Abstract (en)
[origin: US4744750A] Intensive undercar cooling is achieved in the latter portion of a tunnel kiln by (a) a continuous undercar longitudinal cooling air flow or (b) by transverse undercar sub-chambers in which heat exchangers are used to set up local cooling connection currents within each sub-chamber. Air flows in the undercar channel are substantially prevented in the heat-up zone and up to about the middle of the firing zone. Pressure equalization is permitted with respect to the firing chamber thereabove but very little air will actually pass therebetween in the sensitive heat-up zone because there is no other substantial air passageway leading into or out of the sub-chambers formed by aprons depending from the kiln cars.
