Abstract
A blast heating apparatus includes an inner metal shell and an outer metal shell defining therebetween a gap filled with at least one pourable dry material, for example a mixture of SiC and graphite. To prevent excess pressure in the gap and to prevent condensate from entering the gap and attacking the outer shell, a piping system connects the gap to an area below the grate chamber of the blast heating apparatus.
