Properties of Municipal Solid Waste Incineration (MSWI) Fly Ash during Heating Process

Wang, Xiao-Bo / Zhao, Zeng-Li / Yan, Chang-Feng / Li, Hai-bin / Liang, Xin-teng

Weight loss and heat flow during heating process of municipal solid waste incineration (MSWI) fly ash were investigated through the DSC-DTG experiment carried out from 40 °C to 1400 °C, with different heating rates (5 °C/min, 10 °C/min, 20 °C/min) and different atmosphere (N2, Air). Two main weight loss peaks were found at 800 °C - 1000 °C and 1000 °C - 1200 °C for three different samples. Weight loss ingredients were analyzed by comparing the difference of components between fly ash and slag. Then Kinetics parameters of fly ash melting were acquired by Numerical Solution using a C++ program.
