Modelling study of the precipitation and agglomeration behavior of metallic iron in coal slag and its effect on the slag viscosity under Shell coal gasification atmosphere

The minerals in coal are transformed to the coal slag during the entrained-flow coal gasification process. The stable operation of the gasifier relies on the smooth slag tapping process. The flow behavior of coal slag is quantified by the viscosity. The high-iron coal (w(Fe2O3)>15%, ash basis) is...
