Containment of very hot fluids in permeable conduits

Abstract From the Canadian patent

Fluid permeable wall members through which an auxiliary fluid is passed against pressure exerted by a fluid to be contained, which wall member is composed of inorganic fibres may be used to contain hot fluids or fluid otherwise having a deleterious effect. Vacuum formed shapes composed of refractory inorganic fibres may be used to contain fluids having temperatures of over 2500°C such as gases which have been heated by electrical discharge means for use in the vapour phase manufacture of oxides of titanium iron, aluminium, silicon or zirconium and offer low capital costs combined with resistance to thermal shock.
