has potential to be used as co-firing fuel, it mostly contains high alkali and chlorine that needs to be investigated. Moreover, the condition of Indonesian coal, that mostly contains high sulfur and alkali, also needs to be considered [10]. Initial slagging-fouling prediction using empirical indices can be conducted before the implementation in the power plant.…”

SRF can be utilized as co-firing fuel in power plants in order to provide more green energy and decrease the waste landfill. However, the characteristics of SRF with high potassium and chlorine need to be investigated first to avoid ash problem aspects in the future. This study aims to obtain initial prediction of slagging, fouling, abrasion, and corrosion for SRF and high-sulfur coal blend using empirical indices. This study used five slagging parameters, four fouling parameters, one abrasion parameter, and two corrosion parameters. The result shows that SRF contains high ash content, chlorine, Fe2O3, CaO, and K2O, that affects ash deposit formation like slagging, fouling, abrasion, and corrosion. Therefore, composition of 0-15 wt% SRF is more suitable than other compositions.

Biomass serves as an alternative energy solution for decarbonizing coal-fired power plants, which have been reactivated in several countries due to the global energy crisis. Oil palm waste, owing to its abundant availability, holds significant potential as a biomass fuel. This study aimed to investigate the combustion performance of various oil palm wastes in comparison to coal. Biomass combustion is associated with ash-related problems such as slagging, fouling, and corrosion, which may accelerate ash deposit acceleration, reduce heat transfer, and damage refractory equipment in boilers. Ash-related problems were evaluated using the method commonly adopted for solid fuel, including experimental drop tube furnace combustion and ash observation. The results indicate that each oil palm waste has different combustion characteristics. Palm leaves, empty fruit bunch, and palm fronds with clean probe observation have a relatively low tendency of slagging and fouling and can be recommended as biomass fuel for co-firing. However, their high alkali and iron contents need to be considered. Palm fiber has similar combustion characteristics to coal, but it has a high slagging and fouling tendencies. The palm stems with high chlorine content have a high corrosion tendency confirmed by probe observation, scanning electron microscopy, and X-ray diffraction analyses.
