ABSTRACT:
A slagging gasifier has a hearth comprising an annular solid cast structure formed from a high thermal conductivity metal such as copper and shaped to fit above a slag tap of the gasifier. The hearth is provided with one or more integrally formed passageways for circulating a coolant liquid therethrough and has an upper tundish surface with a slope of at least 10.degree. to the horizontal (preferably between 25.degree. and 45.degree.), across which tundish surface the molten slag flows downwardly and inwardly towards to slag tap. The annular structure may be formed from at least three sector-shaped cast parts secured together in situ in the gasifier.
