Slagging Fouling Prediction of Wood Waste Blending as Co-Firing Fuel for Northern Java Power Plant

Article Preview

Abstract:

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.
