Molten Slag Flow and Phase Transformation Behaviors in a ...

A slag flow submodel has been developed to simulate the slag flow and phase transformation behaviors in coal gasifiers. The volume of the fluid (VOF) model is used to capture the free surface of the slag flow, and the continuum surface force (CSF) model is employed to calculate the surface tension between the gas phase and the liquid slag phase.

For downflow coal gasifier (GE gasifier), coal slurry and oxidant are introduced from the top of the gasifier. The hot raw gas produced during the gasification process flows toward the bottom of the gasifier. The ash forming components melt in the gasifier, flow down the walls of the reactor, and finally leave the reactor as a liquid slag.
