In order to meet the demand of slagging for entrained flow gasifier, addition of refractory agent kaolinite and coal with high SiO 2 and Al 2 O 3 contents was applied to improve ash flow properties of low-rank coal including fusion temperature and viscosity. The FACTsage software package was used to predict proportion of solid phase and minerals as a function of temperature...
Experiments were conducted on the selected ashes with different additions of CaCO 3 for understanding the effects on slag flow properties including ash fusion temperatures, slag viscosity, temperature of critical viscosity and type of slag. ICP-AES, XRD and FTIR analyses were applied to determine the component and structure of the slags. Factsage was used to calculate liquidus temperatures...
