Journal . hors experience with regenerators isthat the combustion products seek the straightest way out, andbricks that are most vitrified (the cross baffle ones) are exactlythose that catch the outgoing heat but do not present their hotside to the cold incoming air. A regenerator to be really effectivemust be larger with more friction surface where gases are rarefiedby heat and increased in volume, and smaller where the heat isleast and the volume decreased. It is highly desirable that the batch should reach the funnelas highly preheated (13) as possible by waste heat so as to givethe fresh heat as little to lose as possible—besides, heating up to1,000° drives off all the C02, though it reduces in doing so thetemperature to about 850°, but it is equally important to get thegas and air to the same temperature if it can be arranged. Forthis no better contrivance than the thin tile recuperator (Fig. 3) isknown if a constant flame in one direction has to be provided. So |- Tru u u o u u ti u 1. /l Steam injected air pipe.
