ABSTRACT:
In thermal regenerative apparatus having at least one heat-exchange section which includes a plurality of ceramic refractory elements, an upstanding hatch is provided to permit additional elements to be inserted after settling of the original charge due to wide temperature fluctuations, the gas flow through them, etc. The hatch has lower, outwardly-angled surfaces to facilitate downward and outward movement of the ceramic elements as they settle thereby preventing gas flow bypass in clearances above the elements. A light cover for the hatch has a lower, flexible metal surface that enables it to maintain sealing contact despite high-temperature effects on it.
