ABSTRACT:
A length of longitudinally extending duct assembly for heated corrosive gases includes an outer support duct and a substantially gas-tight liner. The liner is spaced from the outer support duct by a relatively yielding spacer material that accommodates expansion of the liner in directions parallel to the inner surface of the outer support duct and in directions normal to the inner surface of the outer support duct without imposing any substantial resistance to such thermal expansion.
