Investigation of Biomass Fly Ash in Thailand for Recycle to Glass Production

This study investigated the composition and phase of major biomasses fly ash in Thailand at different sintering temperatures by X-rays fluorescence spectrometer (XRF) and X-Rays Diffractometer (XRD). All biomasses were sintered at different temperature (400 °C, 600 °C, 800 °C, and 1,000 °C) under same condition. The result found that Rice husk ash, Sugarcane leaves ash, Straw ash and Plam petiole ash at all sintering temperatures and Bagasse ash at 800 and 1,000 °C have silica content of > 50 wt.%. The main phase of Rice husk ash, Sugarcane leaves ash, Straw ash, Plam petiole and Bagasse ash was found to be SiO2 form. Theses result indicate that Rice husk ash, Sugarcane leaves ash, Straw ash, Palm petiole ash and Bagasse ash may be use substituted or additive for a silica source in the glass manufacturing process.
