In thermal power generation companies, refined ash (LOI<6%) from pc firing furnace has bought benefit to the companies through recycling in such as making light weight aggregate. However ash having high LOI which is not able to reuse is still burying in the ground. To obtain refined ash, re-burning of high LOI ash(LOI>6%) in pc firing furnace can be an alternative. In this study, numerical analysis was performed to reveal the effect of ash re-burning. Based on the numerical results, 2%wt ash and 4% excess air condition is suitable for pc firing furnace as aspects of temperature and emission.
