Effects of sulfation on the ash fusibility and minerals evolution of corn straw during oxy-fuel combustion

Oxy-biomass combustion is an important technology for achieving negative CO2 emission. However, during oxy-biomass combustion, a series of ash-related problems are induced because of the accumulation of recycled SO2. In this study, the effects of SO2 on the ash fusibility were systematically investigated through ash fusion temperatures (AFTs) tests, scanning electron microscopy (SEM), inductively coupled plasma atomic emission spectrometer...
