<p>IMPROVEMENTS IN OR RELATING TO THERMAL REGENERATIVE APPARATUS In thermal regenerative apparatus having at least one heat-exchange section which includes a plurality of ceramic heat exchange elements 7, an upstanding hatch 10? is provided to permit additional elements to be inserted after settling of the original elements to be wide temperature fluctuations, the gas flow through them, etc. The hatch has lower, outwardly-angled surfaces 11?, 11? 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 20 for the hatch has a lower, flexible metal surface that enables it to maintain sealing contact despite high-temperature effects on it.</p> |
