Oct 24, 2012 · If the ash content in feed coal exceeds 10%, simply small slag tap cannot pass through the molten slag even the slag viscosity is as low as liquid. Because slag flow viscosity in many cases stays at the few hundreds of centipoise range even above 1,400 o C, smooth discharge of slag cannot happen, which results in plugging the slag discharge port.
