Abstract
The slag tap of a gasifier is offset from the geometrical axis. Coalescent, molten, residual ash from incomplete combustion is directed to a hearth where residence time provides further combustion and a reduction in the volume and temperature of the resulting slag. The reduced volume and temperature ash is then directed to a slag tap after which disposal is accomplished by conventional means.
