EDS (Energy Sipersive Spectrometer) Analysis of Sintered Construction Material

Abstract:

This study aims to analyze elementary variation of fly ash from one Shanghai municipal solid waste incineration (MSWI) plant using EDS (Energy Sipersive Spectrometer) as a function of sintering temperature. MSWI fly ash was firstly sintered at 700°C, 800°C, 900°C, 1,000°C and 1,100°C respectively for 30 minutes, and then underwent EDS analysis. It was found that element content follows the decreasing sequence of Cl > Ca > O > K > Na > S > Fe > Cu > Si > Al > Zn >Mg. Content of Ca and O rose with increase of temperature, while Cl has a relatively reverse trend. Fly ash sintered at temperatures over 1000°C sees a sharp decrease of Cl, K, Na and S, and a considerable increase of Ca and O. Therefore, sintering temperatures over 1000°C is recommended for treatment of municipal solid waste fly ash.
