ABSTRACT:
Method and/or system for removing liquid slag from a pressurized gasifier. Hot liquid slag is quenched in a quenching medium such as water. The quenched and solidified slag is crushed to a maximum particle size. The crushed slag and quenching medium are alternatively connected to opposite ends of a floating piston while the other end is connected to an outlet for disposal of the slag. The crushed slag and quenching medium are subjected to the gasifier pressure so that the piston acts to forceably eject the mixture through the outlet.
