Summary

The thermal efficiency of a glass tank regenerator is mainly determined by the product of heating surface and convective heat transfer coefficient (hc). The heating surface offered by chimney block checkers is no doubt larger than that provided by any other checker system. Our main endeavor has been to show that heat transfer, also, is better in chimney block packings. This was done by measuring the heat transfer in different checker systems (chimney blocks, pigeon-hole, open basket-weave and cruciform packings) in a semi-industrial test regenerator. The results show that chimney blocks with lateral openings provide significant advantages with respect to heat transfer.
